Abstract

The invention provides a lens capable of improving night vision and preventing glare, and a preparation method thereof. The lens comprises a substrate sheet, and a first protective film layer and a second protective film layer which are arranged on a front side and a rear side of the substrate sheet respectively, wherein the first protective film layer is used for preventing glare and improving the light transmission capacity, and the second protective film layer is used for improving the light transmission capability. The lens is advantaged in that the first protective film layer and the second protective film layer are arranged on a surface of the substrate sheet, the light transmission capacity is improved, brightness of the night environment is enhanced, the glare is prevented throughthe first protective film layer, and the night visual observation capacity is improved.

Description

technical field [0001] The invention relates to the technical field of optical lenses, in particular to a lens for improving night vision and anti-glare and a preparation method thereof. Background technique [0002] With the development of the economy, people pursue a better quality of life, and the requirements for glasses are becoming more and more stringent. [0003] Glare is an undesirable lighting phenomenon. When the brightness of the light source is extremely high or the brightness difference between the background and the center of the field of view is large, glare will occur. For example, when a driver is driving at night, his eyes are suddenly irradiated by the opposite car with high beams on, which is a kind of glare pollution. Waking up at night and suddenly being illuminated by lights in the eyes is also a kind of glare pollution. Light glare can cause discomfort to the eyes, and severe glare can damage vision. Especially long-term exposure to glare pollution...
