Do you need to wear glasses to drive?
In the evening, lights from street lamps, buildings, and other vehicles create a lot of reflection on the windshield, making it hard to see. It's even worse when it rains. But if your glasses have an anti-reflective coating, they can reduce the glare and reflections, allowing you to see more clearly while driving at night.
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.
When do you need blue-light-blocking glasses?
Anti-blue light glasses are suitable for wearing when using LED digital display devices like TV, computer, PAD, and mobile phone. However, it is not recommended to wear anti-blue light glasses for a long time in daily life, because the anti-blue light glasses filter part of the blue light and the picture will be yellow when viewing objects. It is recommended to wear two pairs of glasses, one pair of ordinary glasses for daily use. A pair of anti-blue light glasses to use for computers and other LED display digital products.
Charmant glasses
Japanese Charmant Group is one of the world's famous eyewear manufacturing enterprises. Since its inception in 1956, it has always been the leader of cutting-edge technology in the field of eyewear manufacturing. Charmant is a global titanium expert, and now the domestic market has launched 7 series of titanium, like Z titanium, etc., to meet the Chinese consumers’ pursuit of all ages for high-quality glasses and more comfortable glasses.
Among them, EX titanium is a patent developed by Charmant Group. Compared with common memory titanium, EX titanium has a more stable memory function and a more diversified design.The frame price of Charmant glasses is 1000 yuan above basically, from 1000 to 4000.
How to Adjust Glasses If They Pinch Your Nose
In some cases, glasses will pinch your nose, so you also need to adjust them, too. If the glasses frames are metal, you should simply widen the plastic nose pads using your thumbs until the frames fit comfortably. If the glasses frames are plastic, you should soak the arms of your glasses in warm water for 30-60 seconds, and gently apply upward and outward pressure on the end of the arms to get a more relaxed fit.
After that, your glasses will become more suitable.
Unfortunately, not all glasses can be adjusted by yourself at home. You can’t adjust some glasses which are based on the material of your glasses. For example, the glasses with the following material can’t be adjusted at home:
1. Aluminum alloy.
2. Memory plastic.
3. Titanium or memory titanium.
If your glasses are made of these materials, you can’t adjust them by yourself at home. If something goes worse, you need to buy a new pair of glasses. It is also risky to adjust the rimless or semi-rimless glasses by yourself at home.
As for how to tighten glasses or how to adjust glasses, you may have brief knowledge after reading this post. If your glasses are already broken or you want to get a pair of new glasses, you can try Koalaeye Optical, which is cheap and has a free shipping service.
The Optical Center of A Lens
When wearing glasses, try to look through the optical center of the lens. This needs the cooperation of the neck, you can slightly lower the head when looking at the computer, to adjust the line of sight. The Center of optical glasses is divided into two kinds: 1 mm up myopic lens center is the most proper, of course, more than 2-3. And the most important thing is that the lens pupil high (about the two-lens optical center of the high and low) must be proper (that is, the right of the lens optical center is 1 mm, the left must be 1 mm. 2-3 mm is the same, what is the height of the pupil on the right side must be the same on the left side. The optical center of the presbyopic lens is 1 mm, the most proper.
What are the causes of lens damage?
When the force area of the lens is small, the impact resistance of the lens is worse. When subjected to the impact of external forces, the lens will naturally be squeezed and cause breakage.
In particular, some lenses with low degrees and high refractive index are possible to cause this phenomenon. When the frame fell from a height due to wrong placement, there is a collision between the edge of the lens and the ground or hard objects. It will produce a broken or collapsed edge. In the process of the lens falling from high, the impact force is larger, and the stress point is smaller. When the glasses are falling, the upper edge of the lens, the convex groove of the upper frame, squeezes against the lens. The middle part of the upper half is easy to cause edge collapse. In the process of processing the template, the template is not accurate, so that the glasses side and the frame can not be uniform fusion, and the force of the lens is uneven. It will be easy to lead to greater stress in some parts, resulting in edge collapse.
