Ray-Ban Wayfarer Ease Optics
Perhaps the most famous square glasses on the market are the Ray-ban hikers. These glasses add a classic, cool style to your look. If the line is thick, select black. If you have a lot of colors, go for Havana red. Similar to rectangular glasses, square glasses are best for round or oval faces.
The weight difference between pure titanium frames and titanium frames
Titanium frames are slightly heavier than pure titanium frames, but they are both high-quality materials, so they are more comfortable on the outside. The specific gravity of pure titanium is generally 4.5, while titanium alloy is 8.9, which means the material is equivalent to half of the titanium alloy. So the frames are lighter in your hand.

Can the TR90 frame be changed?
TR90 material was originally made in Italy. It is difficult to color the frame, and usually, the color is painted on the outside. It can float in saltwater. It is suggested that the lens should be a water first to prevent overheating of the lens. Then, at the end of the nose, hinge, or the temple, carefully fold it in until it is comfortable to wear. You can use a household hair dryer to blow heat first, which can play the role of softening. Note that the hairdryer should be moved when heating, and do not aim at only one place. TR-90 is the most popular ultra-light material in the world at present.

Adolescents and adults with myopia
Teenagers have heavy learning tasks, and excessive eye use is the norm, so pseudomyopia is the majority. And many of them have false and true myopia coexistence. As adolescents grow and hair, the eyeballs are also developing, and the wheelbase may be further lengthened, so myopia will continue to progress and deepen. The use of mydriatics by adolescents can force the ciliary muscles to relax and eliminate pseudomyopia. But after the pupil is dilated, the ciliary muscles will also lose their ability to adjust, changing from 'nearsightedness' to 'hyperopia', which will delay daily learning. And after the efficacy of the drug has passed, if you continue to use your eyes unscientifically, pseudomyopia will still occur. Therefore, the mydriatic agent is only used as an auxiliary method to eliminate false myopia when wearing myopia glasses, not as a treatment method for myopia.
Adult myopia is based on true myopia. In addition, the eyeballs of adults will no longer develop, so the degree of myopia is relatively fixed and rarely changes.
