How much does it cost to add the blue light filter to glasses?

Based on the difference in the impact of blue light of different bands on the human body, the blue light transmittance of each band of the product is separately required. For example, in the range of 415-445 nanometers, the light transmittance should be less than or equal to 80%, and above 445 nanometers, it should be greater than 80%. In this way, the anti-blue light products can be restricted, which can effectively shield the blue light that poses a health and safety risk to the human body, but also allows the blue light of the waveband that regulates the human body's circadian rhythm to be effectively transmitted.

Anti-blue glasses are not suitable for everyone. It is only suitable for people who use electronic products for a long time, not for people who are visually fatigued, and teenagers should not wear them for a long time.

About celluloid glasses

In 1929, the first large-scale production of sunglasses made of celluloid was made by SamFoster, an American who ran a women's accessories company facing bankruptcy and made it convenient to use the injection molding technology used to make hairbrushes. Sunglasses made of celluloid were sold on the beach of Grand West, New Jersey, and became very popular. Indeed, celluloid glasses were once popular because of their high-cost performance, but celluloid gradually faded out of people's eyes due to its poor chemical stability, flammability, and other shortcomings, with the emergence of new materials for glasses.


Should I wear glasses all the time for myopia?

Wearing glasses is more to correct your vision and protect your eyes, so as not to worsen myopia. If you are nearsighted but don't wear glasses, it will have a lot of impact on your eyes. First of all, after a person is nearsighted, seeing distant things requires a lot of adjustments to the eyeballs, which will make your eyes tired easily. Over time, your myopia will increase quickly. When we are nearsighted, sometimes the myopia of the two eyes is not the same. If we do not wear glasses and correct vision, this will affect the normal development of vision. The difference between the powers of the two eyes may become larger and larger, which is easy to cause a squint. After myopia, if you want to see far away things clearly, you need to squint your eyes harder to see clearly. Therefore, some nearsighted eyes often squint when they are not wearing glasses. However, the action of squinting will cause the upper eyelid to form a pressure on the eyeball, and squinting for a long time can easily cause amblyopia. Squinting your eyes for a long time will also make your eyes smaller and affect your appearance. Therefore, once your myopia exceeds 200 degrees, you must wear glasses in time.



Progressive lenses and single vision lenses

Single vision lenses are the most commonly used prescription lenses. This lens type has a single field of view or a prescription ability of the entire lens and can be used to correct myopia (nearsightedness) or hyperopia (supervision).

Progressive multifocal lenses are lenses with different upper and lower powers for the upper part to see far, and the lower part to see near. The distance from the fixed power above the lens to the fixed power below the lens does not change suddenly, but there is a gradual transition between the two through the gradual change in refractive power.
