PROTECT YOUR PATIENTS

0

It’s been determined that exposure to certain portions of the blue light spectrum can cause discomfort and even impact overall eye health. With blue light emitted from the sun as well as from the screens that have become ubiquitous in our lives in the form of smartphones, computers and televisions, our eyes are being bombarded with harmful wavelengths.

Visible blue light is found in the wavelengths between 400 and 500 nanometers, but not all blue light is created equal. Researchers have identified particular wavelengths as contributory to specific conditions and health effects. Reports support the association of the lowest end of the spectrum (380nm to 455nm) with the development of age-related macular degeneration. A recent study demonstrated loss of retinal cell viability with maximum effect between 415nm and 455nm. Some sources cite an even narrower band, from 420nm to 440nm, as being hyper-critical.

The upper end of the blue spectrum has a marked and well-documented effect on human circadian rhythms, the biologic clock that controls sleep/wake cycles. The range of light that most affects photoreceptors in the eye that influence circadian rhythms, known as melanopsin retinal ganglion cells, is from 459nm to 485nm.

In response, manufacturers and optical labs have introduced many products to protect patients from certain portions of the spectrum (see chart below). While a wide range of coatings and lenses with embedded protection are listed here, there are plenty of other products available.
