To observe whether the lens has scratches, impurities, bubbles, stripes, check the outer packaging of sunglasses, regular sunglasses should be marked with product name, color, diameter, quality level, the name of the manufacturer and trademark, mirror or tag marked with anti-UVA, UVB and CE signs of the sunglasses to ensure that a certain amount of ultraviolet. Hold the corners of the sunglasses against the fluorescent lamp and let the reflective strip of the mirror roll gently. If you find that the sunlight reflected by the mirror appears wavy and distorted, it shows that the lens is not smooth, and such a mirror will damage your vision.
How to choose the right shade of sunglasses for us in summer? A simple way to test yourself is to wear sunglasses in front of a mirror so that you can barely see your pupils. If the color is too light, the filtering effect is too small. Too dark color will affect vision and weaken color sense. Sunglasses of colorful light color that is popular this year, do not use in activity on seaside water, in the snow field that glances strongly and sunshine falls very intense sun, and should wear sport sunglass, they use the saturated color with gorgeous color mostly, can absorb or reflect more visible light.
What is the principle of sunglasses? Sunglasses can block uncomfortable bright light and also protect the eyes from damaging ultraviolet rays. All this is thanks to metal powder filters that “select” light as it hits. The tinted glasses selectively absorb some of the wavelengths that make up the sun’s rays because they use very fine metallic powders (iron, copper, nickel, etc.). In fact, when light hits the lens, it is subtracted by a process called destructive interference. That is, when certain wavelengths of light (in this case UVA, UVB and sometimes infrared) pass through the lens, they cancel each other out on the inside of the lens, toward the eye. The overlap of light waves is no accident: the crest of one wave and the trough of its nearest counterpart cancel each other out. Destructing interference depends on the refractive index of the lens, which is how much light diverges as it passes through different substances from the air, and also on the thickness of the lens. Generally speaking, the thickness of the lens does not vary much, while the refractive coefficient of the lens varies according to the chemical composition.
Touch weariness: Usually the specific gravity of the alloy frame is about 8.9g/cm3, the specific gravity of the pure titanium frame is 4.5g/cm3, because the weight of titanium material is equivalent to half of the alloy frame, it is relatively light by hand. This is one of the easiest ways to distinguish between titanium and non-titanium racks. Hinge joint: The pure titanium lens frame should not be directly in contact with titanium at the hinge part, otherwise it is easy to wrinkle the joint and the lens leg is not open. Two thin spacers are usually inserted into the hinge of a pure titanium mirror to separate the upper and lower hinges. Therefore, check the hinge has no gasket, is also a good way to identify whether it is pure titanium frame. Looking at the joint of the hinge from the inside of the frame, a small groove will be found, which is specially designed to facilitate the removal of the gasket.

How To Tell If Your Sunglasses Are Polarized? So, you’ve bought a slick pair of sunglasses claiming to be polarized, but how can you be sure? Don’t worry; it’s not as tricky as it seems. There’s a straightforward test you can perform to verify whether your sunglasses are polarized. The most common method is the ‘rotation test’. For this, you’ll need a second pair of polarized sunglasses or a polarized lens to test against. Start by holding the two pairs of glasses so that you’re looking through both lenses at the same time. Rotate one pair 60 degrees in either direction. If the overlapping area becomes darker, congratulations! Both pairs are polarized.
Polarized lenses are made by placing a thin film of chemical compounds, usually a type of polymer, between two layers of a lens. These compounds are designed to absorb light of a specific polarization. During the manufacturing process, this film is stretched to align the long chains of the polymer. This alignment blocks light vibrating along the same direction as the aligned polymer chains, filtering out glare. What Polarized Sunglasses Do? Polarized sunglasses do more than make you look cool. They’re your ultimate shield against harsh glares. Remember when we talked about light becoming polarized when it hits a flat surface? Well, polarized sunglasses effectively block this reflected light, ensuring it doesn’t reach your eyes.
Now, the first gem in your glasses-cleaning toolkit should be a lens-cleaning solution. These come pre-made, ready for you to deploy in the fight against dirt. But, if you’re a DIY kind of person, there are plenty of homemade solutions that can do just as good a job. Be careful, though. Make sure you use recipes from reliable sources. After all, you don’t want to accidentally damage your precious glasses. Next up, we’ve got clean clothes. Microfiber clothes are your best friends here. They’re soft, they’re gentle, and they get the job done without leaving a trace of lint. Cotton cloths can also do the job, but avoid rough fabrics that can scratch your lenses. And, whatever you do, don’t use regular paper towels or tissues. They might seem harmless, but they can scratch your lenses.
