What is a progressive lens?
A progressive lens is a lens whose upper sides are used to see far, and the lower side is used to see near. The distance from the fixed distance power above the lens to the near power fixed below the lens does not change suddenly, but a gradual transition between the two through the gradual change in refractive power.
Standard progressive lenses are multifocal lenses with three observation areas, farsightedness, intermediate vision, and nearsightedness. Unlike bifocals, there are no visible lines between each viewing area. They have a seamless, invisible design, where the optical power changes 'gradually' throughout the lens. Many people confuse 'bifocal' or 'trifocal' with 'progressive' but remember that bifocals and trifocals have visible lines in the lens, while progressive lenses do not. Because progressive lenses have no lines in the lens, they are more popular multifocal lenses than bifocal lenses. However, is progressive lens good for eyes?

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.
