What is single vision lenses?

Single vision lenses are a type of spectacle lens that provides a single prescription for correcting nearsightedness, farsightedness, or astigmatism. These lenses provide the same level of correction across the entire lens and are meant for individuals who need correction for only one specific distance, whether it be reading, computer work or distance vision. Single vision lenses are available in a variety of materials such as glass, plastic or polycarbonate, and can be made to fit any frame style. These lenses are also available in various index options (thickness of the lenses) based on the individual's prescription and preferences. They are typically prescribed for individuals who are under the age of 40 and have no significant issues with eye health or vision.
