This will probably be my next pair of rx eyeglasses that I will order. My current rx is -5.50 diopters for my left eye and -4.50 diopters for the right eye. These will be -20 diopters for both eyes with mid index lenses. I will wait until I get a 20 dollar or so gift card to order them. I am very exited to eventually order them and wear them while swinging, ziplining or thrift shopping with the girl Crissie that I go out with often.

They will have lenses sort of like these.
Except without bifocals.
