I've always wanted lenses, but my eyesight is good
Do you know what your clarity of vision is, or VA?
What's VA?
VA is visual acuity. It depends on factors like the health of the retina, the sensitivity of the interpretative faculty of the brain, etc.
Oh, how would I find that out?
I would think an Optometrist. If you're having trouble with vision, a cause could be a refractive error, meaning a problem with how light is refracted in the eyeball.
Oh no i'm not having trouble with vision. I have great vision
Awesome! I am near-sighted myself. So light focuses in front of my retinas instead of on.
Oh, do you have corrective lenses?
I do. They were prescribed to me by an ophthalmologist.
