How to tell if your sunglasses are good quality
One of the main reasons to wear sunglasses is to protect your eyes from the sun’s harmful rays. However, are you sure that your sunglasses are giving your eyes the protection that they need? There are many ways that you can tell if your sunglasses are of good quality and are protecting your eyes properly. At Mountain Eye Care in Hamilton, ON, we carry sunglasses from some of the industry’s most popular and quality brands. When you come to us for prescription sunglasses, you can have peace of mind knowing that your eye health is in the best hands. In this article, we share some information about how you can tell if your sunglasses are of good quality.
Look for the UV protection label
Trusted sunglasses brands will always indicate the type of UV protection on their labels. It’s either you’ll come across labels that indicate 100% UV protection or the UV filter category UV 400. Sunglasses with a UV 400 lens block all light rays with wavelengths of up to 400 nanometers, which covers all UVA and UVB rays.
Test your sunglasses with a UV flashlight
If you have a UV flashlight at home, you can use it to test your sunglasses’ quality. Shine the light against any paper money. When the watermark from the bill lights up, put your sunglasses in front of it. If it disappears, it has UV protection. Apart from releasing UV light, which your eyes can not see, the flashlight will also release visible light. If you try this experiment on your sunglasses and you find that the UV protection is not satisfactory for you, then a visit to Mountain Eye Care is needed!
Understand what polarization means
Polarized sunglasses are becoming more and more popular to have and for a good reason. Polarized lenses are equipped with a filter that only lets vertically-oriented light pass through and blocks horizontally-oriented light. When this happens, it reduces glare, enhances contrast, and improves visual clarity and comfort. Although polarized lenses are not essential for blocking the sun’s UV rays, they are an added protection for your eyes that allow clearer vision in the sun, which can be especially useful when driving or doing certain sports.
There are plenty of other things that you can do to make sure that your sunglasses are of good quality.
