A red eye is one of the first and most common symptoms of conjunctivitis. Conjunctivitis is the inflammation of the tissue that lies over the white part of the eye and lines the inner side of the eyelid. It is usually the result of a viral infection and can easily spread from one person to another. Conjunctivitis can also be a symptom of STDs like gonorrhea or Chlamydia. In newborns, conjunctivitis can be vision threatening while in grownups it is not considered a serious health risk.
The symptoms of conjunctivitis differ according to the cause of the infection. Some common symptoms of conjunctivitis are:
* Green or white discharge from the eye
* Redness of the white part of the eye
* Inflammation of the eye lid
* Waking up to crusted yellow discharge
* Itchiness and burning in the eyes
* Increased sensitivity to light
* Blurred vision
An eye examination and testing a sample of the fluid secreted by the eye can be used to diagnose conjunctivitis. It can easily be treated at home and does not require hospitalization. Antibiotics are often given in the form of eye drops and ointments to treat conjunctivitis. These usually need to be applied 3-4 times a day for a period of 5-6 days. Wash your eyes before putting the eye drops. Once applied, close your eyes and roll the eyeball around to distribute the medicine and keep it from overflowing out of the eye. Wash your hands immediately after applying the eye drops.
Viral conjunctivitis is highly contagious. If you are suffering from it, you should take a few days off work and restrict your social interactions. Wash your hands frequently as you may unconsciously rub your eyes. This is especially important with regards to meals and finger foods. Also, avoid sharing towels, pillow cases etc to minimize the transmission of the disease from one person to another.
Avoid using makeup while being treated for conjunctivitis. With conjunctivitis, the eye is more sensitive to irritants and thus a speck of makeup can worsen the situation. Also avoid contacts. If you wear contacts regularly, dispose the current set and start using a fresh set after your doctor gives you a clean chit.
Artificial tears or non prescription eye drops can also be used to relieve the itchiness and burning in the infected eye. If only one eye had been affected by conjunctivitis, do not use the same eye drop bottle for both eyes.
Eyes are the most important part of our lives. There are various branches of medicine which treat different aspects of the eye. Chief among them are-
Ophthalmology deals with the structure, physiology and diseases of the eye. On the other hand, optometry is a vision care science which involves the treatment and rectification of the visual system. Specialists emerging from these two schools of medicines are called Ophthalmologists and optometrists respectively. Though they both deal with the corrective measures and examination of healthy eyes, there are crucial differences between them.
Some of those differences are listed below:
Meaning: A specialist in surgical and medical eye problems, who performs operations in the eye is called an ophthalmologist. On the other hand, an optometrist is a specialist who has a degree in Doctor of Optometry (OD). He is not a doctor but a trained individual.
Area of Specialization: Both these specialists have different areas of specialization. An Ophthalmologist specializes in only vision and eye care. He/she has the necessary training to perform operations on the eye. On the other hand, an optometrist is not a doctor but a specialist who is involved in diagnosis, management and treatment of vision changes. He/she has the license to perform eye exams and tests and can prescribe corrective lenses.
Training: Both the specialists differ vastly in their training. An ophthalmologist is trained to treat all eye problems and is equipped to perform operations. He/she undergoes four years of medical school and one year of internship in any hospital. Optometrists on the other hand, after three or more years in college have to undergo four years of training before receiving a doctor of optometrist. (OD).
Headaches are common among working people as accumulated stress results in headaches and tiredness. Among the many different causes, strain on the eyes is one of the leading reasons for that annoying headache.
Taking an eye exam is recommended in case you are having headaches. The issues may not always be related to the eyes, but still a thorough eye check up is recommended. Strain in the eye is caused when small muscles present in the eye have to put in more effort than usual. Symptoms include aching, tired eyes with blurred vision and accompanying headaches. Such headaches are caused because of the following reasons:
This disorder is also called farsightedness. In case of this disorder, the images are focused by the eye behind the retina, and causes blurred vision and strain upon the eyes. Headaches occur as a result.
This kind of problem occurs when the lens hardens and becomes inflexible with old age. This makes it hard for a person to focus and causes sore eyes along with headaches.
All disorders or conditions of the eyes can be rectified with the use of prescribed spectacles and contact lenses. For people already having glasses, regular eye check up should be carried out. Your power may increase which you are unlikely to notice, so regular check ups are vital.
Headaches related to eye strain and eye problem can also develop from other causes. They are:
1. Glaucoma, an eye disease also causes headaches. This disease is characterized by the development of a fluid in the eyes, which in turn causes the internal eye pressure to shoot up. This pressure fluctuation can lead to headaches in many cases of glaucoma.
2. Cataract affected people suffer from headaches as well. Cataracts develop in individuals due to ageing. The lens becomes cloudy, and the vision gets blurred and slowly diminishes. The eye has to give more effort resulting in eye strain and accompanying headaches.
In case you are having headaches, and you are not being able to find out the reason behind it, you should have an eye check up. Eyes are very sensitive and added strain to them causes headaches. People who use computers for long hours are affected by headaches due to eye strain. The best prevention is to have an eye examination and switch to glasses or lenses if required.
Headaches are of various kinds and arise from different factors, but eye strain is known to cause a lot of headaches in people who do eye stress involving activities.
What is amblyopia or lazy eye? Amblyopia is decreased vision in one or both eyes due to abnormal development of vision in infancy or childhood. In amblyopia, there may not be an obvious problem of the eye. Vision loss occurs because nerve pathways between the brain and the eye aren't properly stimulated. The brain, learns to see only blurry images with the amblyopic eye even when glasses are used. As a result, the brain favors one eye, usually due to poor vision in the other eye. Another word for amblyopia is 'lazy eye'. It is the leading cause of vision loss amongst children.
The major causes of Amblyopia are as follows:
1. Eye Misalignment: The most basic reason for amblyopia is misalignment of the eyes. In case both your eyes are not aimed in the same proportion or direction, the image from the affected eye is turned off by the brain. Only the better eye functions. Double vision is restricted. The persistence of this defect for a prolonged time, makes the eye lose connection with the brain's visual cortex. Amblyopia develops.
2. Imbalanced error of refraction: If the refractive blunder of both the eyes is not the same, both eyes can't be in the center at the same time. Amblyopia happens when one eye stays out of the center since it is more myopic, farsighted, or astigmatic than the other. One eye becomes dominant. This results in the neglect of the unfocused eye, which neglects to associate with the mind. Treatment with glasses or contact lenses to adjust the refractive blunder of the eye is required.
3. Cloudiness in the visual system: Any kind of obstruction or cloudiness in the normal functioning of the eye tissues can be another reason, which leads to amblyopia. Disorder of any kind which blocks a clear image from being focused is capable of blocking the formation of a clear image on your retina. This may lead to amblyopia. This is perhaps the most severe type of this disease.
How can amblyopia be cured?
For treating amblyopia, a child must be compelled to utilize his affected, weaker eye. This can be done by correction of any disorder of the affected eye such as refractive error, problems in the retina, etc. The goal is to correct the amblyopic eye. The normal eye is usually covered up by a patch, so that only the affected eye can be used for vision. The patching up may continue for weeks, months or years until the best vision gets restored. The improving eye should be maintained well. Spectacles are also prescribed for correction of errors regarding refraction. Eye drops such as atropine are also used for blurring the vision of the good eye. Amblyopia makes you visually impaired. The earliest symptoms must be perceived and acted upon. In case you have a concern or query you can always consult an expert & get answers to your questions!
Contact lenses are one of the most convenient ways to correct vision related problems. It is easily disposable and requires the least maintenance. It might have minor side effects in the form of irritations and allergies but it requires the least time for adaptability. They help to correct nearsightedness and farsightedness along with astigmatism and age-related vision problems like presbyopia. Following are the benefits and harms of wearing contact lenses.
Positive effects of contact lenses
1. Better vision - Wearing contact lenses improves your vision to a great amount, especially peripheral vision. They are comfortable to wear and can correct both nearsightedness and farsightedness. They can cause discomfort initially but are more effective than glasses. Lenses are also available in bifocals and tints and can be worn for long periods of time.
2. Great for an active lifestyle - Glasses can be a hindrance to sports activities and can limit your peripheral vision. Lenses, on the other hand, are great for an active lifestyle as they require short adaptation period. They are easy to put and take care of and do not require a lot of maintenance on your part as it needs least cleaning.
Risks of wearing contact lenses
1. Dry eyes - Dry eyes are the most common side effects of wearing contact lenses
2. Infections - Contact lenses wearers are prone to infection of the cornea called keratitis. It can cause swelling, blurry vision and other problems due to lack of oxygen supply to the cornea. Infection can be prevented by maintaining the hygiene while wearing and taking off lenses.
3. Allergic reactions - Allergic reaction to the contact lens solution can affect your vision as it causes inflammation of the eyeballs and redness. It can also cause eyelid inflammation and limit your scope of vision.

A simple, uncomplicated cataract surgery should not take more than 10 minutes to perform. The best part about a cataract surgery is that most people see almost immediate results and improved vision. However, full recovery can take awhile. Each person heals at a different speed but ideally, your eyes should heal completely in a month. Here are a few tips to help speed up this process and avoid infections and eye injuries.
Take it easy
Just because the surgery takes a short time is no reason to underestimate its importance. Do not drive on the first day and as far as possible avoid driving for the next few days as well. Do not put any extra pressure on your eyes by bending, lifting weights etc. This will ensure that your stitches do not tear open. Try to avoid excessive sneezing and coughing as this can jerk the lens out of place.
Protect your eyes
Wearing sunglasses is a good idea after a cataract surgery. This will protect your delicate eyes against dust, wind etc. Avoid using community swimming pools and hot tubs immediately after such a surgery to lower the risk of infections. Avoid rubbing your eyes aggressively. For the first week, keep your face out of the shower so as to avoid feeling the need to press or rub your eyes as well as to protect them from bacteria in the water.
Your eyes may feel dry and scratchy after a cataract surgery. This is normal and not something to worry about. Your doctor will prescribe eye drops to be taken after the surgery. Use these regularly. Once this is over you may need additional artificial tears or lubricating eye drops. However, do not take these drops without first consulting your doctor. If your eyes are sensitive to the preservatives in bottled eye drops, look for single use ampoules. Ensure that you always wash your hands well before administering the eye drops.
Keep the eye clean
Though washing your face is avoidable, you must still keep the eye clean. Use cotton and a sterile saline wash for the first few days. You can later replace the saline with cool boiled water.
If you feel any deterioration in your vision, pain or excessive discharge in the operated eye, you must immediately consult your doctor. Seeing sudden flashes of light or floaters in your vision should also not be ignored.
We are surrounded by light from everywhere on all sides. Wherever we go, there is some source of light, be it natural or man made. However, exposure to bright light in excess can cause strain to your eyes and if this is continued your vision quality might decrease.
Here are some ways you can adjust light in order to lessen eye stress and to increase your visibility.
Make adjustments in your workplace
According to studies, it has been shown that half of people who work in front of computer screens every day suffer from eye strain. Not only the computer, but the entire lighting around your workstation may also be causing damage.
1. Reduce the brightness of interior lights. Many offices have bright, fancy interior lighting. Use of light bulbs and fluorescents should be lessened.
2. In case of the presence of a window right behind or in front of your work desk, more strain is imposed upon your eyes because of the reflections on the screen. You should change the place or use dark, thick curtains or coat the glasses with anti-reflective material in order to reduce the glare.
3. The blue light emitted from the computer causes a great amount of eye strain. You should adjust the brightness and keep it as low as possible.
Improve your home lighting
For people who spend a lot of time at home working, adjustments should be made to the lighting in order to reduce eye strain.
1. Avoid reading in a dim light room. This can give you headaches and produce eye strain. Any kind of activity where a lot of focus is required in dim or poorly lighted environments causes damage and strain to the eyes.
2. Use desk lamps, reading lamps, under cabinet lights in the kitchen and other types of lights everywhere you work.
3. If you work in a place for more than an hour, a nearby light would make it less stressful for the eyes.
For people with low vision.
1. For people with less power of vision, proper lighting is a must. A 60-year old man would need to double the amount of light to carry out any activity which a man of 30 years would require.
2. People having disorders such as macular degeneration, glaucoma and similar vision disorders need advanced lighting and should consult a doctor for ideas on improving their home lighting.
The presence of proper lighting improves our concentration, our ability to read, and we can differentiate between colors better. Therefore, always opt for the best lighting to avoid giving stress to your eyes. In case you have a concern or query you can always consult an expert & get answers to your questions!
Eye twitching, tics in the eyelids and spasms in the eye are pretty common. In case of eye twitching, usually the lower eyelid becomes involved. The upper eyelid may also twitch in certain cases. Twitches are not permanent in nature, and they leave after some time. In some cases, eye twitching may last for long durations of time such as weeks or months.
Eye twitching is not a critical medical condition. It is a temporary prickling and irritation in the eyes, which ceases after some time. Common twitching of the eyes is not related to any neurological disorder.
Here are some reasons which cause eye twitches-
Every individual goes through some amount of stress, and the body reacts differently in different people as a result of stress. An eye twitch may be caused due to stress, especially related to strain in the eyes.
In order to reduce stress you should practice yoga, meditation, perform breathing exercises and take a break. Reducing the stress would also cease the twitching in the eyes.
Eye twitching can appear when you are fatigued or very tired. Lack of proper sleep makes your body tired, and this might trigger eye twitching.
You should improve upon your sleeping hours and sleep more.
Vision problems and any issue related to the eyes can cause stress, which may result in constant twitching in your eyes. Whenever too much stress is imposed upon your eyes, they tend to react and twitching occurs. Any problem would make the eyes put in more effort, which results in strain.
You should have an eye check up if you experience an eye strain accompanied by twitching sensation in your eyes.
People who use computers, laptops, tablets and smartphones for a profuse period of time experience pain and twitching in the eyes. There is a 20-20-20 rule to be followed while using such devices, which reduces eye strain and reduces itching or twitching. You can also avail special eyeglasses for people who spend a lot of time on computers.
Intake of an excess amount of caffeine leads to eye twitching. Cut down your doses of coffee, tea, dark chocolates and soft drinks in case of eye twitching and you may observe an easing in the twitching.
Alcohol also leads to eye twitching so you must abstain from alcohol in case you are having twitching in the eyes.
This disorder develops in people who have crossed the age of 50. People who use computers a lot also develop dry eyes, which leads to eye twitching.
Our eyes twitch because of a lot of reasons. You should know the facts right and avoid situations that lead to eye twitching.

Eyeglasses and contact lenses are both used for vision correction. Both of the options have their advantages and disadvantages but a number of factors like lifestyle, comfort and age etc. are important while deciding which one to choose. Here is a list of the fundamental differences between using spectacles and using contact lenses:
- Distance from the cornea: Lenses are worn directly on the eye and are in constant physical contact with the cornea while glasses are worn over the eyes.Contact lenses may cause infections in the eye because the user has to touch the eye in order to wear them and to take them off.
- Difference in vision: Since the lenses of the spectacles are a little distance away from the eye, vision can be slightly distorted but contact lenses can provide natural and accurate vision. Also, side vision is not improved by glasses as you have to turn your head to see what is beside you. The contacts move around with your eyeballs and the peripheral vision is in focus.
- Ease of use: Some people find eyeglasses difficult to use because of the constant weight on the face and the obstruction caused by the frames of the glasses. There may also be a constant need to adjust the frames. Often eyeglasses slip down the nose when you sweat or engage in the rigorous physical activity. Contacts are free from all these hassles- they not distracting or obstructive and so they are extensively used by dancers and athletes. Spectacles are very uncomfortable to wear during the rains or in humid weather because they fog up.
- Infections and complications: Contact lenses can get displaced inside the eye and they can be difficult to reposition. They also cause the eyes to itch and water if you wear them for a very long time at a stretch or if tiny dust particles enter your eyes. The use of eyeglasses is far more flexible in this respect- they can be removed in case your eye itches or burns, but regular use of glasses causes dark circles and bags under the eyes.
- Aesthetic differences: People often prefer contact lenses as they do not change the physical appearance- they help you to look natural and you can also use colored lenses to change the color of your eyes. Glasses may look slightly unnatural but some people also prefer them for the fashion quotient.

Colour blindness is not a type of blindness at all; it is an insufficiency in the way some people see colour. Once afflicted by this vision problem, people face difficulty in distinguishing specific colours like red, green, blue or yellow. So to call it colour vision deficiency would be much appropriate, and it hits men more often than women. In a report by Prevent Blindness America, it is revealed that about 8% of males and less than 1% of females are affected with colour vision problems. Generally, red and green colour deficiency is the most commonly found. In very rare instances, a person may carry a trait which lessens his ability to distinguish between blue and yellow colours. This blue-yellow hue insufficiency normally is found in men and women equally.
Understanding signs and symptoms: Do you have any difficulty in seeing yellow, green or red colours? Do people often tell you that you are seeing the wrong colour? If so, then these are key signs that you are affected with a colour perception deficiency. Quite opposite to popular belief, hardly a colour blind person is able to see only the shades of gray. Most people who are deemed as colour blind are able to see shades but cannot distinguish between one colour and another and get easily confused with other shades, depending on the kind of colour blindness they are affected with. If you have suddenly developed a colour vision deficiency when you were able to view and distinguish all the shades previously, then you should visit an ophthalmologist without further delay.
Causes behind colour blindness: Colour blindness takes place when the light-sensitive cells within the retina stop responding accurately to variations in wavelengths of light.
Photoreceptors present in the retina are termed as rods and cones. Rods are present abundantly, and about 100 million rod cells are present in human retina and these cells are very sensitive to light, but rods are impervious to sunlight and therefore, are incapable of perceiving colours. The cones, on the other hand, are responsible for our understanding of different colours. There are three types of cones, each of which is responsible for perceiving red, green and blue light. The three cones work together to help us see the whole range of colours. People who are colour blind usually have faults in a particular cone cell, which makes them unable to distinguish that particular shade.
Combatting colour blindness: Gene therapies are reported to cure colour blindness in monkeys, as per the reports of a study conducted by researchers of the University of Washington and Florida in September 2009. While early methods appear promising, gene therapy is not considered effective for human beings unless the treatments are verified to be safe.
Hence there is no effective means of curing colour blindness, but there are some strategies that may aid you to function better. However, if you are into graphic designing or anything that requires handling of different colours, then you will need professional help. The sooner you become aware of your insufficiency, the better you can compensate for it.
Some people also use contact lenses or eyeglasses that act as filters to enhance colour perception. If you are affected by this problem, make sure you visit an eye-care practitioner for detailed advice.
