Why do you need to wear safety goggles correctly?
Eye strain occurs when muscles are tired from strenuous exercise (from tension to concentration), similar to what happens to other muscles in the body from strenuous exercise or overuse. Eyestrain is the result of eye pain and fatigue, often accompanied by headaches. Eye strain has a lot to do with the quality of your glasses. If you wear cheap and inferior safety glasses for hours at work, you will feel uncomfortable. While your eyes won't be permanently damaged by fatigue, it can affect your productivity.
Why are eyeglass frames are so expensive?
Good frames and bad frames are very different just in how they feel. The bigger the brand company, the more money it invests in the design, research and development, production equipment, and equipment of the lens frame every year, so as to improve the wearing comfort and improve the combination and precision of the lens. Even if for the general assembly line, the processing process is also very complicated. The most expensive things to make by hand are labor and time.
The refractive index of the lens is related to the thickness of the lens.
The main factors that determine if a pair of finished glasses are beautiful, portable, and comfortable depending on the thickness and thinness of the processed lenses. Depending on the material, the index of refraction is different. If you just look at the refractive index, the higher the refractive index at the same degree, the thinner the lens will be. The thinner the lens will be, and the more beautiful the lens will be. However, the higher the refractive index, it is not the better. You can choose the refractive index lens suitable for yourself. But the refractive index is not the only factor that determines lens thickness. Think about the distance between your eyes and the size of the frames you choose, which can affect the thickness of the lenses you match. The larger the pupil distance, the smaller the frame, and the thinner the lens.
Pure titanium spectacle frame
Of course, we still have another option, which is to buy a pair of pure titanium glasses. Pure titanium is lightweight, tough, and compatible with the human body. Also, it has strong corrosion resistance, resistant to rust, does not cause skin allergies, and is more durable. With the gradual popularity of pure titanium materials, the price is gradually becoming more affordable, and people who feel troublesome to wear anti-allergic sleeves can try pure titanium spectacle frames.
Why are titanium glasses so expensive?
Pure titanium can guide the electron wave to produce ions so that the current tends to ionize, and positive and negative ions can reduce the harmful effects of the body's biological current chaos caused by electromagnetic waves. To the human body, it has a great health care role. It avoids fatigue, muscle stiffness, soreness, and other symptoms or problems.
The resurgence of celluloid glasses
However, in recent years, celluloid glasses have quietly returned to warm; It all started with a niche Japanese brand of handmade eyewear.
Most of Japan's top hand-made celluloid glasses are made in Mako Prefecture and are a favorite of many celebrities. Celluloid is a plasticizer with nitrocellulose as the main raw material. Cotton, pulp, and other fibers make up 70% of the raw material, which is mixed with camphor. Although the color is relatively limited, it has a unique material texture and texture, so Japanese handmade frame makers have been insisting on using it. Moreover, because celluloid is pretty stable when it dries, it can be shaped into a finer shape, keeping the frame intact even without metal leg cores.
This unique pattern is the perfect choice for those who want to wear tops and jackets of any color. They fit almost any color. Tortoise glasses come in many colors, and this stylish pattern has a wide palette, so there's no need to worry about skin and hair color. If you want to keep up with current eyewear trends, unique-patterned tortoiseshell glasses are your best bet.
