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.

How to Keep Glasses from Slipping
Stick-on Nose Pads
Nose pads would be a good choice to prevent glasses to slide down your nose. Hence, you can stick a pair of rubber pieces in the nose pads of your glasses or you can choose a pair of glasses with rubberized nose pads. If you want to try a pair of nose pads glasses, the Koalaeye Optical may be a good choice. The rubber nose pads will make you feel steadier and better and the additional resistance on the nose pad will surely provide more support. So, if your glasses often slip down from your nose, try this way.
Wax Coating
To keep glasses from slipping, you can try wax coating which is a smart move. Use the wax on your nose pad area along with the temple where the glasses come into contact with the skin. In general, it works fine and it is nearly invisible.
Temple Ear Hook
The temple ear hook is a good way to keep glasses from slipping. It can provide mechanical support behind the ear and you will feel the support from the back of your ears. But the drawback of the temple ear hook is that it is quite visible. When you take off the lenses, you need to lift the temple higher so that the ear hook could clear the ear’s crest. Besides, the cheaper one might cause some discomfort to the back of your ears because of the pressure.
Rubber Bands and Hair Ties
To keep glasses from slipping, you can also try hair ties and rubber bands. You can tie one around the temple tip behind your ear so that it can provide both slight mechanical support and friction forbidding your glasses from moving around. What’s more, this is a low-cost method.
Geek 111 Glasses
The Geek111 is a unique, yet timeless frame containing decorative metal plaques. The metallic trim makes it a stylish combination, and for this frame, there are several different colors to choose from, including black, brown, and gray. They can easily add anti-reflective coating and/or different lens colors so you can be more confident when driving at night.
How Should Glasses Fit?
In order to enable the glasses to fit on your face and ears, you need to pick the right frame width for your face. The width of your frame is the entire horizontal measurement of the front of your frames. A correct frame width will ensure your eyes are properly aligned in the center of your lenses for optimal vision. The frame width should be slightly wider than your face but with the space between your temple and frame no larger than a finger’s width.
Moreover, you also should ensure the Arm Length is right for you. The arms of glasses should run along with your temple and wraps around your ears. The arms should run horizontally and sit comfortably around your ears only touching your head right before your ears. Of course, you can find the arms-length of glasses on the side of the temple.
