Eyeglasses matching is different from offline glasses matching, mainly because offline glasses matching allows you to effectively perform optometry and select frames. Large chains best place to buy eyeglasses generally provide very thoughtful services, so it is also the biggest reason why most people choose online glasses matching nowadays.

Optometry is mainly used to measure the degree of myopia in one's own eyes. The most direct and well-known factors, such as the degree of discount prescription glasses and astigmatism, are often determined through computer optometry.
For example, in a computer optometry sheet, S, C, and A respectively refer to the degree of the S-ball lens, which is the degree of the glasses, the degree of the C-axis lens, which is the degree of astigmatism, and the A-axis position, which is the direction of astigmatism. But this alone is not enough for optometry, because there is a difference between the computer optometry degree and the final fitting degree.
