Why are titanium glasses so expensive?
Strong and Durable. They are widely used in aerospace technology, jewelry, surgical instruments, and other fields. It is the most progressive material in the eyewear industry. Titanium is a very hard, lightweight metal that is proper for eyeglass frames. With good hardness, high strength, the glasses are not easy to deform. It is not easy to scratch and wear and has good corrosion resistance and plasticity. It has a high melting point, corrosion resistance, and hard electroplating. Titanium can be made into memory metal, which means it can bend and return to its original shape. Hinge is not easy to break, having rust resistance, impact resistance. When it's used in glasses, it fits the bill.If you've ever broken a frame, titanium is possible the best material for you.
What Are Varifocal Glasses?
Varifocal glasses, also known as varifocals, varifocal lenses, or progressive lenses, have a gradual change in strength from the top of the lens to the bottom with multiple focal points in between. Unlike bifocals, varifocals glasses have no specific area of lens strength, but progressive lens zones.
As mentioned above, varifocal glasses have three different prescriptions in one pair of glasses, allowing you to correct near and far vision. So, they bring you great convenience since you don’t need to change the glasses frequently.
However, there are also some common problems with varifocal glasses and we will show you the disadvantages of varifocal glasses.
So, in the following section, we will show you the disadvantages of varifocal glasses.
What are the benefits of memory metal frames?
Memory metal materials are inherently lighter than metal materials, which can reduce the pressure on the bridge of the nose and skin. The memory metal frame is super elastic, so it never deforms, and it is so apparent that the temples on both sides of the frame line up with the ring. Because the bending can be automatically restored to its original state, the stability is comparatively strong. It has the benefits of high-temperature resistance, corrosion resistance, which will not cause skin allergy, and so on. It is a hypoallergenic lightweight metal for eyeglass frames that is strong and flexible. It is resistant to corrosion, making it proper for people who work, live or play sports in all kinds of outdoor weather conditions. The memory metal can be placed on the side of the face, making it easier and more comfortable to wear. The memory temples can freely rebound 180 degrees without deformation, making up for the insufficient effect of elastic β titanium. This kind of frame is not able to recover due to careless bending, and it has the function of restoring shape itself.
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.
Do blue light glasses actually block blue light?
Anti-blue light glasses are still popular on the market. This kind of glasses is said to be 'anti-radiation and anti-blue light', but this kind of hot-selling anti-blue glasses has many problems. At present, such anti-blue glasses mainly block or absorb blue light through special materials, but there are two misunderstandings in its blue light protection. One is that the protection is not preventable, and the other is that the color cast caused by the wrong protection makes visual fatigue aggravated. Studies have shown that our eyes are the most intolerant of blue light in the 400nm to 440nm band. Therefore, current manufacturers mainly block blue light in this band when producing anti-blue glasses. But the electronic products that we often come into contact with nowadays produce blue light between 450 nanometers and 490 nanometers, and anti-blue glasses have almost no protection in this wavelength. Generally speaking, the blocking rate of anti-blue glasses is 20% to 30%, but now the blocking rate of anti-blue glasses on the market basically reaches 80% to 90%. This high blocking rate can also easily cause a color shift. , It is easier to make the eyes tired.
Can clear lenses be polarized?
At present, there are no clear polarized lenses. A polarized lens is a thin film vertically arranged with silicon crystal coating placed inside the lens, just like a shutter, which covers the parallel light and only allows the vertical light to pass through. In this way, the glare from all directions can be eliminated, so it is clear and comfortable to wear. Transparent polyamide, the material of nylon lens, is a new variety of polyamide. The material of the nylon lens is mainly transparent polyamide. Due to the effect of the light filter, only light from a specific direction is allowed to pass through the lens, which filters the dazzling light from the sun on the water, land, or snow very well. It can not only make the landscape soft, clear, and natural but protect the eyes to a certain extent.
Can you wear glasses with swimming goggles?
One potential solution to blurry vision while swimming is to wear prescription glasses under your goggles. While this can be effective in improving vision, the biggest problem is that if you wear glasses under your glasses, your goggles don't fit tightly to your face, which means your eyes get water. If you try to fix the problem by tightening the goggles around your glasses, you could break something that would cost hundreds of dollars to replace.
