After obtaining optometry data at the hospital, you can choose lenses based on your own data. At the same degree, the higher the refractive index, the thinner the lens, but the more expensive it is.

The cheapest eyeglasses online provide optometry data to customer service for optometry. The following data are required: 1. left and right eye diopter, 2. pupil distance, 3. left and right eye astigmatism, 4. left and right eye astigmatism axis. Then, once the frame is confirmed, production can begin and the final package will be delivered to the customer.

In modern society, glasses are no longer just a visual correction tool, they have also become a way of fashion statement and personality expression.

However, for many people, purchasing glasses remains a challenging task. Traditional eyeglass shopping requires a lot of time and effort, but fortunately, there is now a more convenient way to wear eyeglasses online.

The vast majority of people know that online glasses matching is very cheap, but the biggest problem that makes people hesitant or skeptical is actually optometry.

As long as the refractive index is accurate, then the glasses produced will definitely be fine. In online glasses reviews, it is often said that people who are uncomfortable wearing glasses do not have all the necessary data, such as pupil distance and height, which are crucial. So optometry is really important.
