Choose the right lenses for blue light glasses.
Since visible light is made up of yellow, green, and blue light, the blue lens blocks the blue light, leaving only yellow and green light. Yellow plus green is yellow, so what we see is a yellow lens. If it is viewed from the side, we will find that the lens is also transparent, with no background color, and most of it is yellow-green. The dark yellow blue lens appears chromatic aberration, and it can be more serious. So to block blue light and do not hurt an eye again, you had better choose light yellow lenses to prevent blue light.

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.
Acquisition of optometric degrees when buying glasses online
The degrees are mainly got from three places: physical store paid optometry data, hospital optometry data, previous degree (remember or retest). If you are in the hospital for optometry, it should be noted that there must be test glasses to try on, if there are no test glasses to try on, the data is not accurate.
