Understanding the Impact of Light Radiation on Cataracts: Zenni’s EyeQLenz

Light radiation exists along a spectrum that extends beyond what is visible to the human eye. This spectrum includes ultraviolet (UV) and infrared (IR) radiation, which carry different levels of energy. While UV radiation is known to cause damage to the skin and eyes, recent research has shed light on the role of IR in thermal damage and cataract formation. Exposure to IR can be found in daily life and with high intensity radiation in industrial settings such as glass and steel industries.

Uncovering the Effects of Infrared Radiation
Recent studies have delved into the mechanisms through which IR contributes to cataract formation. One study investigated the impact of near-infrared (808 nm) radiation on the eyes of pigmented rabbits. Exposing the eyes to IR at this wavelength resulted in morphological changes in the anterior segment of the eye, particularly the formation of cortical cataracts.
Understanding the Mechanism of Infrared Radiation
During IR exposure, the temperature in the anterior chamber, a fluid filled space between the cornea and the iris, begins to increase, particularly in the region next to the exposed area of the iris. This increase in temperature is attributed to the absorption of IR energy and its conversion to heat within the iris. The heat is then conducted to the lens of the eye, leading to the development of cataracts. These findings align with H. Goldmann’s theory dating back to the 1930s, which suggests that heat-induced damage contributes to cataract formation.

The Impact of UV Radiation on Eye Health
Ultraviolet (UV) radiation, which is present in sunlight and artificial light sources, has been linked to various eye conditions, including cataracts, pterygiums, and macular degeneration. UV radiation is divided into three categories by wavelength: UVA, UVB, and UVC. Prolonged exposure to UV radiation can lead to oxidative stress and damage to the lens of the eye, contributing to opacification and the development of cataracts over time.
Protecting Against Radiation with EyeQLenz
One way to mitigate the risk of cataracts caused by light radiation is through protective eyewear. Zenni offers EyeQLenz, which is a culmination of the latest technology designed to block both UV and IR radiation. By incorporating advanced technology into the lenses, these lenses shield your eyes from harmful radiation while maintaining clear vision. Investing in eyewear with EyeQLenz can provide peace of mind and protect against the long-term effects of light radiation exposure. In addition to UV protection and IR protection, other features of the EyeQLenz include:
- Photochromic Technology: These lenses are light adaptive and can darken in response to increased light exposure in a matter of seconds.
- Blue Blocking Technology: EyeQLenz are fitted with Zenni’s blue blocking technology to decrease symptoms of computer vision syndrome.
