Amblyopia is commonly known as'lazy eye. It is a vision development disorder, which affects eyes and the brain during infancy and childhood. It signifies that the eye does not achieve a normal visual acuity even with refractive correction in form of glasses or contact lens. During normal visual development, the eye and brain learns to'see' and develop binocularity, that is the ability to perceive depth (stereoacuity). This occurs in the first 8 to 10 years of life. 

Each eye transmits a clear and identical image from retina to the brain, which fuses the two images into a single image with 3 dimensions (adding depth). When the image is formed on the retina of two eyes is too dissimilar, the brain cannot fuse the two images and suppresses the more blurred image. As a result, the worse eye does not learn to'see' and becomes'lazy. This condition is seen in 1-4% of population.

The common causes for dissimilar images or amblyopia are:
1. Misalignment of the eyes or squint: it is the primary reason for amblyopia is misalignment of the eyes. In case, both your eyes are not aimed in the same direction, the image captured by each eye is different, resulting in diplopia. The brain will see from the dominant eye and suppress image from the other eye. Over a prolonged period of time, the eye dissociates from the visual cortex of the brain.

2. Refractive amblyopia:
A. Unequal refractive error in both eye. When the eye power of both eyes differ by more than 1.5d of spherical equivalent, which results in dissimilar images between the two eyes. As a result, the visual development in restricted in the worse eye.
B. High refractive error or astigmatism in both eyes, since there is a blurred image in both eyes, the normal vision development does not occur in either eyes resulting in bilateral lazy eyes.

3. Cloudiness in visual system or visual deprivation amblyopia: any kind of obstruction or cloudiness in the normal visual axis of the eye tissues can lead to amblyopia. Disorder of any kind, which blocks a clear image from being focused blocks the formation of a clear image on your retina. Commonly due to congenital or developmental cataracts or corneal opacities or prolonged closure of one eye in early childhood (drooping of one eyelid, eyelid swelling, patching of one eye).

Treatment for amblyopia
For treatment of amblyopia, a child must be compelled to utilize his affected, weaker eye. This can be done by correction of causative factor such as, treating refractive error with glasses, surgical correction of misalignment of eyes followed by patching and vision therapy, cataract surgery.

Patching or occlusion of the good eye
This is done to force the brain to pay attention to visual input from the worse eye. This allows nerve connections between affected eye and brain to develop due to, which the eye'learns to see. Eye drops such as atropine are also used for blurring the vision of the good eye. Some form of vision therapy may also be required to train both eyes to see together and develop some degree of depth perception.

To be effective, treatment should be implement as early as possible, within the period of normal visual development best within first 8 years of life. Some visual gain has been seen in selected patients up to age of 14 to 18 years. This also highlights the importance of a comprehensive eye examination as a routine in young children.

5 myths about eye health and the real facts behind them

Your eyes are an important part of your health. There are many things you can do to keep them healthy and make sure you are seeing your best. However, there are a number of myths regarding what you should do and what you shouldn't do when it comes to maintaining good eye health.

Here are 5 of those myths busted:

Myth #1: reading in dim light and sitting too close to the tv hurts your eyes

Fact: sitting too close to the tv, you may feel eye strain or get a headache from reading in the dark, but it will not weaken your eyes. It fatigues your eyes but does not harm your eye health in any way.

Myth #2: eating carrots will improve your vision

Fact: carrots are rich in vitamin a, a nutrient essential for good vision. But eating carrots will only provide a small amount of vitamin a. To get the optimum amount, you need to include other sources of vitamin a in your diet as well, some of which are milk, cheese, egg yolk and liver. Spinach is best for eye health. It has lutein and zeaxanthin, both of which can help prevent cataracts.

Myth #3: if you wear glasses or contacts for a continuous period, your eyes will weaken

Fact: your eyes will not grow weaker by using corrective lenses. The prescription may change over time due to aging or absence of disease but it has nothing to do with your current prescription. Some children have correctable eye problems that do require glasses to improve the condition.

Myth #4: when you get something in your eye, rub it out

Fact: this is not true for everything that gets in your eyes. If any particle falls in your eyes dust it off. But if it is sand and small debris that gets in your eye, don't touch it. Use an eye wash for flushing it out. If an object gets stuck in your eye, don't remove it or rub your eye constantly. Visit a doctor at the earliest because some serious injuries may seem minor at first.

Myth #5: dark sunglasses can protect your eyes from the sun

Fact: the color of sunglass does not ensure eye protection. Look for sunglasses that block both uva and UVB rays. Exposure to the UV-rays of sunlight can have cumulative effects on your eyes. It increases your risk for cataracts, solar retinitis, and age-related vision loss. Even if your contacts have UV protection, wear sunglasses that block 100% of uva and UVB rays for full protection.

Tips for Improved Eye Health

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

It's the month of Phagun again and time to prepare for the most colourful and vibrant festival of India - Holi. As the festive cheer spreads and people get ready to paint the town red with colours, dance to rocking beats at Holi bashes, and gorge on Gujiya and Thandaai, it s good to remember that you need to play it safely and naturally.

Apart from the allergies to the skin, there is also the risk of increased blood pressure after the Holi festivities due to the high intake of bhaang, the official Holi drink. To avoid the harmful effects of such materials used during the festival, here are some must-follow health tips for you.

Tips to care for your skin

Use organic colours: Skin is the most sensitive body part and synthetic colours are a big no-no for it, as they can lead to rashes and other skin allergies.

Organic colours are safe for children too, as they are softer on the skin and easy to wash off. It is crucial that you protect kids from synthetic colours as they contain lead oxide, mercury sulphide and aluminium bromide, chemicals which not only damage the skin but can also cause various health issues.
Skin and sun protection: To avoid any kind of damage to the skin from colours, apply a good amount of Vaseline, any other petroleum jelly or mustard oil to your skin. You can also apply this to your child s skin as it is completely safe for their sensitive skin. When playing outdoors, opt for a waterproof sunscreen to protect your skin against sun damage.

Tips to care for your hair

Oil your hair: You can apply a generous amount of oil to your hair, this will not only moisturize your hair but also safeguard the scalp and hair from the chemicals in the colours.
Cover your hair: Tie a ponytail and cover your hair with a shower cap to prevent your hair from dreadful damage. For a trendy look, you can also tie a bandana over your hair and safeguard them at the same time. 
Tips to care for your eyes

Wear sunglasses: Synthetic or organic, colours can be harsh on your eyes. You can protect your eyes by wearing sunglasses as they will help in preventing your eyes against any sort of damage. If your eyes come in contact with the colour, rinse them immediately to avoid infections. 
Moisturize around the eyes: Applying a good cream around your eyes will shield them from getting the colour into your eyes.
Avoid wearing contact lenses: You should refrain from wearing contact lenses while playing Holi. In case you cannot do without them, wear the eyeglasses. 
Use rose water: Rose water is known for its antiseptic and antibacterial properties and can do a great job in removing colour from the eyes. It can also be used to reduce irritation cause by the chemicals present in the colours.
Other health tips

Stay hydrated: Drink plenty of water before, during and after the festivities. Staying hydrated will not only keep you energetic but will also prevent your skin against the absorption of harmful chemicals. Drinking fluids will also ensure that all the toxins are flushed out of the body. 
Check your sweets for purity: Adulteration is at all-time high during the festive season. Therefore, make sure you buy your sweets from a reputed brand. In case, you are preparing your own sweets, buy your ingredients from a reputed shop, especially in case of products like khoya or if you can you even make that at home.
Keep your hands clean: Keeping your hands clean during the festivities can be a daunting task but since the colours used during Holi come as a fine powder and can easily get mixed with food, they can lead to different health problems. Make arrangements for snacks and drinks away from the festivity area. Make sure you wash your hands every time you touch the food.
Preventing asthma attacks: If you are an asthmatic patient, you must avoid playing with dry colours as they can aggravate breathing problems. The particles can enter your lungs and trigger an asthma attack. Asthmatic patients are also advised to carry inhalers, in order to avoid complications.
Apart from the above mentioned problems, these synthetic colors can also cause health problems like nausea, headache and vomiting in many people. Follow these tips and enjoy the festival to the fullest, while steering clear of all the harmful effects. So, forget all your worries and storm in the riot of colours. Be safe and be healthy! Have a great Holi!
