Why should you take care of your rimless glasses?

Rimless glasses are not supported by the outside of the lens frame but are supported directly by the temples of the glasses.Because rimless glasses only rely on both sides of the temples directly with the lens joint, with less protection of the lenses ring. It is easy to cause lens wear, screw loose, so special attention should be paid to maintenance.


Why are blue light glasses yellow?

The material of the lens makes it turn yellow. If it's just blue and the lens is yellow, that's the material itself. Blue light glasses can weaken blue light entering human eyes. Blue light is mainly produced by mobile phones and computers in life. The blue light on the electronic screen is unchanged, so a film can only be designed on the lens to absorb blue light. This can effectively reduce blue light. The complementary color of blue light is yellow, so the yellowing of the anti-blue lens is normal. The material of an anti-blue light lens can effectively shield the blue light. If the blue light is removed from the white light we usually see, it will show yellow, which is a normal phenomenon.



How Do Bifocal Glasses Work?

After learning some basic information about bifocal lenses, you should know how the bifocal glasses work.

With a pair of bifocal glasses, it would be convenient since they combine all your vision needs into a pair of glasses and you do not need to switch two pairs of glasses frequently. Bifocal glasses are usually designed to for those people who are over the age of 40-45 that need additional help with their near vision due to the effects of presbyopia where the crystalline lens inside the eye naturally begins to lose its ability to focus on near objects.

If you work in the office, you may need a pair of bifocal glasses. The top distance vision in the top of the lens can be used for meetings or presentations and the near vision in the bottom of the lens can be used to look at the computer screen or at documents.


Wear blue light glasses before bed.

Because blue light can have a huge impact on your sleep cycle, these glasses are pretty important before bed. So, putting on blue light glasses before you go to bed can help increase melatonin, which in turn helps you get a good night's sleep. Sleep glasses display a wider range of blue light, which naturally helps you sleep better and triples melatonin production. They have a slight lens color because they target a wider range of light, but are best for sleeping. In addition to sleep glasses, there are nearly transparent optical glasses that filter out blue light levels to help treat digital eye strain, which is made up of headaches, blurred vision, and eye strain.



Rimless Glasses

This kind of glasses does not have a frame to wrap the eyeglass ring, only the metal nose pad, and temples, and the lens is fixed after being punched, which is relatively lighter. This kind of glasses is lighter and more fashionable and is the first choice for ladies in the workplace.


Benefits of Progressive Lenses

Progressive lenses are different from traditional reading glasses and bifocal glasses in that bifocal reading glasses have to constantly change the focal length, causing fatigue. And there is no clear dividing line between the two focal lengths. They are more comfortable, more beautiful. When you see far or see near, a pair of glasses can be done, so they become the best choice for old people little by little.

Progressive lenses allow multiple fields of view to be merged into a single lens with no discernible difference between the fields themselves. Degrees of the lens vary gradually from far to medium to your full reading. This is why progressive lenses are often regarded as no-line bifocals or trifocal points.



Adolescents and adults with myopia

Teenagers have heavy learning tasks, and excessive eye use is the norm, so pseudomyopia is the majority. And many of them have false and true myopia coexistence. As adolescents grow and hair, the eyeballs are also developing, and the wheelbase may be further lengthened, so myopia will continue to progress and deepen. The use of mydriatics by adolescents can force the ciliary muscles to relax and eliminate pseudomyopia. But after the pupil is dilated, the ciliary muscles will also lose their ability to adjust, changing from 'nearsightedness' to 'hyperopia', which will delay daily learning. And after the efficacy of the drug has passed, if you continue to use your eyes unscientifically, pseudomyopia will still occur. Therefore, the mydriatic agent is only used as an auxiliary method to eliminate false myopia when wearing myopia glasses, not as a treatment method for myopia.

Adult myopia is based on true myopia. In addition, the eyeballs of adults will no longer develop, so the degree of myopia is relatively fixed and rarely changes.
