Eye protection from UV radiation and sun glare
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.
