How polarized glasses can help you drive
The most important thing about polarized sunglasses is that they can be a good helper when you drive. When sunlight hits your eyes at an awkward angle, these sunglasses will save your life and save you from potential accidents. Polarized glasses can filter out the sunlight reflected from objects such as roads, snow, water, and other objects. It helps to neutralize the effects of reflected sunlight. Polarized sunglasses bring you an incredibly safe driving experience, with almost no interference and no harm to your eyes.
At night, glare and embarrassing lights are everywhere on the road, especially because random drivers come from the opposite side. Some of these driving high beams may disrupt your vision and cause potential accidents. Polarized sunglasses help reduce glare and save your life. Polarized lenses hardly reflect.

What Are Plano Lenses?
Plano lenses are simply optical lenses which provide no corrective power. That is to say. Plano lenses are eyeglasses lenses that provide no vision correction. They are in widespread use as protective equipment or safety spectacles designed to protect against eye injuries caused by flying dust, metal, wood chips, and other particles.
What Does Plano Mean for Glasses?
If you need a pair of plano glasses, you will see the term plano, PL or 0.00 in the Sphere box on your eye prescription paper. That means that the lens has no corrective power. If only either of your eyes requires correction, you may be given a pair of glasses that as one corrective lens for the affected eye and a plano lens for the unaffected eye.
The function of eyeglasses cloth
Under a powerful microscope, the fibers of the cloth are more closely arranged than those of ordinary cloth, and the material itself is softer than ordinary cloth. That's because eyeglasses under the eye are almost always coated, with each standard lens having seven layers of different functions on the front and back surfaces, to extend lens life. It can thoroughly remove the stubborn stains left on the lens to make the picture clear. It can clean all kinds of glass, resin, and other materials of glasses, glass mirrors, and other mirror surfaces, remove stains, and grease absorption.
Refractive index of spectacle lens
It is generally believed that the higher the refractive index, the better the spectacle lens. Such spectacle lenses are relatively thin, and of course, the price is a bit expensive. When the refractive index increases, the direction of the light entering the lens will change greatly, the focus will move to the lens, the focal length will be smaller, and the diopter will become larger. In order to keep the diopter unchanged, it is necessary to reduce the curvature of the lens, that is, to reduce the curvature of the mirror surface, so that the thickness of the lens can be reduced. This is why the larger the refractive index, the thinner the lens is. Under the same premise of other things, the larger the refractive index, the thinner the lens, the lighter and more beautiful the lens, and the higher the price, but the larger the refractive index is not the better.
Buy Glasses For Kids - Appropriate Frame
To choose a frame for the child, we must first consider the measurement of the bridge of the nose of the child, and the pupil distance. Furthermore, if the eye is farsighted and the pupil distance is too large, it will produce the prism effect from the bottom out. If it is myopia and the pupil distance is too large, it will produce the prism effect bottom-inward. If the pupil distance is too small, it will have the opposite effect. The frame should be light, light glasses will not affect the development and shape of the child's nose bone.
Polycarbonate vs Plastic Lenses: Which One Is Better?
From the above information, you may have learned some features of polycarbonate glasses and plastic lenses. So, do you know which one is better?
Here are some a few differences between both lenses to determine which one is better.
- Polycarbonate lenses are more expensive than plastic glasses.
- Polycarbonate lenses are very resistant to tint compared with plastic lenses which accept tints.
- Polycarbonate glasses have inherent UV protection, while plastic lenses do not have.
- Polycarbonate glasses have higher impact resistance and offer greater protection than plastic lenses.
- Polycarbonate glasses are lighter than plastic glasses.
- Plastic glasses have a higher optical clarity than polycarbonate lenses.
So, from the above part, you may have learned which one is better and you may have a decision of how to choose.
