Blue Retina

Blue Retina

LEDs produce blue light which can damage the retina of the eye. Basically, humans do not recognize blue light as dangerous, so we don’t react to strong or excessive blue light exposure by turning away or blinking.

Unfortunately, blue light makes an LED look clean and bright to our eyes. It’s a cheap, and dangerous, way to make a low-powered LED look brighter than it really is (compared to natural white light). High quality LEDs come with test reports showing the wave lengths of the light spectrum they emit.

This is an important source of information Atexor uses to select LEDs for its luminaires. High-powered LEDs produce strong light in any case, so filtering blue light needs to be considered.
