Polarized eyeglasses are hugely popular because they reduce glare and protect your eyes from the sun. However, they can cost more money than regular eyeglasses, so you want to make sure you get what you pay for. You can test the anti-reflective technology of polarized eyeglasses by examining a reflective surface, comparing two eyeglasses, or using your computer screen.
1. Find a reflective surface that produces reflections when the light illuminates it. You can use a reflective dish, mirror or other flat, glossy surface. Ensure that the blind is visible, even at a distance of approximately 60 to 90 cm.
If you need to produce glare, you can turn on ceiling lights or a flashlight on a reflective surface.
2. Hold your eyeglasses approximately 15 to 20 cm (6 to 8 inches) in front of your eyes. You must be able to see the surface through one of the lenses at the same time. Depending on the size of the lenses in your eyeglasses, you may need to bring them closer to your face.
3. Turn the eyeglasses up at an angle of 60 degrees. Your eyeglasses should be inclined at this point, with one of the lenses slightly higher than the other. Because eyeglasses are polarized in a specific direction, their rotation can make polarization more efficient.
Depending on how the glare touches the surface, you may need to adjust the angle of the glasses slightly to see a noticeable difference.
4. Look through the lens and check the level of glare. If the sunglasses are polarized, you will notice that the glare disappears. When you look through one of the lenses, it should be very dark and you should not see glare, but you will always feel that the light is shining on the surface.
If you are unsure about the effectiveness of polarization, move the eyeglasses a few times to compare your usual image with what you see through the eyeglasses.
HOW POLARIZED EYEGLASSES WORK
Reflected light tends to move in uniform directions, either in horizontal or vertical planes, creating glare. Polarized eyeglasses filter or block light waves that are reflected horizontally or vertically (usually horizontally), reducing glare. They do not block all the polarized light, only the light that is aligned with the filter. The rest goes through. Therefore, when wearing polarized glasses, you can reduce glare by tilting your head to change the angle of light reflection.
For example, although dark, non-polarized eyeglasses (normal eyeglasses) tend to reduce the intensity of light coming from all directions in comparable amounts, polarized lenses tend to ELIMINATE the reflection of the light. light from a direction or plane. In other words, polarized eyeglasses work very well by reducing polarized reflection (horizontal or vertical light reflection), effectively eliminating them, but they don’t eliminate all light in all directions.
It is also important to note that only polarization does not protect your eyes from UV rays. However, many polarized lenses are now associated with an ultraviolet blocking substance to provide both glare and ultraviolet light protection.
When you buy polarized eyeglasses, you want to check the label on the glasses or consult your optometrist to check if the lenses offer maximum UV protection in addition to polarization.
SHOULD YOU BUY POLARIZED EYEGLASSES?
If glare reduction is important for your daily activities, you should at least consider using polarized eyeglasses. They are not only popular, but also trendy and elegant. And in combination with UV-blocking substances, they can offer you the UV protection you need.
But they will not reduce all reflections and are not recommended in certain circumstances, especially if you regularly have to display LCDs or even your smartphone, GPS or ATMs. When the screens of these devices are seen by polarized lenses, they tend to disappear, so you have to remove your glasses to see them!
If you have never worn polarized eyeglasses, you should definitely try them. They are especially useful for motoring, motorcycling, extreme sports, water sports and fishing. Polarized prescription eyeglasses are definitely available for those who need prescription glasses! Protect your eyes and vision this summer with polarized eyeglasses. You will not regret it!
