How to wear clear frames with style?

A square face is all about softening the lines of the face, so it works well with round frames. The person with a long face should choose a bit bigger frame. It can make the proportion of the face-up and down more harmonious. The oval face is the standard face shape, and any frame is suitable. People with round faces are similar to those with square faces. If you have a round face, you can choose a square frame instead of a round frame, which will only make your face look rounder. The most important feature of a diamond face is high cheekbones, so choose a thick frame to visually weaken the cheekbones. For the triangular face, people can choose the frame of a half-frame design. Since the upper part of the face will be smaller in this shape, a half-frame design is necessary to balance the proportions.

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.



Does blue light cause damage to the eyes?

Businesses often associate blue light with mobile phones and computers that everyone frequently touches. There are also many terrible explanations about blue light on the Internet, ranging from causing damage to the eyes to causing cancer. Therefore, in recent years, mass media and academic circles have caused heated discussions about the possible impact of blue light on eye health.

It is believed that the reason why blue light harms the eyes is that blue light is not like ultraviolet light which is absorbed by the cornea and lens so that it cannot reach the retina. Blue light can reach the retina through the refractive medium of the eye, and over time it will cause the aging and functional degradation of the retina. But in fact, the eyes have many protection mechanisms in the process of evolution, such as squinting, pupil contraction, lutein contained in the macula of the retina, the anti-oxidant repair mechanism of the retina, etc., which can protect our eyes from the damage of blue light. Also, after scientific testing, the blue light emitted by electronic products is a few percent of the intensity of blue light in natural light, which means that as long as the electronic products are not used continuously every day (for example, more than 8 hours a day), blue light will not be causes obvious damage to the eyes.

Polarized vs non-polarized sunglasses

  1. Non-polarized sunglasses generally only have the two basic functions of shielding strong light and filtering ultraviolet rays, and their efficiency in filtering ultraviolet rays is low. In our daily life, in addition to strong light and ultraviolet light, when light passes through uneven roads, water surfaces, and other places, irregular diffuse reflection light will be generated, which will cause blurred vision and fatigue in the eyes.

  2. Polarized sunglasses can filter out this kind of light, only absorb the reflected light of the object itself, truly present what you see, make the field of vision clearer, and reduce visual fatigue. In addition, polarized sunglasses have a 99% blocking rate of ultraviolet rays due to their high-efficiency filter layer, which can effectively reduce the damage of ultraviolet rays to the eyes.

  3. When judging whether the sunglasses are polarized lenses, you can rotate the sunglasses up to 45° clockwise. If the color of the lens changes at this time, and the color of the sunglasses returns to normal after turning the sunglasses back to the original position, then it can be judged that the sunglasses are polarized. And if you can’t see the change in the color of the sunglasses lens no matter how you turn it, then you can judge that the sunglasses are not polarized.
