Overview

A myopia lens, also known as a concave lens or minus lens, is specially designed to correct myopia, commonly referred to as nearsightedness. People with myopia can see nearby objects clearly, but distant objects appear blurry. This occurs because light entering the eye focuses in front of the retina rather than directly on it, typically due to an elongated eyeball or an overly curved cornea. Myopia lenses are thinner at the center and thicker at the edges. They work by diverging incoming light rays so that they are focused precisely on the retina, allowing for clear distance vision. The strength of these lenses is measured in diopters (D) and is represented with a negative sign (e.g., -2.00 D). Myopia lenses can be fitted into a variety of frames and are available in different materials such as plastic, polycarbonate, and high-index materials, offering options for lightweight, durable, and aesthetically pleasing glasses. They are a common, effective, and non-invasive solution for managing nearsightedness.

How Its Works?

Myopia lenses work by correcting the way light enters the eye in people with nearsightedness. In a myopic eye, light rays focus in front of the retina instead of directly on it, making distant objects appear blurry. Myopia lenses, which are concave in shape, help by diverging the incoming light rays slightly before they reach the eye. This adjustment shifts the focal point backward so that the light focuses directly on the retina. As a result, distant objects appear clear. These lenses are typically used in eyeglasses or contact lenses and are prescribed based on the level of correction needed, measured in negative diopters.
