Can I choose the 1.5 index lense even though I have srtong power?
I have a question about lens. While I will be getting a prescription shortly, I already know from past experience that the prescription is always high due to extreme nearsightedness. I realize that special glasses like sunglasses, polarized and bifocals are extra. But what about single vision, but high prescription lens? Can I choose the 1.5 index even if it results in thicker or bigger glasses to avoid the charge? I am on a very limited income, which is why I am considering buying glasses online. And I would like to know before I go to the eye doctor whether it's cheaper to do it through net or to just get it from them.
