Polarized lenses protect the eyes from glare caused by highly reflective surfaces, like snow, water, and asphalt. This glare strains the eye and makes it difficult to see clearly. To combat this, polarized sunglasses have a special chemical coating on their lenses. This works like the vertical slats on a fence or the tightly packed bars on a window: it blocks horizontal light rays and reduces glare.
They Don’t Block Reflected Light
When the sun shines onto a flat surface, such as water, glass, snow or ice, it reflects at an angle. This reflected light causes glare, which makes it difficult to see.
Polarized sunglasses block this reflected light, making it easier for you to see clearly. This is a great benefit for anyone who spends a lot of time outdoors or in bright light conditions.
Polarized lenses also help protect your eyes from harmful UV rays. These rays can cause cataracts and macular degeneration, which are serious eye diseases.
They Don’t Enhance Colors
The most important thing to remember about non polarized sunglasses is that they don’t enhance colors. This is because they reduce the amount of light that passes through them.
In addition, non polarized lenses don’t provide as much UV protection as polarized sunglasses. This can be a concern if you spend a lot of time outdoors and need to protect your eyes from the sun’s UV rays.
If you’re a golfer, you might find that color-enhancing lenses are easier to read the greens while playing. These lenses are designed to reduce overall light while enhancing specific parts of the color spectrum, like blue and greens.
These lenses are great for certain activities, like driving and skiing. However, they can make it harder to see ice patches on the road or in snowy conditions, so you might want to stick with non polarized glasses.
They’re Easier To Read LCD Screens
If you wear polarized sunglasses while trying to read an LCD screen, you may notice that the display appears dark or even black. This is because polarized lenses block horizontally polarized light from screens.
This happens because polarized screens contain polarizing filters, which are designed to reduce glare from bright sunlight. When polarized sunglasses are worn, the screens’ polarizing filters work in reverse and cut off any horizontally polarized light, creating a dark or black screen.
Non polarized sunglasses, on the other hand, allow horizontally polarized light to pass through them, and thus they do not affect the color of the screen. This is why they’re easier to read on LCD screens than polarized sunglasses are.
In addition, they also protect your eyes from the blue light emitted by screens, which can cause eye strain and fatigue. If you need to spend a lot of time looking at digital screens, non polarized sunglasses are your best option.
They Don’t Impact Depth Perception
One of the most important visual skills is depth perception. This is a way to judge distance, as well as other things such as the size and shape of objects. When you lack depth perception it can be difficult to make accurate decisions while on the golf course, in a car or at work.
For example, when you’re driving a motorbike or skiing it’s important to see any water or snow hazards before they become too deep to be avoided. However, wearing polarized sunglasses can interfere with your ability to see them, making it more difficult to determine the safest way to respond to them.
If you wear glasses for sports and find that polarized lenses interfere with your depth perception, you can try non polarized ones instead. They won’t block the reflected light from the sun, but they will increase contrast and enhance colors to help you view things clearly.
Conclusion
Non polarized sunglasses are a great way to protect your eyes from the sun’s damaging UV rays. They also reduce fatigue and help alleviate eye strain. However, they can make LCD screens like phones and airplane screens hard to read. That’s why it’s best to opt for polarized sunglasses for your outdoor adventures.
