Cataract is generally associated with old age. However, in some unfortunate cases, children could be affected by cataract as well. A cataract can be defined as a cloudy or opaque layer that forms on the eye's natural lens that lies behind the iris and the pupil, leading to eventual loss in vision. Cataract can affect children in one eye or both eyes.

Cataract can be a congenital birth defect or can develop as the child grows older. The latter case is known as pediatric cataracts. The exact cause of cataracts in children is not known, but it has been associated with a number of genetic disorders, low birth weight and infections during pregnancy. Traumatic events such as an injury to the eye can also cause cataracts.

The earlier a cataract is diagnosed and treated, the better it is. It is easier to identify a cataract that affects both eyes than a cataract that affects only one eye. If a congenital cataract is not treated in time, the part of the baby's brain used for sight may not develop properly. Hence it is crucial to recognize cataract symptoms.

Here are a few you should look out for:

    Not looking directly or responding to large, colourful objects.
    Not being able to find small objects while crawling.
    Excessive squinting or shielding their eyes to bright sunlight.
    Eyes that do not focus on the same point.
    White reflex instead of a red reflex in photographs.
    Uncontrolled movement of the eye.

Cataracts that are too small to affect sight can be treated with eye drops to dilate the pupil. However, this provides only temporary relief. Surgery is the most preferred form of cataract treatment. This surgery can be performed even in the first few weeks of a baby's life. The child is put under anesthesia and a microsurgical instrument is used to break the lens into small pieces and remove it.

This surgery is followed by the use of lenses or glasses to help the eye regain its power to focus again. In some cases, the lens may be implanted to replace the natural lens. In cases where cataract affects only one eye or one eye is more severely affected than the other, there may be a tendency to develop amblyopia or lazy eye syndrome. In such cases, it becomes necessary to patch the good eye shut and stimulate vision in the eye that has undergone surgery.

Eyes are one of the most important organs of the body, and the scorching summer heat can cause serious eye problems like conjunctivitis, infections, red eye, migraines etc., which is why it's important to take proper care of eyes during the summer season.

8 Tips to Keep Your Eyes Cool in Summers

4 tips for a great eyesight

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).




4 Tips for a Great Eyesight

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:

1. 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.

2. Difference in vision
Since the lenses of 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.

3. 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 rigorous physical activity. Contact lenses are free from all these hassles - they are not distracting or obstructive and so they are extensively used by dancers and athletes. Spectacles is very uncomfortable to wear during the rains or in humid weather because they fog up.

4. 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.

5. Aesthetic differences
People often prefer contact lenses as they do not change the physical appearance - they help you 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.

Lens Vs Specs

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

78% of urban youth are in front of the computer screen/ mobile screen for about 12 hours a day. Such extensive strain to the eyes can have long term effects on vision.  Act now to protect your eyes by following these tips-
