The Cons of Transition Lenses
However, besides the pros of transition lenses, there are also some negative voices of transition lenses.
The transition lenses are not effective in cars because the windshield blocks the UV rays so that transition lenses won’t darken very well in the car.
Different brands of photochromic glasses have different levels of darkness and different reaction times. So, you may need to ask the doctor to find the brand that works best for you. Transition glasses are affected by colder weather. So it means that it may take a bit longer to react to UV rays in winter. Most transition lenses are not polarized which may result in harsh glares.
So, if you need transition glasses, try Koalaeye Optical, which provides the Koalaeye photochromic glasses. Besides these, Koalaeye Optical also provides other kinds of glasses, such as blue light blocking glasses, polarized sunglasses, progressive sunglasses, and so on.

Features of pure titanium glasses frame
Due to the lightweight (ordinary nickel-based alloy frame weight 48%-60%), high strength, corrosion resistance, surface easy coloring, beautiful and durable features of spectacle frame made of pure titanium, they have been loved by most consumers. But the elastic modulus of pure titanium is higher (about 120GPa). The temples of the frames made from them are not elastic enough. After wearing the glasses for a period of time, the temples of the glasses need to be adjusted due to the relaxation of the stress. The processing plasticity of titanium metal is worse than that of other metal materials, so the processing technology of its wire is difficult. The surface quality is difficult to control, and the technical content is high. The surface quality of pure titanium wire produced by a few domestic manufacturers is poor.

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.
