Defocused Customized Myopia Spectacle Lens

​One Person One Horizon

Designed according to the wearer's defocus data measured by the Multispectral Refraction Topography (MRT) Technology.

Compared with the single vision lens, one-year clinical report shows,
  • Control efficiency of SPHERICAL EQUIVALENT is 72%. *
  • Control efficiency of EYE AXIAL GROWTH is 64%. *



*Data source:《The effect of individualized ocular refraction customized spectacle lenses on myopia control in schoolchildren A 1-year randomised clinical trial》-West China Hospital of Sichuan University

Traditional myopia-controlling spectacle lens are designed based on standard data, but we found that the Relative Peripheral Refractive Error (RPRE)  of each eye is totally different through using MRT Technology. Can these lens really make each eye achieve a good control effect?

​















Wearing myopia spectacle lens designed based on standard data: 










         some can successfully correct for myopia defocusing          some can only correct a portion of myopia defocusing        some cannot be successfully corrected for myopia defocusing


Thondar defocused customized myopia spectacle Lens are designed and processed based on the wearer's peripheral refraction. Regardless of the defocused state of the eye, it can form a stable and effective myopia defocusing after wearing, achieving better myopia control effects!


CUSTOMIZATION PROCESS:

Except conventional refraction, apply the MRT measurement in 2​.5 seconds. The intelligent algorithm will help you get the data for customization.
