As the weather warms up, it's crucial to protect your eyes from UV radiation and sun glare. Wearing proper eye protection helps prevent vision problems and damage from sun exposure.
UV radiation, what is it
Ultraviolet (UV) radiation is a type of optical radiation that originates from the sun. It falls on the invisible spectrum, with wavelengths ranging from 100 to 380 nanometers (nm). The properties of UV light can pose a risk to the eyes if proper protection is not used, just as UV rays from the sun can harm the skin without adequate sunscreen.
UV radiation is split into three different types: UVA, UVB, and UVC. They are based on the measure of their wavelength. UVA rays have the longest wavelength.
What is sun glare
Sun glare refers to solar radiation within the visible light spectrum, specifically wavelengths ranging from 380 to 780 nm. This glare can hinder our ability to see clearly in bright conditions, often necessitating the use of sunglasses or appropriate shade. When the sun’s glare reflects off water or other shiny surfaces, it can pose significant risks for individuals driving or operating machinery. Additionally, it can cause damage to the eyes.
Why protect against UV radiation and sun glare
Optical radiation can cause eye damage in a variety of ways, depending on the wavelength and specific characteristics of the radiation. Visual problems resulting from UV radiation and sun glare are usually temporary, but they can lead to long-term complications. UV radiation exposure can result in partial or total blindness, which can happen suddenly or develop over time. Photokeratitis, an inflammation of the cornea, can also be caused by UV radiation, with snow blindness being an extreme manifestation of this condition.
Protecting against sun glare is also essential for preventing accidents and injuries. Solar radiation not only can cause significant eye damage but can also impair a worker's vision, increasing the risk of trips, falls, and more serious injuries when operating machinery.
Safety glasses, goggles, and face shields are all available with UV protective lenses. Eye protection with UV protection are indicated by "U" followed by a number (e.g., U2-U6), with higher numbers signifying greater UV protection. Markings with U2-U6 indicate the average UV transmittance, with U6 providing the most UV protection.
For the highest level of protection, select lenses with a UV400 additive that filters UV light in the 400 nm range.
Which products provide sun glare protection?
For protecting eyes from sun glare, safety glasses offer a wide variety of lens tint choices. Lens shades are denoted with an "L" followed by a number indicating darkness level (e.g., L1.3, L1.5, L2, L2.5, L3, or higher). Higher numbers mean darker lenses and correspond to lower luminous transmittance.
Eyewear UV protection and safety compliance can be easily verified by examining specific markings on the glasses. These codes indicate protection levels and standards met, ensuring eyes are safeguarded against harmful UV radiation and sun glare. Easily recognizable identifiers allow users to quickly assess protective capabilities.
Protecting your eyes from UV radiation and sun glare is essential for both immediate comfort and long-term visual health. Selecting appropriate eyewear not only safeguards your eyes but also enhances safety and productivity in everyday activities. Prioritize certified eye protection to maintain clear, healthy vision through every season.
