Personalizing of spectacles.

Spectacles are vital for correcting vision. Individuals who need vision correction can choose to wear spectacles or contact lenses. Alternatively, they may choose to have a vision-correcting operation. Therefore, researchers focus on vision science and spectacle design. Although some studies have compared spectacles and contact lenses for better visual quality, there is no consensus regarding which are better for the correction of vision. With the development of technology and the improvement of living standards, the design and production of spectacles will focus on personalized style, lenses, and frames. In this paper, we introduced trends in spectacles and studies of the relationship between frame sizes and face sizes, attempting to provide a feasible program for the personalization of spectacles-the Personalized Spectacles Program. Furthermore, certain limitations, such as non-personalized and misused spectacles, which have elevated the importance of the design and production of personalized spectacles were discussed.
