Sun Protection for the Eyes: Prevent Eye Injuries, Cataracts, ARMD, Surfer’s Eye

sun protection glasses hat sunscreenThe sun sustains life, but it also can harm our eyes. Unsafe sun exposure causes or may contribute to several eye conditions and diseases.

Therefore, we must take extra precautions to prevent cataracts, age-related macular degeneration, ocular melanoma (eye cancer), and eye injuries such as pterygium (Surfer’s Eye), photokeratitis (snow blindness), and flash blindness. The sun is also a driving hazard when low on the horizon.

The body contains its own “sunscreen,” which is melanin. Dark-skinned people have more melanin and

LumiThera Develops Treatments for Vision Loss from Macular Degeneration

limthera deviceA low-level light treatment called photobiomodulation may be a future treatment for macular degeneration. A company called LumiThera is developing devices for treating vision loss. The devices expose the eye to low-level laser light or light emitting diodes to stimulate cellular function. This is called low level light therapy (LLLT). It is distinct from surgical or aesthetic laser treatments, which destroy tissue.

Visible or near infrared light (NIR) light is produced by a laser or a non-coherent light source. This therapy is in wide use by chiropractors, physiotherapists and sports medicine professionals to treat
