[Magdalen] Specs advice?

[Grace Cangialosi]

I certainly wasn’t meaning to dis optometrists! It was an optometrist who caught my first detached retina. And he also did a field of vision test. I guess my bias is that periodically it’s a good idea to look at the medical side of eye care.
At this point I’m dealing exclusively with an ophthalmologist, having some level of glaucoma in my left eye.
Another advantage, of course, is that insurance will cover them, if it’s diagnostic or anything other than a routine check-up.
