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.


The style of prescription glasses

Choose the material, and then choose the style. The width of the appropriate frame should match the distance between the two pupils to ensure that the eye can pass through the optical center when looking at things. Choose the right style according to your face shape. Generally follow the complementarity principle, such as choosing square frames for round faces and round frames for square faces. After choosing the frame, you should try it on for a while to see if the weight is appropriate and the style is suitable.



How do you identify the refractive index of lens?

In reality, this problem is often a problem for optical shop practitioners, sometimes they worry about whether the manufacturer's lenses match the nominal value of the refractive index. We need a prop, and that's the camber. Because it can be used to measure the strength of the lens. The luminosity of the lens can be calculated by subtracting the curvature of the inner and outer surfaces of the lens. The curvature difference of a lens of the same luminosity is inversely proportional to the refractive index, that is, a lens with a higher refractive index only needs a smaller curvature difference to achieve the same luminosity.


Benefits of Progressive Lenses

The lens looks like a single vision lens, with no dividing line between degrees. Not only is it beautiful in appearance, but more importantly, it protects the privacy of the wearer's age (for the wearer of reading glasses). There is no need to worry about showing the secret of the wearer's age by wearing the glasses. Because the degree is gradual, the replacement of the adjustment effect is increased step by step according to the shortening of the close distance. There is no adjustment fluctuation, which is not easy to cause visual fatigue. Clear vision can be achieved at all distances in the visual scope.



Do Blue Light Glasses Work?

When wearing blue light glasses, you may ask whether the blue light glasses really work. In fact, many users have the same troubles. To answer this question, some researchers have made research and have found that blue light glasses make it possible to remain fully engaged in our technologically advanced world, without taking on the negative effects of blue light.

With the blue light blocking glasses, you can focus on the task at hand without negative effects. Besides, with the blue light blocking glasses, you can even sleep well and reduce eye strain. You can also test your blue light glasses are real.


What are night driving glasses?

Night driving glasses, also known as night vision goggles, are available in many optical shops or online shops. The color of the lenses ranges from pale yellow to amber, and some night driving glasses also have anti-reflective coatings.

Night driving glasses reduce glare by scattering and filtering blue light. Blue light is the light with the shortest wavelength in the spectrum and is more likely to cause glare when it enters the eyes. Night driving glasses are usually non-prescription glasses with yellow lenses. They usually add some kind of anti-reflective coating to eliminate reflections from street lights and oncoming headlights, which can cause glare.

These yellow night driving glasses have been manufactured and sold for decades. It was originally sold to hunters as shooting glasses. Because in cloudy or overcast conditions, they can make the contrast between the birds and the sky more vivid.



Alloy glasses frame

Spectacle frames made of the alloy have relatively high hardness, are more resistant to friction, are not easy to fade, have a better texture, and are made of more styles, which are essential for fashionistas.
