Should I choose various film-coated lenses? Look at the discountglasses functionality. If people have heavy wear on their lenses, they can increase the hardness and wear resistance of the lenses by applying a reinforcement film.
If you spend a long time in front of your phone's electronic screen every day, it is recommended to use anti-blue light film, which can filter out a small amount of harmful blue light generated by electronic products.
Is buying online the same as buying in a physical store? Of course, it's different. No matter where you buy it, scientific and accurate optometry is a prerequisite. Glasses require a series of accurate optometry data, and then match discountglasses with one's eye condition based on degree, pupillary distance, and pupil height.
How to choose a mirror frame? Frame glasses, of course, require frame inventory. Are there any standards for selecting frame materials? No, we mainly choose according to our own needs and budget.
For example, students with high levels of myopia may tend to choose lighter frames, while students who enjoy exercising and spending long periods outdoors can choose frames with better sun resistance. Of course, these are not fixed standards, it still depends on everyone's needs.
After selecting the material, choose the frame you like, but be sure to match the width of the frame with the distance between the pupils. Whether it matches or not will be informed by optometrists or optometrists during the fitting process. When the eyes are not moving, the optical center of the assembled discountglasses should face the center of the wearer's pupil.
Most glasses can be made by moving the optical center inward or outward to ensure that the light, optical center, and pupil center are straight. If it is not in a straight line, the prism effect will occur, causing blurred vision and eye damage.
