Definitions
- the present invention has the ability to selectively block or reduce only light of a specific wavelength, and to block ultraviolet rays that are harmful to the human eye.
- the present invention relates to a transparent plastic material having a performance of selectively blocking or reducing, and an optical article made of the material, which is easy to manufacture and lighter in weight than the conventional one, and has excellent temporal stability. Material.
- Conventional technology
- the human eye is near 5.55 nm in photopic vision (photopic)
- Sunglasses are generally used to prevent this glare.
- sunglasses have only a color on the lens, which reduces visibility.
- those that do not absorb UV light adequately (do not block UV light) result in dimmed sight and dilated pupils, increasing the amount of UV light that enters the eye.
- This ultraviolet light is harmful to the eyes, and it is said that the wavelength of 280 to 315 nm (UV-B) is absorbed by the cornea and causes damage to the cornea such as keratitis.
- UV-B the wavelength of 280 to 315 nm
