How to protect your contact lenses?

When wearing contact lenses, do not drop any eye drops, and only use a special moistening solution for contact lenses. In daily life, we recommend that dry eyes can be relieved with lubricating fluid, but we do not advocate frequent use of lubricating fluid, so as not to make the eyes become dependent on lubricating fluid. The right way is to do blink training. The ingredients contained in the eye drops will remain in the lenses, which will cause certain damage to the eyes and pollute the lenses. Some eye drops can make the lenses tinted after use, which will affect the transmittance and a refractive number of the lenses and make the vision blurred. Ladies who need to make up should wear contact lenses before making up. When removing makeup, remove contact lenses before removing makeup, to avoid the makeup sticking to the lens and damaging the lens and eyes. Lenses should not be lent to others to avoid cross-infection of eye diseases. You can't wear contact lenses while swimming or bathing.

Choose the frame according to the skin color

Generally, people with lighter skin tones are best to choose lighter-colored frames. For darker-skinned people, choose frames with darker colors. For example, people with white skin can choose the frame of soft pink, tortoise color, or golden silver, while people with darker skin color can choose red, black, or tortoise color.


Many traditional optical stores are complaining about a drop in customer numbers. When we analyze it, we find that the decline in customer numbers is divided into two aspects. The first is the decrease in new customers, which is mainly because the Internet and eye hospitals are fighting for customers from optical stores. The other is the loss of old customers, which is entirely because the optical store did not do the best service, especially the after-sales service.



Bifocal Lens

Bifocal lenses have two observation areas separated by visible lines, a larger observation distance area, and a smaller reading area. It may take some time for people who are wearing bifocal glasses for the first time to get used to the lenses. This is mainly due to learning how to move the eyes between the observation distance area and the reading area. Some people will also find that there will be an 'image jump' phenomenon at the visible line between the distance and the reading area, especially for those with limited mobility, who must look down when walking. The best way to get used to bifocals is to wear them as much as possible.


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.

What is the difference between sunglasses and polarized glasses for fishing?

Ordinary sunglasses reduce the sensitivity of the light, reduce the intensity of the reflection, and reduce the glare of strong light. Wear the glasses to see where there is a reflection on the surface of the water, the reflection still affects the vision.

Polarized sunglasses used for fishing can not only reduce the sensitivity but also refract the reflections to prevent the strong light from stabling the eyes. Wearing polarized sunglasses to see the reflections on the water surface will not see the reflections. Also, you can see underwater fish and scenery ( Depending on the clarity of the water), it is not an exaggeration to say that polarizers are an enhanced version of sunglasses.
