Features

UV Protection

SEED UV-1 contains UV absorber that blocks ultraviolet rays by 80% or above for UVA and 90% or above for UVB.

What are ultraviolet (UV) rays

Sunlight consists of visible light and invisible light as shown in the illustration. Infrared light and ultraviolet light are different types of invisible light. Ultraviolet light has the shortest wavelength of all light that reaches the face of the Earth and can be further subdivided into three ranges, UVA, UVB, and UVC.

UV-C Absorbed by the ozone layer and does not reach the surface of the Earth.
UV-B Mostly absorbed by the ozone layer, but partly reaches the surface of the Earth.
Said to be a cause of skin cancer and certain eye disorders (photokeratitis, pterygium, etc.).
UV-A Least dangerous of all ultraviolet subdivisions, but can be a cause of skin aging (wrinkles, sagging, etc.).

Light transmission spectrum

The light transmission rates are measured using SEED UV-1 and a lens with no UV protection.

Lens design

This series adopts a proprietary lens design that is comfortable on the eye and has good tear exchange.

Lens design of SEED UV-1

As shown in the illustration, the lens bevel forms a two-step curve, which reduces contact with the cornea, relieving discomfort. Keeping the bevel afloat also provides for good tear exchange.
