Does irregular use of glasses worsen eyesight?

Does irregular use of glasses worsen eyesight?

Not at all: Glasses are like crutches - their job is not to heal you, only to help you with what you've got.

As long as your ophthalmologist feels that the internal eye pressure is not being increased, this is ok. ...Read more
