What kind of lens do I need for astigmatism?
Toric contact lenses are often the best choice for contact lens wearers with an astigmatism, because they’re specifically designed to address the problem. The special shape of a toric lens creates different refractive, or focusing, powers that can help correct either a corneal or a lenticular astigmatism.
Are there progressive reading glasses?
No-Line Bifocal (Progressive) Reader Lenses have no power at the top of the lens and reading at the bottom. The bottom reading power is typically chosen for 12-14 inches away. Reading powers run from +1.00 to +3.00 in quarter diopter steps.
How do I know what strength reading glasses I need?
Look to see what line has the smallest print you can read without straining. For example, if you can read the +1.5, but the +1.00 is blurry, then you know you likely need a strength of +1.00. Start at the first line and move to lower lens strengths to determine the most appropriate fit.
