Question

Presbyopia is connected by

• A. Concave lens
• B. Convex lens
• C. Bifocal lens
• D. None of the above

Answer 1

The correct option is C Bifocal lens

B. Bifocal lens.

Solution: Presbyopia is an age-related process which is a gradual thickening and loss of flexibility of the natural lens inside the eye. These age-related changes occur within the proteins in the lens, making the lens harder and less elastic over time. For centuries presbyopia was corrected with the use of bifocal eyeglasses.

Hence option B is correct
