Myopia lenses are specially designed spectacle lenses that have a combined action of correcting blurred distance vision and slowing eye growth that causes increasing myopia in children and teenagers.
Lenses are a key component of spectacles, and only special designs of spectacle lenses help reduce or slow the progression of myopia in children and teenagers. Single-vision spectacles, whilst inexpensive and convenient, do not help slow the progression of myopia.
New spectacle lens designs are available for myopia control. These designs incorporate either 'lenslet' or 'diffusion' technology.

Myopia control spectacle lenses do two jobs at once: they provide clear distance vision and send signals that tell the eye to slow its growth.

 

They incorporate standard vision correction and build in myopia control technology.

1. Standard vision correction A basic single-vision lens is concave (thinner in the centre, thicker at the edge). It bends incoming light so it lands neatly on the retina instead of in front of it, clearing up blurred distance vision.
2. Built-in myopia control technology

 

Modern myopia lenses use smart optics that guide the eye to grow more slowly. They work in three clinically proven ways:

• Peripheral myopic defocus – keeps central vision clear while shifting peripheral light to focus just in front of the retina to provide a signal to the eye to slow down.
• Lenslet / multifocal ring designs – tiny lenslets arranged in concentric rings surround a clear central zone, creating a gentle “zone” of myopic defocus.
