OPN5 Violet Light Illustration

Primary tabs

A diagram illustrating how violet light interacts with the photoreceptor protein OPN5 to prevent progression of myopia. At top, A, a normal eye. In the middle, B, shows a myopic eye with characteristic elongation between the cornea and the retina and a thinning of the vascular layer called the choroid. The bottom, C, shows that violet suppresses the elongation and thinning of the choroid. (Illustration: Toshihide Kurihara)
