ATTCL Retro Polarized Night Driving Glasses
These glasses have metal frames. The metal frame uses an aluminum-magnesium alloy structure, strong and light. While you'll see them available in a variety of colors, you'll still have to choose the night vision option if you want to buy night driving glasses. The anti-glare yellow night lens is designed to filter 20 percent of glare at night.
Benefits of Blue Light Glasses
In this section, we will show you the benefits of blue light glasses.
- Relieve eye discomfort with blue-light blocking glasses. Excess device usage can lead to computer vision syndrome or digital eye strain. Blue light glasses can enhance your focus and reduce eye strain, resulting in making your eyes feel less tired and improving productivity. Another way to reduce eye strain is to make sure you take regular breaks from the screen.
- Blue light glasses can affect your sleep. Blue light has a high energy frequency that can increase alertness and delay the body’s release of melatonin, which helps induce sleep. In general, you had better not use blue light devices one to two hours before sleep. Blue light glasses can reduce the impact of blue light, enabling you to use your devices before bed and still get a good sleep.
- Blue light glass can help reduce the likelihood of Age-Related Macular Degeneration. AMD is a leading cause of blindness. Blue light blocking lenses can help avoid or delay this condition by preventing blue light from impacting your eyes.
Of course, besides those benefits, there are some other benefits of blue light glasses. For example, blue light glasses can relieve headaches.
Round Glasses
While round glasses have been popular for the past few years, this season, metallic round frames from the '80s and 90s are getting more attention. These days, round glasses aren't just for Harry Potter fans. People add a sense of weirdness or fashion to their appearance. If you have an angular face and a chiseled chin, then round glasses are for you.
Points To Note When Choosing Frames
Choose a frame with lightweight, good elasticity, and stable structure. The lens frame with poor quality tends to deform in use, which affects the optical properties of the glasses. Pay attention to whether the two sides of the frame are symmetrical and whether it is fixed and safe enough. Pay attention to whether there are scratches on the surface of the frame. Just put on the glasses to feel if it is very tight or very loose, and they must be tight to reach the saturation condition. Pay attention to distinguish the advantages and disadvantages of the coating. The better coating frame has a uniform color, smooth surface, and clear identification. After using the frame with poor coating quality, the frame will soon rust and fall off, affecting the life of the frame, and even causing skin discomfort or allergy.
How to buy plano lens?
You had better not buy off-the-shelf plano lens, buy by fixed matching, just like matching with myopic glasses. The price is much more expensive than the finished product. However, the quality of the finished glasses is not guaranteed, and the materials are also poor, which is not only not helpful to you, but harmful for a long time. There is no essential difference between degrees and workmanship technology for the lenses, what should choose is the brand lens film of the lens, and the transmittance of the lens, and the design technology of the lens, to buy a good lens (including smooth lens).
The extraction of titanium
Nowadays, the commonly used extraction method is the reduction method of titanium tetrachloride. Compared to copper and zinc, although high in content, much more expensive. On the other hand, China is the country with the largest reserves of titanium, and a large number of steel mills with perennial overcapacity began to produce titanium, so the price of titanium fell year after year.
Types of Optical Frame Glasses
The full-frame glasses have good strength, suitable for athletes and children to wear because the lens is completely protected by the lens ring. They are suitable for a variety of refractive parameters of the lens. The upper part of the lens ring is made of metal or plastic materials. The lower half of the lens ring is made of a very fine nylon wire like the lower part of the lens ring. Rimless glasses are lighter than full-frame glasses. Rimless glasses can be divided into parts type and integral type. The part type consists of a nose bridge (together with the nose pad) and two temples. The combination glasses are divided into two parts. Usually, the front group is equipped with colored lenses, and the rear group is equipped with lenses for correcting refractive errors. The folding glasses can usually be folded at the bridge of the nose and the temple to reduce the space when stored or carried and are mostly used for making reading glasses.
