CATARACT (VISION LOST AND WHAT TO DO )

First before I proceed I believe we all know how delicate the eyes his to human body that's why  I will like to share with you what what cataract is and the causes  okay let's roll on 

WHAT IS CATARACT?

   Cataract are changes is clarity of the natural lens inside the eye that gradually degrade visual quality. The natural lens sit behind the colored part of the eye (iris) in the area of the pupil and cannot be directly seen with the naked eye unless it's become extremely cloudy.the lens plays a crucial role focusing on impeded light on the retina at the back of the eye.the retina transform light to a neurologic signal that the brain interprete as vision.

CAUSES OF CATARACT

The lens is made mostly of water and protein.specific protein within the lens are responsible for maintaining it's clarity. 

Rarely cataract can present at birth or in early childhood as a result of hereditary enzymes defects, and severe trauma to the eye, eye surgery,or intraocular inflammation can also cause cataract to occur earlier in life.

 Other factors that causes the development of  cataract at an earlier age include excessive ultra-violet light exposure, diabetes, smoking,or the use certain medications,such as orals topical or inhaled steroids. 

SYMPTOMS OF CATARACT

 Having cataract is often compared to looking through a foggy windshield of a car or through the dirty lens of a camera. Cataract may cause variety of complaint and visual changes including:blurred vision, difficulty with glare (often with bright son or automobile headlights while driving at night ),dulled color vision, increased near sightedness accompanied by different changes in eye glass prescription.and occasionally double vision in one eye.

       Some people notice a phenomenon called "second sight" in which one reading vision improves as a result of their increased near sightedness from the swelling of the cataract .a change in glasses may help initially once vision begin to change from cataract; however as cataract continue to progress and opacify , vision become cloudy and stronger glasses or contacts lens will no longer improve sight 

    Cataract are usually gradual and usually not painful or associated with any eye redness or other symptoms unless they become extremely advanced.rapid and/or painful changes in vision are suspicious for other eye diseases and should be evaluated by an eye Care professionals.

WHEN TO SEEK MEDICAL CARE FOR

 CATARACT

        SINCE cataract development rarely causes any long term damage to the eye, cataract surgery should be considered only when visual symptoms begin to develop.whenever significant vision are noted you should schedule an exam by an eye care professionals . Typical symptoms may include:blurry vision, difficulty with glare or night vision,poor color vision or frequent changes in eye glass prescription.

For an early cataract changes, vision may be improved by simply changing your eye glass prescription, using a magnifying lens, or increasing lighting when you do visually demanding tasks.
