What is Presbyopia?
Presbyopia is a natural part of aging where the eye's lens becomes less flexible, making it harder to focus on nearby objects.

How Convex Lenses Help with Presbyopia
As we age, the eye’s lens hardens and loses flexibility, preventing it from focusing light directly on the retina for close-up tasks like reading. Convex lenses (reading glasses) converge light rays before they enter the eye, helping focus light properly and making near objects appear clearer.
