What are Presbyopia and Astigmatism?
Answers
Answer:
Presbyopia:
Presbyopia is a natural part of the aging process. It is due to hardening of the lens of the eye causing the eye to focus light behind rather than on the retina when looking at close objects. It is a type of refractive error along with nearsightedness, farsightedness, and astigmatism.
Astigmatism:
A common imperfection in the eye's curvature.
With astigmatism, the front surface of the eye or the lens inside the eye is curved differently in one direction than the other.
Very common:
More than 10 million cases per year (India)
- Treatable by a medical professional
- Requires a medical diagnosis
- Lab tests or imaging not required
- Chronic: can last for years or be lifelong
