PS: I love how the most vicious illiterate thugs suddenly start wearing eyeglasses when hauled into court. The judge should demand copies of both of these animals' prescriptions.
If you had a good photograph of someone wearing glasses, then you can roughly tell how strong the prescription is by looking at the distortion of the face where it is covered by the lens. If there's no distortion, then either you have a very weak prescription or the glasses are just there to make you look smarter.
