How Do UV-Blocking Contact Lenses Work?
In today’s world, protecting our eyes from the harmful effects of the sun is more important than ever. With increasing ultraviolet (UV) radiation levels and longer exposure times, our eyes are at greater risk. Luckily, there are contacts made to block UV radiation. So, what are UV-blocking contacts, and how can they help protect your eyes from UV radiation?
Understanding UV Radiation and Its Harmful Effects
UV radiation comes from the sun and includes many types of rays: most importantly, ultraviolet A (UVA) and ultraviolet B (UVB) rays. They may sound similar, but understanding the difference between UVA and UVB rays can make a difference in protecting your eyes.
UVA - longer wavelengths, can pass through cornea and damage the eyes, can cause cataracts and vision loss
UVB - shorter wavelengths, mostly absorbed by atmosphere, can damage the eyes’ surface and cause sunburn
UV radiation doesn’t only come from direct sunlight. UV rays can bounce off of reflective surfaces like water, snow, sand, and even buildings and increase your exposure to them. This can make protecting your eyes an ongoing challenge, but UV-blocking contacts can help.
What are UV-Blocking Contacts?
UV-blocking contacts are specially designed contact lenses that contain UV-blocking agents. They help filter out a large portion of UVA and UVB rays, providing an added layer of protection beyond what sunglasses alone can offer.
These lenses are crafted with materials that have built-in UV protection. This means that when you wear UV-blocking contacts, you’re not only correcting your vision but also preventing harmful UV rays from reaching the sensitive tissues of your eyes. It’s like having an invisible shield that works alongside other protective measures.
However, keep in mind that not all contact lenses come with UV protection. When shopping for contacts, look for labels that specifically mention UV blocking capabilities. This extra feature can make a world of difference in protecting your eyes.
Benefits of UV-Blocking Contacts
UV-blocking contacts can reduce glare, improve visual comfort, and be worn in combination with sunglasses for maximized protection. (We recommend wearing both UV-blocking sunglasses and UV-blocking contacts for maximum sun protection.)
They’re also super convenient. Unlike sunglasses, which you might forget at home or lose when you’re out and about, UV-blocking contacts stay with you as long as you’re wearing them.
Who Should Consider Wearing UV-Blocking Contacts?
Anyone who spends time outdoors can benefit from UV-blocking contacts, including:
- Athletes
- People who work outside
- People with light-colored eyes
- Children and teenagers
Choosing the Right UV Blocking Contacts
When selecting UV blocking contacts, consult with your eye care professional. They can recommend the best options based on your lifestyle and eye care needs. Some brands, such as Acuvue and Bausch + Lomb, offer a wide range of UV blocking contact lenses for different needs.
Remember to look at the level of UV protection offered by different contacts. Not all UV blocking contacts are the same. Some lenses block up to 99% of UVB rays and 90% of UVA rays, while others give less protection. Make sure to choose the lenses that provide the highest level of UV blocking for your needs.
Also consider the fit of the lenses and your comfort. Many lenses have advanced technologies that can keep your eyes moist and comfortable throughout the day, even if you’re wearing your contacts for extended hours. You don’t have to compromise on comfort while protecting your eyes.
Lastly, check the replacement schedule of the lenses. Some UV blocking contacts are designed to be worn for one day then thrown away, while others are replaced bi-weekly or monthly. Check with your eye care professional to figure out which type of lens fits your lifestyle for the best eye health and comfort.
