Question

Tara’s grandmother is 70 years old and has a passion for embroidery. She faces difficulty in threading the needle as the eye of the needle appears blurred. The ophthalmologist diagnosed it as an age-related disorder.

1. Name the eye disorder she is suffering from.
2. How can the above defect be corrected?
3. Where is the image formed in the above disorder?

Answer 1

1. Tara’s grandmother is suffering from Presbyopia, which is a common eye defect in old age.
2. The defect can be corrected with a convex (converging) lens of suitable focal length, often in the form of reading glasses or bifocal lenses.
3. In this disorder, the image of nearby objects is formed behind the retina, making it difficult to see close objects clearly.
