How to prevent cataract - simple tips

     No comments


We have natural lens inside our eyes. The lens bends light rays that come into the eye and we see objects. The lens should be clear so that image of the object can focus into the eye clearer and sharper.

In the condition of cataract, natural lens inside the eye become gradually cloudy or opaque. It is like looking through a dusty or foggy car wind shield. Due to this objects look blurry, hazy or cloudy, less colorful.

Most common cause for cataract is aging. All these changes start happening in normal eye around at the age of 40. In this process lens protein start breaking down and lens become cloudy. But with time, cataracts will eventually interfere with your vision. Due to all these changes, a person feels to have blurry vision, shadow in vision, feels discomfort in bright light (bright sun light during the day or opposite car head light at night), finds difficulty while reading in dim light or night time, seeing bright color as dull or faded, seeing ‘halos’ around lights and frequent change of glasses.

Cataracts generally develop in both eyes, but not evenly. The cataract in one eye may be more advanced than the other, causing a difference in vision between eyes.

Early age cataract could be due to inherited genetic disorders, diabetes, eye injury, radiation treatment on your upper body, spending more time in sun (without UV protected sun glasses), past eye surgery, inflammation in the eye, long term of certain medication usage such as corticosteroids, smoking and alcohol consumption.
           
Treatment for cataract is cataract surgery with intraocular lens (IOL) implantation.

There are two types of intraocular lens are: Monofocal and Multifocal.

In monofocal IOL, person can see distance objects clearly and needs reading glasses. There is no difficulty at night while driving, will get sharper and crisper vision with glasses.

In multifocal IOL, person can see distance and near without glasses. But there would be difficulty at night driving, may not get sharper and crisper quality of vision.
