What Are Varifocal GlassesVarifocal glasses (or progressive glasses) are primarily used to ease presbyopia and other accommodation issues. They have no visible lines and can correct farsightedness, intermediate vision, and nearsightedness. To ensure optimal use, select the appropriate frame, and the lens height should be at least 28 mm to meet various prescription needs. |
How Varifocal Glasses WorkBecause varifocal glasses have different prescriptions in different areas, they need to be adjusted to meet individual needs when in use. The top of the lens is the farsighted area, which is suitable for viewing distant objects, such as watching TV or enjoying the scenery; the middle is for intermediate vision, such as using a computer or cooking; and the bottom is the near-sighted area, which is ideal for close work, such as reading, sewing, or painting. |
Adapting to Varifocal LensesVarifocal lenses have three invisible zones, allowing smooth transitions between near, intermediate, and distant vision. These lenses use advanced optical technology, providing excellent wearer satisfaction when tailored to individual needs. However, some users may need time to adapt, as the eye and brain must adjust to the varying refractive powers. For example, when climbing stairs, the wearer looks through the bottom section, designed for reading at 40 cm. The steps may appear distorted as they are further away. The good news is that the visual system quickly adapts, and when descending stairs, the wearer can simply tilt their head slightly to adjust. |
