As some may know, the end of June marks the official start of summertime! That said, July is UV Safety Awareness Month, which means it’s time to gear up. As the sun emerges brighter and days grow longer, it is essential to remember that while we might protect our skin from harmful UV rays, our eyes also require safeguarding. With the sun reaching its peak, July is the perfect time to delve into the importance of UV protection for your eyes and explore which lenses suit your lifestyle best.
While many are aware of the harmful effects of UV rays on the skin if they have ever experienced a sunburn, less consider the damaging effects of the sun on the eyes. Prolonged exposure to UV rays can be highly damaging to the structures in your eyes. This can lead to an increased risk of eye diseases such as cancer, cataracts, and photokeratitis. Photokeratitis can be likened to a sunburn of the eye and is caused by UV rays reflected off water, pavement, sand, or snow (sometimes referred to as “snow blindness”).
Some amount of exposure to ultraviolet rays from the sun is recommended as your body can convert it into vitamin D, however receiving more than the recommended amount of exposure to UV can be unhealthy. Overexposure to ultraviolet radiation can lead to many common eye and skin problems including cancer, so it is important to understand the risk and use protection accordingly.
Fortunately, the National Weather Service and Environmental Protection Agency provide UV Index forecasts that can tell you how high the risk of overexposure is on any given day. The UV index ranges from <2, low risk, to 11+ which is designated as an extreme risk.
If spending extended periods of time outdoors, it is always a good idea to check the UV index and plan to protect your skin and eyes accordingly.
Using eyewear with 100% UV protection can decrease your chance of damage to the eyes due to the sun. This can be included in most eyeglass lenses including clear lenses, Transitions, and sunglasses, offering both clarity and safety in one package.
Wearing a broad-brimmed hat in conjunction with sunglasses can protect your eyes from the harmful effects of the sun by blocking it off your eyes as well as the skin around them.
The sun and consequentially the UV index is highest around mid-day, meaning the risk of damage from the sun is increased during those hours. It is a good idea to plan to stay indoors during these hours if possible or to seek shade with an umbrella.
You’ve likely seen mention of UVA and UVB before on sunscreens and wondered what the difference was. In fact, there is a third variety of UV as well. These types of ultraviolet differ based on their wavelength, which coincidentally can impact how they affect your body.
UVC rays have the shortest wavelength of the three types of UV. While they could be the most damaging form of UV, the shorter wavelength also means that our atmosphere is able to block UVC radiation from the sun, so in most instances it is not something to be concerned about. However, it is important to remember that man-made UV sources such as tanning beds, mercury lamps, and welder’s torches can still emit this radiation.
UVB rays have wavelengths longer than UVC rays, but shorter than UVA. These rays are known for their ability to penetrate the outer layer of skin, the epidermis, darkening or burning the skin. They have also been linked to various skin cancers.
These are the longest of the UV rays. Due to this, our atmosphere has the most difficulty blocking them and they account for 95% of the radiation that reaches the earth’s surface. Due to their longer wavelength, these can penetrate deeper into the layers of the skin causing sun damage, various cancers, and aging of the skin.
As an eye care provider, we understand that every individual has unique needs and preferences when it comes to eyewear. That is why we offer a diverse range of lens options to cater to various lifestyles. Here is a breakdown of some of our most popular choices:
Polarized Lenses: Ideal for those who spend ample time outdoors, polarized lenses are specifically designed to reduce intense glare. Whether you are hitting the beach or hiking along sunny trails, these lenses offer clarity and comfort while shielding your eyes from harsh reflections.
Photochromatic Lenses (Transitions): Versatile and convenient, photochromatic lenses seamlessly adjust to changing light conditions when exposed to UV light. Transitioning from clear indoors to a darker tint in sunlight, these lenses provide optimal visibility in any environment, ensuring a comfortable visual experience throughout the day.
Polycarbonate Lenses: Engineered for durability and safety, polycarbonate lenses are lighter and more impact-resistant than standard plastic. Perfect for active individuals, children, and sports enthusiasts, these lenses offer reliable protection against both UV rays and potential impacts.
Here at Thomas Eye Group, we prioritize your satisfaction. Our eyewear policy includes a one-year limited warranty on frames, covering manufacturer defects like peeling, cracking, or broken hinges. While accidental damage is not covered, we strive for your peace of mind. Additionally, our lenses come with a 90-day unconditional warranty, allowing two prescription changes and frame exchange if you are unsatisfied initially. Your comfort and satisfaction are paramount, and we are dedicated to providing exceptional service to all of our patients.
