Is it OK for you to use glasses lower than your prescription if you're shor!
Question: Is it OK for you to use glasses lower than your prescription if you're short-sighted?
So it's like a -0.75 difference. Will this make a difference?
Answers:
It won't hurt your eyes to wear glasses weaker than what you need, but you won't be able to see quite as well as you could if they matched your actual prescription.
Sure it will make a difference...you won't see as well as you should.
