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.

Plano Lenses vs Demo Lenses

When talking about the plano lenses, demo lenses will be talked about, too. Plano lenses are different from demo lenses. Demo lenses are nothing but lenses that are fitted into the demo frames at the optical showroom and workshops. The only purpose of demo lenses is to give a realistic aesthetic of the frame to the users so that they can get an idea of how it would look with corrective lenses. However, there is also no corrective power on demo lenses.

Compared with demo lenses, plano lenses provide good quality lenses that give your protection against harmful UV rays and blue light emitted from digital screens like laptops and desktops. In addition, you can also add an anti-glare coating to the plano glasses.
