The reasonable choice for high myopia is a small frame and high refractive index discount prescription glasses lenses. Myopia lenses are concave lenses, thin in the middle and thick at the edges. As long as the lens is above 500 degrees, it will not be thin.

If you choose a large frame for high myopia, even if you choose 1.74 lenses, they are still thick and heavy, easy to slide down, press your nose, and have a poor wearing experience.

When looking at electronic screens, wearing blue light lenses is better than not wearing them, as it blocks some harmful blue light and can protect the eyes. However, when looking at a distance, the background color can affect clarity, resulting in insufficient clarity and causing eye fatigue, which can deepen myopia.

A reasonable choice is for people who see far away to not need blue light discount prescription glasses lenses, and it is best to have blue light effects when looking at the screen. Different functions of glasses are suitable for different scenarios.

The plate lens frame is selected for the multifocal lens, so it is impossible to adjust the nose support, the pupillary height position, and the distance between the lens and the eye. Moreover, the distance between the lens and the eye is relatively small, making it difficult to see the lower part of the lens.

A reasonable choice is a metal discount prescription glasses frame with an S-shaped nose support. The optical center point should not move too much, the pupil height should be as high as possible above the midline, and the position of the post head should avoid adjustable thick post heads, double post heads, etc.

Different ages, different optometry prescriptions, different lifestyles, and different professions should have different choices. A reasonable choice is to provide different solutions based on different situations.
