When looking at an electronic screen, wearing blue light discountglasses lenses is better than not wearing them, as they block some harmful blue light and can protect the eyes. However, when looking far, the presence of background color can affect clarity, resulting in insufficient clarity and causing eye fatigue, deepening the degree of myopia.

A reasonable choice is that people who see far away do not need blue light lenses, and it is best to have a blue light effect when looking at the screen. Different eyeglass online functions are suitable for different scenarios.

The plate lens eyeglasses online cheap frame is an obvious layman's choice for the multifocal lens. Because the plate lens frame is generally an integrated nose support, it is impossible to adjust the nose support after matching, the pupil height position and the lens distance cannot be adjusted. Moreover, the distance between the lenses is too small, which may make it difficult to see the lower part of the lens, resulting in difficulty in getting close. Mirror matching failed.

A reasonable choice is a metal frame with an S-shaped nose rest, with the optical center point moving as little as possible. The pupil height should be positioned above the centerline as much as possible, and the position of the pile head should avoid adjustable thick pile heads, double-pile heads, etc.

Different ages, different optometry prescriptions, different living conditions, and different professions should have different choices. Provide different solutions based on different situations. For example, if one is older, and has complex prescriptions, and needs such as exercise and buying a car, then choosing a comfortable model cannot meet these needs.
