Description

Contact lenses and contact lens products

The present invention relates to a contact lens and a contact lens product, in particular to a contact lens and a contact lens product containing a photoluminescent substance that can react quickly.

Conventional contact lenses generally use traditional photochromic compounds for the purpose of light reduction and shading. Because traditional photochromic compounds do not respond well to light, the color change takes more than a few seconds. When entering a room with low light, the contact lens still maintains a dark color and excessively reduces the light. The insufficient amount of light will cause poor vision, which may affect safety.

According to the present invention, there is provided a contact lens comprising at least one color changing area, wherein the color changing area includes at least one photoluminescent substance, and the photoluminescent substance is curcumin or a curcumin derivative. The average transmittance of the discoloration zone at a wavelength of 400nm~700nm is T4070, the total area of the discoloration zone is AC, and the total area of the contact lens is AL, which meets the following conditions:

According to the present invention, another contact lens product is provided, which includes the contact lens described in the preceding paragraph and a light-proof package, wherein the aforementioned contact lens product is a daily disposable type.

When T4070 and AC/AL meet the above conditions, the photoluminescent material in the discoloration zone of the contact lens of the present invention can quickly achieve the discoloration reaction within 1 second after absorbing light of the appropriate wavelength, such as changing from yellow to green , So it can immediately react to and change the light, helping to quickly respond to changes in the intensity of the ambient light. Furthermore, if the contact lens of the present invention is designed with a photoluminescent material to cover the optical zone, it can effectively convert strong energy UV light into weaker energy light, so as to protect the retina and reduce damage.
