The Pros of Titanium Glasses

First, titanium is used in its pure form and as an alloy to provide a highly flexible eyeglasses frame. In fact, titanium eyeglasses are flexible. So, they are able to bend without breaking and can return to their original shape.

Second, titanium glasses come with good durability. Titanium alloy metals produce the world’s most durable eyeglasses frames. Choose a titanium frame and it will be nearly impossible to break.

Third, the titanium glasses are extremely lightweight. They are about 40% lighter than the standard steel glasses frames. In addition, due to the superior strength of the titanium frame, the frames can be made thinner making for even lighter frames.

Fourth, titanium glasses have hypoallergenic properties. It is rare anyone experiences adverse skin reactions to titanium frames. There are many other options on titanium frames such as color, texture, and patterns. What’s more, titanium glasses are corrosion-resistant.

So, are titanium glasses worth it? You may have the answers.


How To Choose Better Night Driving Glasses?

You should select light alloy material and polymer material with memory, collision resistance, and low friction coefficient characteristics. It can effectively prevent the damage to the eyes and face caused by the friction of the broken lens frame during use. Because of its specific molecular structure, the chemical resistance is good. In the high-temperature environment. it is not easy to deform and can withstand 350 degrees in a short time of high temperature, not easy to melt and combustion. The glasses made of this material are light and strong, and the ears will not be uncomfortable because of wearing the glasses for a long time.



What Are Progressive Lenses?

Progressive lenses have grown in popularity and are one of the most common solutions to treat vision loss that occurs with age or presbyopia. This eye condition occurs when the eye loses some of its flexibility and ability to adjust to clear seeing objects at different distances. Presbyopia often occurs among adults who are over age 40 and is very easy to correct with a proper and prompt diagnosis.

Progressive lenses are often used to correct this eye condition. Progressive lenses are a modern alternative to bifocal glasses, which provides two prescriptions in a single set of glasses. Bifocal glasses are a better solution than carrying around multiple pairs of glasses. Progressive lenses were developed to resolve some of those common issues and to provide better aesthetics. Progressive lenses provide a smooth transition and can accommodate up to three prescriptions and are a replacement for both bifocals and trifocals.


Pay attention to the wearing of myopia sunglasses when driving.

Some drivers are slightly myopic, usually driving without wearing a myopic mirror. There is no problem. But once you wear sunglasses, the problem comes: your eyes are more likely to tire and your vision will decline, just as your driving vision will be affected at night. Therefore, for the driver of slight myopia, there is no problem in usually driving, but if you want to wear sunglasses, you must be equipped with the lens of myopia degrees.



What is an MR lens?

MR is the brand name of optical lens raw materials produced by Mitsui Chemicals in Japan. MR series is available in three different refractive indices (1.60, 1.67, 1.74): MR-7, MR-8, MR-10, and MR-174. MR-7 and MR-10 have higher thermal deformation temperature and excellent dyeing, which are widely used in the field of sunglasses. MR-8 has the most balanced performance index and is suitable for the production of lenses of any strength. It has the highest market share in lens materials with a refractive index of 1.60. MR-174 is a high refractive index lens material, which is mainly used in the production of ultra-thin lenses.


Advantages of carbon fiber glasses frames

The main reason for choosing carbon fiber to replace traditional plastic and metal materials is that carbon fiber has the characteristics of lightweight and high tensile strength. Spectacle frames made of carbon fiber materials are significantly lighter than traditional metal spectacle frames. In addition, such spectacle frames are impact resistant, has high hardness, wear resistance, are not easy to deform, and will not fade. Also, the carbon fiber material has good biocompatibility and is often used in medical equipment, so it will not cause allergic reactions, and it is not easy to corrode and rust. The lightweight carbon fiber frame is easy to carry, and it is not easy to deform the bridge of the nose when worn on the bridge of the nose, relieves the burden on the nose and ears, is not easy to slip, and is comfortable to wear.

Why are blue light glasses yellow?

The material of the lens makes it turn yellow. If it's just blue and the lens is yellow, that's the material itself. Blue light glasses can weaken blue light entering human eyes. Blue light is mainly produced by mobile phones and computers in life. The blue light on the electronic screen is unchanged, so a film can only be designed on the lens to absorb blue light. This can effectively reduce blue light. The complementary color of blue light is yellow, so the yellowing of the anti-blue lens is normal. The material of an anti-blue light lens can effectively shield the blue light. If the blue light is removed from the white light we usually see, it will show yellow, which is a normal phenomenon.
