Each pair of glasses has its own size.
People began to shop for myopia glasses online, but because of lack of experience, many times the size of glasses is not appropriate. At this time they used to complain about the business or glasses. It is really because that they do not see the size of the frame. Just like our clothes and shoes, each qualified frame has its own size. Usually, the size will be marked on the inside of the temple or the bridge of the nose. The manufacturer will clearly mark the width of the frame, the width of the bridge of the nose, and the arm length of the glasses.
Identify the lenses of discount glasses
Look at the overall package: let him show you the overall package of the lens. See that if the factory is in China, Shanghai, China, or Zhejiang, China, etc. Look at the anti-counterfeiting logo. It doesn't necessarily mean it's good. Check the production plant, address, news, etc. In short, lens judgment, for the average consumer, is difficult, but when you put forward these requirements, the store will at least think you are more professional.

When were the first glasses invented?
No one knows when the first pair of glasses were invented, but we do know that the grinding techniques for making simple magnifying glasses have been around since 1000 AD, especially in regions where glasses were already produced (including northern Italy). The earliest artwork of glasses appears in the Treviso Cathedral fresco painted by Tommaso de Modena in 1352. There is reliable evidence that eyeglasses were invented in Italy in the late 13th century. The first pair we think of as eyeglasses appeared in Italian pizza in the late 12th century and looked more like two small magnifying glasses (made of raised glass) riveted together at the top of the handle. In 1266, The English Franciscan Monk Roger Bacon wrote about the scientific principles of corrective lenses, but there is no evidence that he applied this knowledge to the manufacture of eyeglasses.
The price of prescription glasses
You need a current (unexpired) prescription to order glasses online. You will enter your prescription and select the available lens options during checkout. Prescription glasses start at about $40. Single vision lenses are free when you buy the frames, and progressive wireless lenses typically cost an extra $80 or so. Other lens options include clear lenses with no extra charge, basic tone lenses (for sun protection) with the price of $40,polarized-tone lenses (for protection and glare reduction)with the price of $50, and transition lenses (for indoor and outdoor use) with the price from $65.
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.
