Question

Which of the following disorder of the eyes caused by UV radiation?
A. Cataract
B. Glaucoma
C. Dilation pupil
D. Some defects of the retina

Answer 1

Hint:
An eye problem can hit at any time. A few eye problems come with age while others may be serious disorders. The four most prevalent eye conditions that lead to blindness or vision loss are Diabetes-related retinopathy, Cataracts, Glaucoma, and Age-related macular degeneration.

Complete answer:
Exposure to intense ambient radiation can pose a hazard especially if the recipient is over 40 years of age. This exposure to radiation can result in impaired vision and permanent or transient blindness. Both ultraviolet-A (UV-A) and UV-B produce cataract formation and are not essential in sight. Ultraviolet radiation is also a risk factor for harm to the retinas of children.
Glaucoma is a group of eye diseases that harm the optic nerve, the health of which is essential for good vision. This damage is frequently caused by abnormally high pressure in the eye. Glaucoma is one of the main causes of blindness for humans above the age of 60.
Pupil dilation is carried out to purposefully raise the size of the pupils during an eye exam so that ophthalmologists can fully study the health of the retina and optic nerve. The exam is essential to prevent and treat eye conditions that could potentially result in vision loss.
Retinal diseases are disorders that affect light-sensitive tissue on the back side of the eye. Diseases may consist of retinal detachment and diabetic retinopathy. Once the retina retracts from the blood vessels that supply oxygen, it leads to a medical emergency referred to as a retinal detachment.

Option ‘A’ is correct

Note:
A cataract is a cloudy lens. The lens is located behind the coloured part of your eye (iris). The lens focuses light that passes into the eye, which produces clear, sharp images on the retina — the light-sensitive membrane in the eye that works like the film in a camera.
