Single Vision Lenses
Single Vision Lenses offer correction for one field of vision. They have the same focal power throughout the entire lens and can be used to correct farsightedness, nearsightedness, astigmatism, or a combination. This could be for distance, intermediate (computer), or near (reading) vision.
Single Vision lenses are available in a number of materials, including regular Plastic CR39, Polycarbonate, Trivex, High Index, Transitions, Polarized and other options. Click HERE to read more about other types of prescriptions (for example, bifocals and progressive lenses).
