Description

Technical Field

[0001] The utility model relates to the technical field of photochromic glasses, in particular to a photochromic lens and glasses. Background Art

[0002] At present, color-changing glasses are mainly divided into three types: metal ion redox type, liquid crystal light valve type and guest-host liquid crystal type, among which the first two types are more common. In the prior art, color-changing glasses using liquid crystals, such as liquid crystal light valve type and guest-host liquid crystal type, include a liquid crystal box, and a glass substrate is used when generating the liquid crystal box.

[0003] According to the principle of reversible photochromic reaction, the lens can darken quickly under the irradiation of light and ultraviolet light, blocking strong light and absorbing ultraviolet light, and showing neutral absorption of visible light; when returning to the dark, the lens can quickly return to the colorless and transparent state to ensure the light transmittance of the lens. However, the contact volume of the color-changing substance in the photochromic coating with sunlight is limited by the volume of the photochromic coating, so the dimming performance of the photochromic lenses is poor.
