Read the following passage carefully.

1.A cataract is a cloudy area in the lens or lens capsule of the eye which blocks or distorts light entering the eye. Cataract mostly occurs in both eyes, but sometimes, it is restricted to a single eye too. During the time cataracts are forming, frequent changes in eyeglass prescriptions can be advised to better one’s vision.

2.The most common form of cataract is the senile cataract. This is a malady of old age, probably due to changes in the chemical state of lens proteins. Traumatic cataracts develop when a foreign body enters the lens capsule with enough force to cause specific damage. Complicated cataracts occur if one has suffered ailments like diabetes mellitus and hypothyroidism or other eye disorders like detached retinas, glaucoma and retinitis pigments. Infra-red rays can also cause this type of cataract. And toxic cataracts can result from medicine or chemical toxicity. Smokers have an increased risk for developing cataracts. Sometimes, a baby can be born with a cataract on one or both eyes if its mother had German measles (rubella) during her pregnancy.

3.One can prevent the onset of cataract by limiting exposure to X-rays, microwaves and infra-red radiation, using sunglasses to block ultraviolet (UV) light, avoiding overexposure to sunlight, by avoiding smoking and heavy drinking. Eat a lot of foods high in beta-carotene and Vitamin C, which are believed to help prevent or delay cataracts.

4.If the vision loss caused by a cataract is only slight, surgery may not be needed. A change in your glasses, stronger bifocals or the use of magnifying lenses and taking precautionary measures to reduce glare may help improve your vision.

5.Modern cataract surgery is safe and effective. Surgery, more often than not, can be done on an outpatient basis or may involve no more than an overnight hospital stay. A person who undergoes cataract surgery usually gets an artificial lens at the same time. This is a plastic disc called an intraocular lens placed in the lens capsule inside the eye. Other choices are contact lenses and cataract glasses. It takes a couple of months for an eye to heal after cataract surgery. Experts say it is best to wait until your first eye heals before you have surgery on the second eye if it, too, has a cataract. 

Answer the following questions briefly. 

1.How does cataract affect a person’s vision?

2.How can vision be improved when cataracts are in the process of being formed?

3.What is the chief cause of cataract in the aged?

4.What type of cataract can infra-red cause?

8.Why it not advisable to get the cataract surgery done for both the eyes simultaneously?
