Why do most people wear spectacles as they grow old?

Answer 1

First, not everyone needs glasses as they age.

Second, the lens of the eye can become warped over time. Glasses generally don't correct the lens but warp the direction of light so that they hit the retina normally.

As people get older, the lens of the eye becomes less flexible, making it difficult to focus on things that are very close to you. It's called presbyopia, and it's why most people need reading glasses as they get older.

Answer 2

-Because their eyes are weak and canot see as well as they used to.

Answer 3

Normally, you don't. But sometimes because of puberty your vision will go haywire and it'll be better to just be prepared.

Answer 4
