LASIK stands for Laser In-situ Keratomileusis. This is a common eye surgery that helps in correcting vision problems. During this procedure, the cornea of the eye is cut across by a medical expert to raise the tissues and reshape them to correct vision. LASIK is suitable for patients who have shortsightedness, long sightedness or who suffer from astigmatism.
Here are the 5 benefits that a LASIK surgery offers:
1. Improved vision - A study reveals that 95% of the people who underwent this surgery achieved uncorrected visual acuity of 20/40 and 85% of the people achieved 20/20 vision. This procedure ensures that a patient achieves enhanced vision.
2. Quick results and recovery - This surgery enables you to return to your normal schedule immediately the day after the surgery. You can have clear and improved vision within a day.
3. Long- lasting outcomes - A minimum timeframe of 3 months is required for the eyes to adjust, after which LASIK results are permanently noticeable in a patient. No follow up procedures are required unless something wrong went with the surgery. The patient will continue to have improved vision unless there is any normal loss due to illness or aging.
4. No need of glasses - You no longer require glasses as your vision turns to normal post-LASIK surgery.
5. Goodbye contact lenses - LASIK surgery will help eliminate the need for contacts. You will be able to avoid all the problems pertaining to wearing a contact lens, including lens solution.

Cataract can be defined as the clouding of the natural lenses in the eyes. This is caused by the clumping of protein in the eye lens. Cataract is a common eye disorder and the leading cause of loss of vision in people who are past their fortieth birthday. Cataract can occur in one or both eyes. When diagnosed properly, cataract can be treated with surgery to prevent blindness.
Depending on where and how they develop, there are many types of cataract. The most common amongst these are:
- Subcapsular cataract: These occur at the back of the eye lens. Diabetic patients are very susceptible to this kind of cataract.
- Nuclear cataract: Yellowish-brown cataract that form in the center of the lens are called nuclear cataract. This is usually seen in cataract caused by ageing.
- Cortical cataract: Cataract in the lens cortex are known as cortical cataract. These are wedge shaped and whitish in color. Spokes protruding out of these opaque wedges can be seen moving towards the center of the eye.
- Congenital cataract: Though they are not common, babies can also have cataract. Cataract formed at birth or within the first year of a baby's birth are known as congenital cataract.
- Secondary cataract: Cataract is one of the known side effects of diabetes and glaucoma. Some steroids and medicines are also linked to cataract.
- Traumatic cataract: If your vision becomes cloudy years after an eye injury, it could be a traumatic cataract. It can take several years for this to happen.
- Radiation cataract: Exposure to radiation can also lead to cataract. This is seen sometimes in patients who have undergone radiation therapy to fight diseases like cancer.
Though the type of cataract might differ from person to person, the symptoms are usually the same. Some of the common symptoms of cataract are:
1. Blurred vision
2. Reduced night vision
3. Increased sensitivity to light and glare
4. Seeing halos around lights
5. Colors appearing faded
6. Double vision
A reading test is the first step towards diagnosing cataracts. This is followed by tests to measure the eye pressure. Your doctor will also need to dila te the pupil to check the condition of the optic nerves and retina. Surgery is the safest way to remove a cataract. Surgery is usually recommended when cataract begin inhibiting your daily life such as preventing you from driving, interfering with reading etc.
In most cases, this can be done as an outpatient procedure. The earlier it is diagnosed, the easier it is to treat. Hence, if you notice any of the symptoms mentioned above, get your eyes checked at once. The surgery is a day-care surgery only, so a person can go home the same day.

An important organ of the body, eyes must never be taken for granted and need to be protected at all times. In addition to protecting them, you also need to improve as well as maintain their overall health.
Here are some of the ways of keeping your vision in top form:
1. Eat for good eye vision
To have healthy eyes and consequently good vision, you need to have foods that keep them in good health. Nutrients like Zinc, Vitamins C and E and Omega-3 fatty acids can help to fend off age-related sight problems such as cataracts or macular degeneration (a condition characterized by the deterioration of the middle portion of the retina). Foods like eggs, nuts, green leafy vegetables, oranges and citrus fruits are what you need to have to get good eye health.
2. Kick the smoke habit
Smoking can adversely affect your eye health and can make you prone to eye conditions like cataracts, macular degeneration and damage of optic nerve (a nerve that transmits impulses from the eyes to the brain). By kicking this habit, you end up saving your eyes from irreversible damage.
3. Use sunglasses
Exposure to the sun’s ultraviolet rays for a long period of time can make you prone to common eye problems including cataracts. To protect them from the sun’s harmful rays, you need to use sunglasses that block 99-100% of ultraviolet A (UVA) and ultraviolet B (UVB) rays.
4. Go for a regular eye checkup
Going for regular eye examinations can help in protecting your vision and ensure you see clearly. Eye examinations are important to help you find eye problems like glaucoma (a condition wherein the optic nerve is damaged, resulting in vision loss). A comprehensive eye examination can help in identifying problems like nearsightedness, farsightedness or astigmatism (an eye defect that occurs to a deviated spherical curvature). In case you have a concern or query you can always consult an expert & get answers to your questions!
Diabetic retinopathy is an eye problem that affects the retina of the eye and causes total and irreparable blindness. It usually occurs after 15 to 20 years of diabetes. Poorer the control earlier is the onset. Association of hypertension and increased blood cholesterol make the condition more serious.
In initial stages, there may not be any visual symptoms. Some patients may get macular edema marked with a decrease in the vision without exhibiting diabetic retinopathy.
Here is some important aspect of the disease that you should know:
Symptoms as the condition progress: you might experience blurred or fluctuating vision, impaired color vision, spots or dark strings floating in your vision, dark or empty areas in your vision and an even significant decrease in vision which is not corrected with glasses. Diabetes can cause early cataract formation (diabetic cataract) in the eye.
Causes: In an uncontrolled diabetic patient, the blood supply to the retina is decreased due to vascular constriction, in due course of time. This causes anoxia which promotes new vessel formation which may leak causing macular edema and or exudates. The newly formed vessels are fragile, can cause small projections (aneurysms) or may bleed. This all happens in the most sensitive central part of the retina (macula) thereby affecting vision to varying degree.
Advanced diabetic retinopathy: more edema, exudates, and hemorrhages occur. The newly formed vessels may profusely bleed in the cavity of the eye, seriously affecting vision. In due course of time, retinal fibrosis occurs which may cause retinal detachment and total blindness. Few eyes may develop an increase in intraocular pressure (glaucoma) at any stage of the disease, causing blindness even without advanced diabetic retinopathy.
When does the risk increase: longer the duration, higher the incidence. If you have an uncontrolled blood sugar ideally evaluated by hb1ac (glycosylated HB) test, hypertension and increased cholesterol. Pregnancy too increases the risk. Ethnicity plays an important role. More prevalent in native Americans, Hispanics and Africans and now some studies highlight incidence in southeast Asia, including Indians.
When should you consult ophthalmologist: once you are declared diabetic, you must consult an ophthalmologist. Thereafter as per his advice every one or two years or even early if your control is poor or if your parents suffered from advanced diabetic retinopathy. If you are pregnant, eye examination may be needed frequently. Remember, proper control of risk factors and timely examination and intervention can prevent you from becoming blind. A Recent introduction of oct evaluation & intravitreal therapy has significantly helped patients with diabetic retinopathy.

Do you know that every little activity that you perform on a daily basis impacts your body? what you eat, how long you sleep and even every tear you shed affects your body. Most people are aware of how their body reacts to major activities, like exercising, but few are aware of how the body reacts when they cry.
While you are generally concerned with the mental cause and effect of crying, have you thought about what crying does to you physically? tears are not always shed when a person is upset. Tears are a body's way of expressing itself as well as protecting itself. Everything from a happy ending in a movie to a dust particle in the eye can make you tear up.
There are essentially three kinds of tears. Basal tears and reflective tears help keep the eyes lubricated and irritant free respectively. It is the psych tears, which we commonly refer to as crying, that come as emotional responses.
Crying might be a sign of emotional stress and pain but if you are wondering how it harms your body, the answer is that it does not. Crying does not harm one's body physically. In fact it does better than harm to your body, purely physically speaking. Here's how-
- When you cry, your tears help your eyes remain clear.
- It also has anti-bacterial properties that keep your eyes clean.
- Your eyes remain properly hydrated thus reducing any kind of irritation. You might feel dehydrated after a while due to the loss of water and salt.
- Even the excess manganese in your body gets washed out through tears.
But for some, the act of crying can cause medical complications. It can lead to fits or can cause an acute shortness of breath. For those with severe heart conditions, there can be a cardiac pain. Crying can take a toll on your body if you have certain medical conditions. For most people crying does more good for their body than harm.

Causes and Symptoms of Hypermetropia You Need to Know About
Hypermetropia, commonly known as long-sightedness, is a common vision condition in which distant objects appear clear, but nearby objects seem blurry or foggy. A person's ability to focus is greatly dependent on the degree of farsightedness. This condition of the eye is usually observed at birth and is also hereditary to some extent. Although, contact lenses and eye glasses are common methods of treatment, surgeries are also an option.
Before getting to understand the causes one should be aware of the structure of the eye.
The eye has two parts that focus on images
- The clear surface at the front of the eye known as the cornea
- The second part is the lens, which is a clear structure
In a normal eye, these clear surfaces have a smooth curvature. The cornea and the lens bend or refract the incoming light to direct a sharply focused image on the retina, situated at the back of your eye.
Hypermetropia is caused when
- The cornea or lens in the eye is not even or smoothly curved. In such cases, light rays are focussed behind retina which gives a blurry vision.
- The condition can also occur when the cornea of the eye is not curved enough. A shorter than the normal eye can also lead to such a condition. Convergent squint with eyes turning in is common in hypermetropes.
Due to these factors, the image is not precisely focused on the retina, causing blurry vision for nearby objects.
Some of the symptoms of farsightedness include:
- Objects that are close may appear blurry or cloudy
- Squinting the eyes might be necessary for viewing clearly
- A person may experience strain in the eye, aching and even inflammation in and around the eye
- Prolonged periods of close task like reading, writing or drawing may cause discomfort in the eye or minor headaches
Chronic eye strain and cross eyes are some of the commonly observed complications. In case you have a concern or query you can always consult an expert & get answers to your questions!
Ebooks maybe are a lot easier to carry, and with the emerging trend of Kindles, it may appear to be more convenient than paperbacks, but the smell of new books, the texture of its pristine pages, is unparalleled to the inanimateness of ebooks. But that is not just why you must choose paperbacks over ebooks.
Read on to find out why paperbacks work well over ebooks for better eye health.
- Does not involve light-emission: The backlit electronic devices, strain your eyes, causing redness, irritation and watering. Most doctors advise that exposure to light during the evening, especially from artificial sources should be minimal. On the other hand, books do not emit any harmful rays, making it the obvious choice if you want to take good care of your eyes.
- Do not hamper body clock: Our system has a tendency to adapt itself to the rhythm of life by responding to the surrounding light. However, the blue light in reading devices disrupt the release of melatonin or the sleep hormone, causing inadequate, less deep sleep, and fatigue and irritation the following morning. Thus, not giving enough time to your eyes and body for revitalizing. On the other hand, studies have shown that people reading books sleep better and timelier than those reading on devices.
- Proximity to device not required: The admonition of not sitting too close to the television's screen glare is nullified by reading devices where a certain level of proximity is required for comfortable reading, which harms our eyes. But paperbacks do not have any such risk involved as there is no glare that would affect our eyes.
- Does not induce disrupted winking: Electronic devices often trigger a tendency to not blink and stare at the screen constantly for longer than advisable. That does not give the lenses in your eyes the momentary rest that the eyes require in order to replenish themselves.
Exercises to improve eye health
There are many common measures people take to improve their eyesight or improve their vision. These include wearing glasses, lenses, sunglasses and many such measures. Here are some effective exercises which prove to be highly beneficial in increasing your eye health:
- Stretching: This is the most common and also one of the easiest to do. It requires you to just look up, hold for two seconds, look down, hold for two seconds, then repeat this procedure for each corner of your eye, which means top-left, top-right, bottom-left and bottom-right corners.
- Flexing: This is simply rotating your eyes in circles. Roll your eyes in the clockwise direction for one minute and then roll your eyes in the anticlockwise direction for one minute.
- Focus switching: This particular eye exercise is used for accommodation and is probably the most useful one. In this eye exercise, you have to hold something at a reading distance and cover the other eye. You then have to find something that is at least twenty feet away and trace its shape with one eye closed. With one eye closed, trace more shapes which are twenty feet away and this may improve your eyesight.
- Palming: This exercise is also very simple to perform. All you have to do is cover your eyes with your palms. Once you have done this, just wait and see that there are no bright flashes of light. If you see that there is a bright flash of light, just wait till they go. This is used primarily to destress the eyes.
- Deep blinking: This is also an incredibly useful exercise for distance vision. All you have to do is to place some large letters at a fair distance and then sit on a chair. You have to then close your eyes and tighten all your muscles for 5 seconds. After the gap of 5 seconds, open your eyes and see the letters for a second or two. The more time you do this the more clearly you will be able to see the letters after reopening your eyes.
Finally, a warning has to be given that these eye treatments are not universally accepted by all doctors. In case you have a concern or query you can always consult an expert & get answers to your questions!
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. In case you have a concern or query you can always consult an expert & get answers to your questions!
