DSOM Post: Scratched Glasses Give Perfect Vision for Any Eyesight

DITCH Those Bifocals

You might soon be wearing spectacles whose lenses allow you to see clearly regardless of how long or short-sighted you are.

With age, the lenses in our eyes often lose the ability to change shape enough to focus light from near objects onto the retina - a condition called presbyopia. This leaves people who were already short-sighted unable to focus on either near or distant objects. Bifocals offer a solution by having two lenses in the same frame, but users must get used to tilting their head up or down to switch focus.
