“Lutein” that protects the eyes
If lutein reduces… There is a report concluding that if “lutein,” which is the important pigment existing in the eyes, reduces or get damaged by ultraviolet rays etc., various diseases will be induced.
Lutein cannot be produced inside the body.
Much lutein is contained in green and yellow vegetables, spinaches, broccolis, etc., but it cannot be produced inside the body except by ingestions from meals.
Factors that decrease lutein
If continuously exposed to HEV* (400 to 420nm) light harmful to eyes, the eyes will be subjected to oxidative stress or lutein (pigment) deterioration will result.
Keep the eyes healthy
LUTINA material that protects lutein to protect the eyes
There is a report concluding that if “lutein,” which is the important pigment existing in the eyes, reduces or get damaged by ultraviolet rays etc., various diseases will be induced.
HEV※is blocked
Oxidative stress is reduced, and the degradation of lutein is suppressed.
There is a report concluding that if “lutein,” which is the important pigment existing in the eyes, reduces or get damaged by ultraviolet rays etc., various diseases will be induced.
※HEV…High Energy Violet light : 400〜420nm
（HEV does not represent the entire wavelength range of blue light.）
LUTINA material additionally provided with a photochromic function
The transmittances of Surf Blue, Gray, and Brown are approximately 92 to 53%, approximately 90 to 15%,
and approximately 90 to 23%, respectively, and the colors quickly change.
※LUTINA PHOTO SURF BLUE compatible only with 1.60 materials.
※The photos and illustrations are images.
※The density of the color of the photochromic lenses depends on the intensity of ultraviolet rays and temperature.
※The colors of the lenses are different from the actual colors because of printing.
※The comments are personal impressions of users and do not assure the effect or efficacy.
