This topic is for future product design improvement suggestion, open for debate. 3Dconnexion can/may consider change the color of the LED to long wavelength color light to protect 3Dconnexion end-users' vision.

Blue Light and Your Eyes You should know that blue light can cause an eye damage. Practically all visible blue light passes through the cornea and lens and reaches the retina. This light may impact vision and might too soon age the eyes. Early research study shows that excessive exposure to blue light could result in:

Digital eyestrain: Blue light from computer screens and digital devices can decrease contrast resulting in digital eyestrain. Fatigue, dry eyes, bad lighting, or how you sit in front of the computer can cause eyestrain. Symptoms of eyestrain consist of sore or inflamed eyes and problem focusing.

Retina damage: Studies suggest that ongoing exposure to blue light in time could cause harmed retinal cells. This can cause vision problems like age-related macular degeneration.
