Cheap sunglasses are everywhere. They are a popular free gift from companies that want to look trendy and are sold in every store anywhere near the beach and other places that people frequent during the summer (such as theme parks). But you should be very, very careful with cheap sunglasses, because even if you feel like they help keep the sun out of your eyes, they can actually do more harm than good. The problem is that cheap sunglasses don't protect against ultraviolet rays, which can cause problems like eye cancer and cataracts. Instead, they trick your eyes into thinking it's dark when it's not, causing the pupils of your eyes to dilate and let in far more UV rays than normal. This greatly increases the amount of damage the sun can do to your eyes. While you might like to use them to keep the sun out, if you do it often, you can seriously damage your health. If you have a cheap pair of sunglasses or get them for free, the best thing to do is throw them in the trash. Of course, the opposite of cheap sunglasses is not necessarily expensive. The sunglasses you want are ones that offer 100% UV protection, but they can actually be very reasonably priced and can last you decades if you're smart about where you put them at the end of summer. come, making them an even better value. You should look for some official certificate that the sunglasses have been tested for both UVA and UVB screening, and only buy from a store you trust, preferably an established pharmacist. On clear days, you will run out of sunglasses. If you don't have one, you can pop into a drugstore or convenience store and pick up a cheap pair so you can be comfortable outside.
But sunglasses are an important form of eye protection that should offer more coverage than just darkness. You need to protect your eyes from exposure to ultraviolet (UV) light and glare, just as you protect your skin with sunscreen. Exposure to certain wavelengths of light can damage several parts of your eye and lead to long-term problems.Cheap sunglasses may advertise that they have UV protection, but they are not specific about UVA and UVB protection. Take the time to research the types of sunglasses and what percentage of UV rays they protect your eyes from. Visible light: Blocking 75 to 90 percent of the rest of the visible light spectrum protects your eyes from glare. If your eyes aren't protected, glare can cause damage, including photokeratitis, which is like a sunburn on the eye.UV Protection: There are two types of UV rays you can protect yourself from – UVA and UVB. These are associated with a higher risk of skin cancer. They can also damage your eyes if too many of these rays hit the inside of the eye. Finding sunglasses that block 99 to 100 percent of both UVA and UVB will help keep your eyes healthy.
