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.


The glasses are too loose or too tight at the temple.

If your glasses are too tight on your temples, you will feel uncomfortable. On the other hand, if your frames are too loose, it can make you look not energetic. Either way, you can adjust the frames at home to make them more comfortable. If the arm squeezers your temples. If the frames are metal, hold your lenses in place with your less-used hand. Use your dominant hand to gently press outwards on the corner of the frame, between the hinge of the frame and the lens. Repeat this step on the other side of your body to make your temples looser. If the frame is too loose from the temple. Again, for metal frames only, use the same method as you used to relax the frames, but apply slightly inward pressure on the corner between the hinge and the lens. Repeat on the other side, tightening the fit around the temple. Adjusting the temples of rimless, half-rimless, or plastic frames can break them. You are advised to take these frames to the optical shop for adjustment.



How To Choose Better Night Driving Glasses?

You should select light alloy material and polymer material with memory, collision resistance, and low friction coefficient characteristics. It can effectively prevent the damage to the eyes and face caused by the friction of the broken lens frame during use. Because of its specific molecular structure, the chemical resistance is good. In the high-temperature environment. it is not easy to deform and can withstand 350 degrees in a short time of high temperature, not easy to melt and combustion. The glasses made of this material are light and strong, and the ears will not be uncomfortable because of wearing the glasses for a long time.

Should I buy prescription glasses online?

Selecting reputable sellers for online shopping glasses is the key to ensuring quality. If you are worried about the quality of online shopping glasses, my suggestion is to choose a reputable, high-quality seller. Usually, online shopping will have an evaluation section. Therefore, you can also refer to the evaluations of other consumers. In addition, by comparing products of the same price, choose the most cost-effective one.



Testing of aspheric lens

The optical axis of the optical center just overlaps with the visual axis of the eye, which is the most ideal state. Because the light from the edge cannot form a focus on the optical axis, when the optical axis does not overlap with the visual axis (the difference is greater than 2mm), such unclear and scattered imaging results will occur. When choosing frames and aspheric lenses, you need to ensure that they fit correctly, to achieve the best visual and decorative effects. Simply put, due to the special design of the lens, we found through a calculation that the optical center should move down 1mm higher than the pupil for every 2° increase in front inclination angle. Otherwise, the wrong pupil height will cause the lens to look like astigmatism, and cause discomfort. For glasses with aspheric lenses, there must be an inclination angle after wearing. The specific angle varies from person to person.
