Title:
SPECTACLE LENS FOR SUPPRESSING PROGRESSION OF REFRACTIVE ERROR
Document Type and Number:
WIPO Patent Application WO/2024/038731
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide a spectacle lens for suppressing the progression of refractive error, the spectacle lens having both high capability of suppressing the progression of refractive error and predetermined refractive power for normal refraction correction. This spectacle lens has, around an optical center region 22 to which predetermined refractive power for refraction correction is added, an optical region 23 having refractive power different from the refractive power of the optical center region 22. The optical region 23 is continuously disposed in a net shape around a large number of island-shaped regions 24 having the same refractive power as the refractive power of the optical center region 22 and disposed to be separated from each other.
