Single vision lenses are eyeglass lenses that have a single prescription power throughout the entire lens surface. They are used to correct one type of vision problem, such as myopia (nearsightedness), hyperopia (farsightedness), or astigmatism.
Single vision lenses are available in various materials,
- plastic,
- polycarbonate
- high-index plastic
- glass
They can also be treated with coatings to improve their scratch resistance, anti-glare properties, and UV protection.
Single vision lenses are the most common type of lenses used in eyeglasses and are suitable for people who have only one type of vision problem. They are often prescribed for children, who typically have only one type of vision problem, and for adults who require glasses for reading, driving, or other specific tasks.
If you have multiple vision problems, such as presbyopia (age-related near vision loss) and myopia or hyperopia, you may need bifocal or progressive lenses, which have two or more prescription powers blended together on a single lens surface.
