Myopia Control Methods

Defocusing Spectacles\

(e.g.: HOYA MyoSmart Defocus Incorporated Multiple Segments (DIMS) Spectacle Lens/Carl Zeiss Myovision)

One of the main reasons for myopia progression is the presence of an abnormal ‘defocusing signal’ at the peripheral retina. In conventional myopia spectacle lens, although the central vision is corrected, allowing the eye to see clearly, this abnormal signal at the periphery is still present, which continues to cause the eyeball to grow.

In these special-designed spectacle lens, while the central part corrects the myopia (just like conventional lens), a ‘peripheral myopic defocusing effect’ is created at the peripheral zone. This peripheral defocusing effect can reduce the stimulus that causes eyeball to grow, therefore achieving better myopia control.

Progressive glasses

(e.g.: Carl Zeiss MyoKids)

In progressive glasses, the upper part of the lens is designed for seeing far objects, while the lower part is for near objects. Although its myopia control effect is not as significant as either atropine or the other defocusing spectacles, it is particularly useful in children who are also on higher concentration (0.125% or 1%) atropine treatment, because it can counter-correct the blurred near vision associated with the use of higher-concentration atropine.
