[0002] Lenses are the main component of glasses and are used to correct vision, protect the eyes or serve as fashion accessories. Photocuring can make the internal structure of the lens material tighter, thereby improving the hardness and wear resistance of the lens and extending the service life of the lens. At the same time, during the photocuring process, the material can be distributed more evenly, reducing defects such as pores and grain boundaries, thereby improving the transmittance and optical performance of the lens.
