The performance of good eyeglass online lenses in terms of material, design, and film layer is better. Good lenses provide a better visual experience, are less likely to get dirty, maintain clarity for a long time, are wear-resistant and easy to maintain, and offer better protection against UV and blue light.

Consumers can choose the best eyeglass online lenses within their budget, and it is not recommended to force themselves to buy lenses that they feel are too expensive. Good lenses are only raw materials and semi-finished products, and good lenses also need to be based on scientific fitting to exert their advantages.

Check and separate, in case of discomfort, no one will handle it for after-sales service. We should provide one-stop service in one place, and when there is after-sales service, we should contact them. This way, optometry data sometimes does not equal fitting data, and fitting data often needs to consider many other factors to provide more scientific prescriptions.

How can I create lightweight and thin glasses? How thick are the lenses made? Frame size. Assuming a customer's pupillary distance is 60, if the pupillary distance of the frame (i.e. the distance between the geometric centers of two pieces) is 70, divided by 2, it should be 5 millimeters to move the center point.

The amount of heart transfer is the fundamental factor that determines eyeglass online thickness. The myopia film has a thin center and thick edges. So the thicker it gets towards the edge.

Pupil distance size. Assuming that a person with a distance of 70 and 68 pupils has a heart shift of only 1, while a person with a distance of 58 pupils has a heart shift of 6. Assuming all other factors remain constant, those with a smaller natural pupillary distance will be paired with thicker ones.
