Question

In the following abnormalities of the eye, which one of the following is a serious condition that leads to blindness?
A. Presbyopia
B. Myopia
C. Hypermetropia
D. Glaucoma
E. Astigmatism

Answer 1

Hint:-The inability to see anything, even sight, is blindness. Legal blindness refers to severely impaired vision. From just 20 feet away, a legally blind person can see what a person with normal vision can see from 200 feet away.

Complete solution:Presbyopia is the progressive deterioration of the capacity of the eyes to concentrate on objects nearby. It's a normal aspect of ageing that is sometimes irritating. In the early to mid-40s, presbyopia typically becomes apparent and begins to intensify until about age 65.

Myopia(Nearsightedness) is a general vision disorder in which you can easily see objects around you, but fuzzy objects further away. It happens when your eye structure allows light rays to bend (refract) wrongly, reflecting images on your retina rather than in front of your eyes.

Hypermetropia (long-sightedness) is a common eye disorder where objects nearby appear distorted, but when looking at something farther out, the vision is sharper. You may have hypermetropia if you find your eyes are always drained and you have trouble concentrating on things close to your eyes.

Glaucoma is a category of eye disorders that affect the optic nerve, the well-being of which is essential for healthy vision. This injury is also caused by pressure in the eye that is abnormally high. For adults above the age of 60, glaucoma is one of the primary causes of blindness.

Astigmatism is a form of refractive error where the eye does not uniformly concentrate light on the retina. This, at some distance, results in blurry or blurred vision. Eyestrain, headaches, and difficulty driving at night may be other symptoms.

So from these discussions we can conclude that Glaucoma is a serious eye condition which can lead to blindness. Therefore the correct answer is option (D).

Note:-
The long-term outcome of a person for restoring vision and slowing vision loss is stronger where care is promptly preventive and pursued. Have regular eye exams to diagnose eye conditions and to prevent vision loss. Treatment of medicine will help avoid blindness if you are afflicted with such eye disorders, such as glaucoma. Surgery can cure cataracts successfully. It doesn't immediately lead to blindness. In cases of glaucoma and macular degeneration, early diagnosis and treatment are also critical for helping to slow down or halt vision loss.
