Sunglasses with 100% UV protection are designed to block 100% of harmful ultraviolet (UV) rays from the sun. These rays are invisible to the naked eye and can be damaging to both the eyes and the skin. There are three types of UV rays: UVA, UVB, and UVC.

UV protection must be put on your sunglasses at the time they are manufactured. Adding it to your sunglasses as an afterthought is just not done. If you bought your Polarized Sunglasses in Canada, then they likely already have UV protection. It’s just not legal to sell sunglasses without UV protection in Canada. If you would like the level of UV protection checked, Bring them to Doig Optometry and we can check them for you. If you have an ophthalmic quality sunglass frame, and you want to put new lenses in it, we can make sure your new lenses are UV blocking, Polarized, or both, according to your preference.

Which is better UV orpolarizedsunglasses

The width and height of lenses do not affect the ability of the lens to block ultraviolet rays, but larger lenses give you better coverage so less sunlight can get to your eyes and face around the sunglass frame.

When choosing polarized sunglasses, make sure to get them from reputable brands and retailers to ensure the lenses effectively block glare and provide the intended benefits.

Sunglasses labeled as providing 100% UV protection are equipped with lenses that block both UVA and UVB rays. The lenses contain special coatings or additives that filter out these harmful rays, preventing them from reaching your eyes and reducing the risk of eye damage and related issues.

Two types of sunglasses are 100% UV protection and polarized sunglasses. In this article, we address the important differences between the two.

Pros and cons ofpolarizedsunglasses

Glasses with UV protection should be clearly marked. Check for a label that indicates “100% UV Blocking”, or something similar. Glasses with a 100% UV protection or UV 400 label block both UVA and UVB rays. If you are still in doubt, ask the eyecare professional helping you choose your glasses. UV protection comes standard with every pair of glasses we sell at Doig Optometry.

Glare occurs when light waves from the sun or other sources reflect off a flat surface and become aligned in a horizontal pattern. This concentrated, intense light can be uncomfortable and harmful to the eyes, causing eyestrain and reducing visibility. Polarized lenses work by blocking these horizontally oriented light waves while still allowing vertical light waves to pass through.

UV-blocking sunglasses protect your eyes from dangerous ultraviolet rays and are crucial to good eye health. Polarized sunglasses can make your eyes more comfortable by eliminating glare. Whether you are deciding between simple UV-blocking sunglasses or Polarized Sunglasses, one of our friendly and helpful team members will help you find the best lenses for you.

Expert Tip: Digital screens emit polarized light, so Polarized Sunglasses block out parts of the image and are not ideal for digital devices.

While you should choose sunglasses based on your needs and style, the adverse health effects of UV exposure make protection against harmful UV rays the priority. While glare can be bothersome, it does not lead to harmful health effects. You should seek out glasses that have both properties. At Doig Optometry, UV protection comes standard with every pair of sunglasses.

The polarizing filter in the sunglasses lenses is usually a chemical film that is vertically aligned. When horizontally polarized light hits the filter, it cannot pass through, effectively reducing the amount of glare that reaches your eyes. Eliminating this horizontally polarized light enhances visual clarity, reduces eye strain, and improves overall comfort when dealing with intense light conditions.

Howdo polarizedsunglasses work

Polarized sunglasses are particularly popular among outdoor enthusiasts, such as fishermen, boaters, skiers, and drivers, as they help to provide a clearer view of their surroundings and improve safety. However, it's essential to note that polarized sunglasses may not be suitable for certain activities, such as viewing LCD screens or some instruments, as the polarization can interfere with these displays.

Since there are no negative health effects from glare, there’s no legal requirement that your sunglasses eliminate glare. Patients who still experience light sensitivity in their UV-blocking sunglasses sometimes think that their sunglasses aren’t dark enough. However, it’s more likely that the remaining light sensitivity is actually glare sensitivity, which can be eliminated with a quality pair of polarized sunglass senses.

Light sensitivity comes from two sources: UV exposure and glare. Since there are negative health effects from Ultraviolet light exposure, all sunglasses sold in Canada must be UV-blocking by law. That’s not necessarily true at the swap meet on your tropical holiday, though. The good news is that UV Protection is part of every pair of Sunglasses purchased at Doig Optometry. We can also ensure that your clear eyeglasses are UV-blocking.

Expert Tip: A common misconception about sunglasses is that they should only be worn in the sun, but it’s equally as important to wear sunglasses in the shade as UV rays reflected from other surfaces are also dangerous.

Polarized sunglasses are a type of eyewear specifically designed to reduce glare from surfaces like water, snow, glass, and other reflective surfaces. They achieve this by incorporating a special polarizing filter into the lenses.

Ultraviolet light causes sunburns, so it’s no secret that ultraviolet rays can be harmful. It’s also no secret that too much exposure to ultraviolet light over time can cause changes in the skin and even skin cancer. But did you know that ultraviolet light can also affect your eyes? Studies have shown that prolonged exposure to UV rays can lead to:

Now that summer is upon us and we’re all spending more time outdoors, it’s good to remember that the eyes need protection from UV light. Since Ultraviolet light exposure is almost always greater at higher altitudes, and since Calgary is at a moderately high altitude (1,048 meters, or 3,438 feet), it’s even more important where we live.

Expert Tip: Polarized Lenses eliminate reflections from the surface of a puddle on the road, creating a risk for motorcyclists and cyclists. Elite golfers who judge the lay of the green by the reflection of the surface of the blades of grass will notice that this is more difficult to see while wearing Polarized Lenses that eliminate these reflections.

Calgary enjoys an average of 333 days of sunshine each year, totalling 2396 hours. That’s a lot of sunshine to make us feel light-sensitive! This highlights the importance of having adequate eye protection while we’re out enjoying the sunshine and warm weather.
