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.
Comfortable wearing experience
Fine workmanship is the key to the details of pure titanium glasses. Whether you have an oval face or a round face, you can adjust the width according to the size of your face, and maintain this state, so that there will be no more scars around your eyes and ears.
Nowadays, people's living standards are getting higher and higher. Pure titanium glasses have become more and more popular with many people. Especially for mid-to-high-end business elites, pure titanium glasses have become a fashion, and are even more respected. Pure titanium material is lighter and more comfortable among glasses materials, not easy to be deformed, corrosion-resistant, and rust-resistant, and will not cause skin allergies. It is the most high-end high-quality spectacle frame in all kinds of spectacle frames.
What Are Gaming Glasses?
Gaming glasses are designed for people who play video games on computers or gaming systems. Many gamers and e-sports competitors spend long periods in dark room and the blue light from the screen can affect their eyes. However, if they wear gaming glasses when playing computer games, they can protect their eyes because they provide anti-reflective coating, magnification, and blue light protection.
Gaming glasses with anti-reflective coating helps to reduce glare, which is light that reflects back into your eyes from a digital device. Reducing the amount of glare can help to make eye focusing easier, improve color contrast and potentially increase your reaction time.
Many gaming glasses add a small magnification power to their lenses, which can reduce squinting and eye strain.
The gaming glasses can also help to block blue light and improve your body’s circadian rhythm and improve your sleep quality.
So, you can find that gaming glasses are beneficial to your eyes. However, do gaming glasses work?
What Is Anti Reflective Coating?
Anti reflective coating, also known as AR, anti-glare, no-glare, or glare-free coating, can provide benefits to your vision. Anti reflective coating is added to lenses to reduce glare caused by light hitting the back of the lenses to improve your vision and make your eyeglasses more visually attractive.
Anti reflective coating will eliminate all reflections from the front and back surfaces of your lenses. Hence, more light is able to pass through your lenses which improves your vision. At the same time, fewer distractions are visible and the lenses are hardly noticeable, especially in the dark. So, is anti glare worth it? Most people agree that.
Disadvantages of bifocal glasses
The disadvantage of bifocal glasses is that the different areas are clearly spaced and the appearance is not beautiful. The medium distance is fuzzy, and the adaptation period is needed, there is a prismatic jumping phenomenon. The focal distance between the upper and lower lenses is different, with a clear dividing line. The main disadvantage is that when the line of sight moves from far to near, there will be interference like jumping, and the middle distance object image is blurred. Students can adapt to sitting still in a class by wearing bifocal glasses, but they can only wear glasses when they are in class or studying because of the inconvenience and even danger caused by the interruption of the glasses.
Dark-rimmed glasses with wider frames
When choosing dark frames for round faces, one should pay attention to the width of the frames. If dark frames give people a feeling of narrowing, then the frames will appear smaller. Small frames make your face look bigger and rounder, so choose frames that are wide. If you can't wear a wide frame because the lenses are too strong, skip black and opt for something lighter.
How to test a blue-light lens?
Blue-light-blocking lenses are now focused on refractive indices of 1.56 and 1.60. If you buy lenses that are not of either refractive index, be wary. Of course, with the development of technology, now some brands have produced 1.71 refractive indexes blue-light-blocking lenses, suitable for people with high myopia to wear. The true lens package should at least have the product name, refractive index, dispersion coefficient, transmittance, color, SPH, CYL, and other indicators. These indicators are perfect, can be treated as the reference basis of the formal product. In addition, you can go to a professional optical shop or testing institutions for testing.
