If you would like to replace the lenses on your existing frame, please send us the frame.
We will make it with the same frequency. If you wish to change the lens power, please let us know the lens power.
Ray Guard 435 blocks almost 100% of ultraviolet rays, which are said to be harmful to the eyes. Furthermore, by reducing visible short wavelength light (blue light), it reduces glare and flickering, and reduces contrast loss.
Spectral transmittance curve comparison Visible light short wavelength light (blue light) 380nm to 500nm Comparison of conventional lens (1.60 material, SFT coat) and RayGuard435 (1.60 material) in wavelength range. Approximately 20% reduction compared to the naked eye near 435nm to 440nm. *The spectral transmittance curve is displayed in sweet (pink). *The spectral transmittance of each color is almost the same as Sweet.
