Zinff lightweight single vision clear lenses correct one field of vision, either distance vision or near vision. We can fill prescriptions between -18.00 and +10.00 sphere. Or up to +/- 4.50 cylinder using the high-quality CR-39, MR-8, MR-7, and high-index aspheric lenses.
Zinff high-index aspheric lenses are recommended for people with strong prescriptions. These lenses are an ultra-thin, lightweight alternative to 1.50 standard lenses, which get thicker (and heavier) as your prescription gets stronger. We have multiple high-index options for different strength of eyeglasses prescriptions.
