Glasses should not have serious color differences.
Children's eyes are not fully developed, and the eyeball is still growing slowly, at this time it is best not to wear such blue light glasses with the serious color difference. If you always see things with color differences, it will cause eye discomfort, resulting in increased myopia, but the opposite. The big color difference will cause low light transmittance, affecting child macula development. In the case of long-term distortion and discoloration, visual physiology and psychology will be affected.
Blue light glasses for children have special lenses that block some light waves, which may help protect children's growing eyes from digital eye strain. Blue light lenses sometimes have a slight yellow tint. You can buy prescription or non-prescription glasses with child-size frames and lenses that filter blue light. They don't filter out all the blue light, but they can reduce your child's exposure to blue-violet light by 80 percent or more.
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.
Who looks good in transparent glasses?
Transparent glasses look good on almost all face shapes and skin tones for both men and women. Due to their versatility, they can mix and match with almost every outfit on any occasion. They are neither too old-fashioned nor showy among the crowd. You can confidently carry them with your office look and also, there is no problem hanging out with your friends.
What Are Computer Glasses?
Computer glasses or glasses for computer are prescription glasses that are designed to wear when doing computer work. They allow you to focus your eyes on a computer screen. There are other activities such as playing piano or shooting requiring a similar custom fitting.
Glasses for computer use are also known as blue light glasses. They block blue light that causes eye strain due to prolonged viewing of digital screens. Blue light is part of the color spectrum, and everyone is exposed to it through sunlight.
The glasses for computer use have a shorter wavelength than other colors and are emitted by electronic devices such as smartphones, TVs, computers and more. The glare from blue light is what causes digital eye strain or other symptoms. But the glasses for computer can protect your eyes from the damage of the glare.
Depending on an individual’s vision and type of work, there are several options while selecting glasses for computer use.
Monofocal: Monofocal or single-vision glasses are designed for computer work so that they provide the appropriate optical correction for the working distance between the screen and the user’s eye. These glasses allow users to view the whole screen with a minimum up-and-down head movement. However, the disadvantage of the monofocal glasses is that both distant objects and reading materials that are closer than the computer screen will appear blurry.
Bifocal: When it comes to glasses for computer screens, the bifocal glasses would be a choice. Bifocal glasses can be prescribed so that the upper segment is set up for screen distance and the lower segment for work. The disadvantage of these bifocal glasses is that it will blurry if the objects are farther away than the screen.
Trifocal: These trifocal glasses for computers have lenses that combine a segment for far vision, another for near vision and the third one for at the screen distance. The disadvantage of these glasses for computer screen is the limitation to view areas.
Which is better, Essilor lens or Zeiss lens?
1. Different high-density resin substrates. Essilor Diamond Crystal series 1.74 lenses use resin with a density of 1.46 as raw materials. The lens itself has higher hardness. Combined with Diamond Crystal series film layers, the lifespan of the lens is better improved. The outstanding abrasion resistance is obvious.
2. Different technical support. The greater the density of the lens, the harder the substrate. However, the larger the density of the lens under the same volume is heavier. Therefore, Zeiss has the best trade-off between density and component and selects high density on the basis of high refractive index and frivolity substrates.
3. Different Features. The anti-fog molecules on the two surfaces of the lens are activated by an anti-fog activator. Therefore, the fog differentiates into a thin layer that is invisible to the eyes, instead of forming a fog. Each spray of activator can last about a week. Zeiss resin lens guarantees up to 99.4% of the lens light transmittance, and the naked eye can no longer feel whether the lens is worn or not.
Should I wear glasses all the time for myopia?
Whether it is false myopia or true myopia, as long as a pair of suitable myopia glasses are used to complement the missing refractive power of the lens, the image of the object can fall on the retina again, and the distant objects can be seen again. Adolescents usually use high eye intensity and often wear myopia glasses, so that the ciliary muscles do not need to be 'so tired' to adjust, which can avoid further aggravation of pseudomyopia. However, adolescents are still in the process of development, and the degree of true myopia will gradually increase with age. Therefore, as the degree of myopia develops, refraction should be performed at regular intervals, and appropriate glasses for myopia can be prepared to prevent false myopia.
For adults under 200 degrees, because the degree is relatively light, they can wear glasses when they are looking at the distance and not wear glasses when they are near, which has little effect on vision. But for adults with high myopia, because of the weak adjustment ability of the eyes, it is recommended to wear glasses regardless of near vision or distance vision.
In summary, wearing myopia glasses is to reduce eye fatigue and prevents the occurrence of false myopia. Wearing myopia glasses from time to time may aggravate the degree of myopia, and wearing them often does not cause a burden on the eyes. Therefore, for myopia glasses, wearing them frequently is the most correct way to wear them.
