There are significant differences between blue light-proof myopia glasses and non-blue light-proof myopia glasses in many aspects, mainly including lens function, light filtering effect, visual comfort, lens color, price and applicable scenarios.
1. Lens function
Blue light-proof myopia glasses: have special coatings or materials that can filter out some bands of blue light, especially high-energy visible light that may cause harm to the human eye. This type of glasses can not only correct vision, but also provide additional blue light protection.
Non-blue light-proof myopia glasses: usually only have the function of correcting vision, and there is no additional filtering layer to reduce the impact of harmful blue light on the eyes.
2. Light filtering effect
Blue light-proof myopia glasses: can effectively absorb short-wave blue light that is invisible to the human eye with a wavelength below 400 nanometers, thereby reducing visual fatigue and other discomfort symptoms caused by it.
Non-blue light-proof myopia glasses: cannot filter blue light, so they cannot provide protection against blue light.
3. Visual comfort
Blue light-blocking myopia glasses: Because they can filter some blue light, the wearer may feel more comfortable, especially after using electronic products for a long time.
Non-blue light-blocking myopia glasses: They may be more likely to cause visual discomfort, such as dry eyes and fatigue.
4. Lens color
Blue light-blocking myopia glasses: The lens color is usually transparent or slightly yellow, which is caused by special coatings or materials.
Non-blue light-blocking myopia glasses: The lens color is mostly colorless or light-colored.
5. Price
Blue light-blocking myopia glasses: Due to their special functions and materials, their prices are usually relatively high.
Non-blue light-blocking myopia glasses: The price is generally lower and more economical.
6. Applicable scenarios
Blue light-blocking myopia glasses: Suitable for people who need to stare at computer or mobile phone screens for a long time for work or entertainment to reduce the risk of visual fatigue.
Non-blue light-blocking myopia glasses: Suitable for people who have less contact with electronic devices on a daily basis, or wear them in non-electronic screen use environments.
In addition, for people with high myopia, color distortion or dizziness may occur when wearing anti-blue light glasses. Therefore, when choosing whether to wear anti-blue light glasses, it should be decided according to personal actual needs and living habits.
