Resin glasses are colorful, and the price of the material is beneficial. Because the child is in the development period, glasses are changed more frequently. Therefore, summarizing the above factors, the resin frame is the most suitable for children to wear. A high degree of myopia must choose a small frame. If the child's myopia or farsightedness is high, the lens will be very thick, so be sure to choose a small frame. Because the frame type is small, coupled with the lightweight of the resin frame, it has better fixing performance than other materials.
Understand blue light correctly.
Blue light has been shown to affect the body's circadian rhythms, with too much exposure to it late at night from gadgets such as mobile phones disrupting a person's ability to fall asleep.

What kind of glasses are bifocals?
Bifocals are mainly used in presbyopia correction, providing presbyopic opticians with a clear vision for both near and far use in one pair of glasses. The bifocal lens can be divided into two separate areas, with the upper part of the lens providing clear distance vision and the lower part providing clear near vision.
