The most common vision problems are shortsightedness and farsightedness. Shortsightedness is when a person sees close objects clearly while distant objects appear blurry. It is more common than farsightedness and affects about 70% of the Asian population.

When there is a refractive issue, the prescription usually has a plus/minus with it and also a number. A  minus  symbol is used to represent shortsightedness; the greater the number of the glasses, the higher the shortsightedness. High myopia is a more severe form of shortsightedness where the power is -6.0 or higher.

Symptoms: 

As mentioned, the person will be able to see nearby objects but will have difficulty seeing far off objects.

Difficulty reading signs and boards
Squinting
Straining to reduce the strain on the eye
Tired and fatigue due to this eye strain, especially when in constant move like playing sports or travelling
How it happens?

Vision can be explained by a physical process where light passes through a lens and falls on the retina in the posterior portion of the eye where it forms an image. This is then sent to the brain where it is read and interpreted as a particular object. When the lens becomes elongated, the image that is formed is distorted in that it is formed in front of the retina and not on the retina. Though it gradually settles down with adulthood, in most cases, it progresses and requires corrective lenses. The corrective lenses ensure the image falls on the retina and visual perception is improved.

Treatment:

Corrective glasses are the most commonly used measure for nearsightedness. The lenses could be used either as spectacles or as contact lenses.
Laser surgery can also be used to correct the problem. A thin layer of the cornea is removed and the image formation is corrected.
Artificial intraocular lenses are also being used to treat this condition. They work like contact lenses and may need periodic replacement.
The most common technique, especially for high myopia is the use of surgery to correct the problem. This is a one-time correction and is a more durable solution than the earlier mentioned options.
Appropriate calculations are done to identify the lens to be used so that proper vision is restored.
Complications: 

Though not common, retinal detachment and variable postoperative refractive error can occur during the surgery.
It is very important to set realistic expectations with the patient in terms of what to expect before, during, and after surgery. If only one eye is going for repair, the chances of mismatch in vision could be present in the early stages. Being clear about what to expect will help in successful correction.

Myopia or Nearsightedness - How It Can Be Treated?

Swelling of the conjunctiva membrane due to an infection is called conjunctivitis. It can affect one or both eyes. The blood vessels get inflamed and the eye looks red or pink. Pink eye is the common name of conjunctivitis.

Symptoms

The symptoms of conjunctivitis are very obvious:

The white part of the affected eye appears reddish because the membrane which is affected is a layer that covers the white.

The affected eye is extremely itchy.

The eyelids get swollen.

It is painful, especially when the surroundings are bright.

A crusty layer may or may not form during sleeping and it can make it difficult to open the eye.

The infection typically affects one eye first and catches on to the other eye within a day because it is highly contagious. People in contact with the affected person are highly susceptible to contracting the infection.

Causes

This highly contagious infection is painful and itchy and needs immediate attention. The treatment is the same no matter what the cause. The main causes are:

Bacterial infection (indicated by sticky secretion).

Viral infection (indicated by a watery secretion).

In infants, it can be the cause of a partially opened tear duct.

Sometimes it happens due to an allergic reaction.

A Chemical reaction.

Immediate Action

Before going to a doctor and getting medicines, some immediate steps must be taken. Here are some things to do to reduce the discomfort and prevent the infection from spreading.

Contact lenses must be removed to prevent further infection. Infected contact lenses must be discarded or disinfected.

Contact with other people must be avoided. Direct physical contact, using the same towel or eye products must be avoided.

Avoiding touching the unaffected eye, it might prevent infection of the second eye.

Using a lukewarm compress can relieve some of the pain.

Using an over-the-counter hydrating eye drop can relieve some of the itchiness and the annoying sensation of having something in the eye.

Treating Conjunctivitis in Ayurvedic Way

Antibiotics have a lot of side effects and it does not sit well with some people. This is why a more natural approach is recommended. Ayurveda helps treat all the symptoms with zero side effects. Ayurvedic treatment is effective because it has everything needed:

Anti-inflammatory properties.

Antioxidants.

Antibacterial properties.

Ayurvedic treatment always works for conjunctivitis and does not cause any side effects. It is best to prevent getting infected altogether though. Using fresh sheets, fresh towels, disinfected eyewear and avoiding touching the eyes before disinfecting the hands can help.

Take Away

Conjunctivitis is one irritating eye infection which is contagious in its nature. However, it can be cured with proper care and ayurvedic treatment. It is always advisable to consult an ayurvedic specialist before going for any of the ayurvedic treatment.



Conjunctivitis - How Can Ayurveda Help?

Amblyopia or Lazy eye is the eye condition in which vision is reduced and cannot be corrected with glasses or contact lenses. All the images seen by the amblyopic eye are not fully acknowledged by the brain. It always affects only one eye, but may be accompanied with reduction of vision in both eyes. It can cause loss of vision, including loss of depth perception and two-eyed 3D vision. It's treatment can yield improvements at any age, but early detection can offer the best chances for a cure. Recent research has proven that lazy eye treatment can be successful in older children and adults. Comprehensive vision examinations are required for infants, toddlers, and pre-school children for the detection of lazy eye or amblyopia.

When the brain parts related with visual processing do not function properly, problems arise with such visual functions as the perception of movement, depth perception and fine detail (acuity, clear eyesight and sharp vision). Amblyopia is the most prevalent neurological defect of vision in children and adults resulting from developmental problems in the brain. Any interference with clear vision in either eye during the first six years or 'critical' period of visual and brain development can cause a lazy eye.

Constant strabismus or the constant turn of one eye in any direction, be it inward turn or crossed eye is one of common causes of amblyopia. The differences in vision or it's prescription between the two eyes leads to refractive amblyopia. Sometimes congenital disorders or a physical blockage of an eye due to trauma, drooping lids, cataract or a blocked tear duct can also lead to amblyopia. Many parents and children are not aware of any symptoms, as amblyopia usually occurs in one eye only and a lazy eye condition can exist without a noticeable eye turn. The visual acuity tests in addition to the 20/20 eye test charts and eye examination with cycloplegic drops by ophthalmologists are necessary to detect lazy eye.

Vision therapy for the eyes and brain is a highly effective non-surgical treatment for lazy eye. It is a progressive program of vision exercises customized to fit the visual needs of each patient. It is conducted at the clinic and occasionally supplemented with exercises to be done at home or workplace. It improve visual comfort, ease, and efficiency and change how a patient processes or interprets visual information. When considering treatment options, it is important to understand that lazy eye results from neurological deficit or problems in the brain and surgery for lazy eye is performed on the muscles on the outside of the eye. Most of the cases, lazy eye surgery provides cosmetic benefits and does not improve the patient's vision, hence options for vision improvement should be exhausted before eye muscle surgery is considered.

Lazy Eye or Amblyopia - Symptoms and Cure

Blurred vision is most often a sign that you need corrective spectacles for near sightedness, far sightedness or astigmatism but it could also be a sign of a bigger problem including eye diseases or neurological problems. Blurred vision involves the loss of sharpness of vision and objects appearing hazy and out of focus. It can affect one eye or both eyes simultaneously.

Whatever be your age, it is a good idea to consult a doctor as you begin to experience a blurred vision. To measure the extent of your vision problem, a doctor will do a comprehensive eye examination including spatial contrast sensitivity and a standard eye chart test. Some of the factors that trigger blurred vision are:

1. Myopia or nearsightedness
2. Hypermetropia or farsightedness
3. Astigmatism caused by an irregularly shaped cornea
4. Presbyopia - the diminished ability to focus on objects due to the hardening of the lens in the eye
5. Dry eyes or the lack of lubrication on the surface of the eyes
6. Hormonal changes during pregnancy
7. Migraine headaches
8. Temporary floaters in the eye formed by the liquefying of the gel in the eyes
9. After effects of lasik surgery
10. Eye drops or medication
11. Overuse of contact lenses
12. Diabetes

Blurred vision can also be a symptom of a serious condition such as cataract, glaucoma, macular degeneration, diabetic retinopathy and cardiovascular diseases.

Treatment for blurred vision depends on the factors triggering it. Wearing corrective glasses can cure blurred vision caused by myopia, hypermetropia and astigmatism. These conditions can also be treated by lasik surgery. For blurred vision related to diabetes, check your blood sugar and get it into its optimal range.

Exercises for the eye muscles can also help sharpen vision and lower the rate of eye muscle degeneration. Some of these exercises are:

1. Alternately focus on an object close to you and another far from you for ten seconds each.
2. Blink your eyes and hold for two seconds
3. Roll your eyes clockwise and anticlockwise. Repeat 15-20 times.
4. Rub your palms together to generate heat and place over your eyes to relax them.

A healthy diet with plenty of vitamin a can help keep your eyes healthy and prevent blurring of vision. Wearing sunglasses can also protect your eyes from harmful uv radiation and lower their rate of wear and tear. Lastly avoid reading in moving vehicles and holding a book too close to your face.

Is Your Vision Blurry? What Should You Do?

Amblyopia is decreased vision in one or both eyes due to abnormal development of vision in infancy or childhood.It is commonly known as lazy eye, in which a child's vision does not develop properly, usually in one eye. If it is left untreated, a child's vision will never develop correctly in the affected eye.

What are the types of Amblyopia are there?
There are several different types and causes of Amblyopia, such as Strabismic Amblyopia, Deprivation Amblyopia and Refractive Amblyopia.
The end result of all forms of Amblyopia is reduced vision in the affected eye(eyes).

How does Lazy Eye occurs?
Lazy eye occurs when your brain favors one eye, often due to poor vision in your other eye. Eventually, your brain might ignore signals from your weak or lazy eye. The condition can result in vision impairment and loss of depth perception.

What are the Symptoms of Lazy Eye?
Lazy eye may be hard to detect until it becomes severe. Early warning signs include:
1. Tendency to bump into objects on one side
2. An eye that wanders inward or outward
3. Eyes that appear not to work together
4. Poor depth perception
5. Double vision
6. Squinting

What Causes Lazy Eye?
A number of conditions and factors can lead you to rely on one eye more than the other. These include:
1. Constant strabismus or turning of one eye
2. Genetics or a family history of lazy eye
3. Different levels of vision in each of your eyes
4. Damage to one of your eyes from trauma
5. Drooping eyelids
6. Vitamin A deficiency
7. Corneal ulcer or scar
8. Eye surgery
9. Vision impairment, such as nearsightedness, farsightedness, or astigmatism
10. Glaucoma, which is high pressure in your eye that can lead to vision problems and blindness

How is Amblyopia diagnosed?
When it first occurs, parents and children often don't notice the condition. It's important to get routine eye exams as an infant and child, even if you show no outward symptoms of eye problems.
Family history of amblyopia is a risk factor for the condition.

How Is Lazy Eye Treated?
Glasses/Contact Lenses
Eye Patch
Eye Drops
Surgery
Other treatments include:
Atropine penalization therapy (also used for maintenance)
Optical blurring through contact lenses or elevated bifocal segments

What Is Amblyopia? Are You or Your Child Suffering From It?

With technology at your fingertips, it is hard to think of times when the existence of laptops and television sets was unimaginable. Technology is common enough to be taken for granted in present times. TV and laptops are especially in widespread use. The primary reason could be entertainment, an urge to connect to the larger world, or the need to kill time. Such dependability leads to severe health hazards. Read on to find out more:

Effects of TV and laptops on your health:

    Sleep deprivation: Long hours of exposure to artificial light can lead to sleep deprivation.
    It can also lead to serious vision problems: Watching TV or using laptops for long hours can make your eyes vulnerable to constant glare. You fail to realize, but changing lights of a computer screen or of a television set in a dark room can be extremely strenuous for your eyes to adjust. Constantly changing lights can lead to glaucoma. However, dry and itchy eyes, headaches and poor vision are the commonly noticed effects.
    It causes obesity in children and adults: Since all your work can be done on the internet, you tend to become lethargic. You are too lazy to go to the market or to the bank. Even if you are not watching you use the television for background music. Adults therefore do not make qualitative use of their free time. Children are addicted to playing games and browsing sites on the laptop. They hardly indulge in outdoor games. This leads to obesity in adults and children all the same.
    Propels your desire to eat fast food or packaged food: Binge eating is a very common practice while watching TV or using laptops. Chips, pizzas, burgers, ice- creams, cold drinks and absolutely anything junk devoid of nutritional value are more liked by us. Junk food not only leads to weight gain but is also detrimental to our digestive system.
    Can increase the risk of infertility in men: Laptops heat up when used for a long span of time. This heat can increase scrotum temperature which results in reduced sperm production, leading to infertility.   

As is said, nothing in excess is good for your health. It is therefore, best to make controlled use of TV and laptops to avoid its harmful effects.
