The frame size has increased.
The larger the frame is, the more obvious it is now, so the edge glare will be more obvious when the lens is polished. It interferes with the visual effect. The frame height of the new glasses must be much larger than the height of the old glasses. Because when you buy big frame glasses, they must find out the pupil height when matching outfits. When you get glasses fitted at the opticians, the opticians don't measure the pupil height. That is, the balance line of the lens should be properly moved up when the lens is processed. If it is not moved up, it cannot be seen clearly.
Wearing glasses correctly will not get deeper degrees
The development of myopia is not directly related to wearing glasses. Patients with myopia wear suitable glasses and pay attention to eye hygiene, and the degree of myopia will stabilize at a certain level. But if you think that with glasses, everything will be fine. If you don't pay attention to eye hygiene in normal times, if you continue to keep your eyes in a state of fatigue for a long time, it will lead to vision loss and deepening of myopia. In addition, wearing improper glasses such as no optometry or inaccurate optometry, too large power, will increase the burden on the eyes, reduce vision and deepen the power. For some people with high myopia (more than 600 degrees), although they insist on wearing glasses, the degree will still deepen, accompanied by changes in the fundus, which is medically called pathological myopia. This deepening of myopia is related to the degree of myopia and family and has nothing to do with wearing glasses.
What color coating is good?
The purpose of plating anti-reflection film is to reduce the reflection of light. But because it is impossible to be completely free of reflected light, there will always be some residual reflection on the surface of the lens that causes the visible color. Someone asks which kind of these residual color is best. It does not have a standard actually. It is mainly based on a personal preference for color. More on the market at present is green color. However, these residual colors can initially help us to judge the thickness of the film: when the film is thin (the thickness is less than 139nm), the reflected light will show light yellow, and when the film is thick (the thickness is more than 139nm), it will show blue-green. The current multi-layer anti-reflection film thickness is about 0.3μm.
Can blue glasses double up as sunglasses?
The main function of sunglasses is to keep out dazzling strong light, to reduce the eye adjustment that causes fatigue or the harm that strong light stimulation causes. Their light transmittance is very low, only suitable for use when the sun is strong outdoors. If wearing sunglasses indoors, or at dusk, or even in the evening, because the light is reduced, it will not play a role in protecting the eyes or even will increase the burden of the eyes. The Anti-blue lens is yellow-green and needs to meet the transmittance and blue obscurity. If you are walking outdoors for a short time, good blue light glasses can of course completely meet your outdoor eye protection needs, but due to the high light transmittance, it is not suitable for a long time outdoors, as the sunglasses. Because although it can block UV rays, they are not very good at the filtering of strong light. General anti-blue glasses can not be equal to sunglasses, the main function is not the same, and the use of the scene is not the same.
Can you buy prescription glasses for night driving?
Your eye doctor may prescribe special night driving glasses with an anti-reflective coating. AR coating helps reduce glare, improves vision, and helps you see better on the road at night. The lenses developed using wavefront diagnostics reduce halos, stellar bursts, glare, and other visual disturbances.

Blue light in electronic products
In addition to the blue light that exists in natural light, LED energy-saving lamps, fluorescent lamps, computer monitors, mobile phones, and other digital products will emit blue light because of the use of light-emitting diode LED technology. Some people think that blue light hurts the eyes because blue light is not absorbed by the cornea and lens like ultraviolet light. The blue light can pass through the refractive medium of the eye to reach the retina, and then be absorbed by the pigment epithelium of the retina, which will cause aging and functional degradation of the retina over time.
The eyes also have many protection mechanisms, such as squinting, pupil contraction, lutein contained in the macula of the retina, and the retina's own antioxidant repair mechanism, which protect our eyes from blue light damage. And after scientific testing, it is found that the blue light emitted by electronic products is only several hundredths of the intensity of blue light in natural light. This means that as long as the electronic products are not used continuously every day (for example, more than 8-10 hours a day), the blue light will not cause obvious damage to the eyes.
