Color Blindness Awareness Month is a time to raise awareness about color vision deficiency (CVD) and its impact on daily life. Around 1 in 12 men and 1 in 200 women worldwide experience some form of color blindness, making it crucial for public spaces to consider their needs in urban planning and design.

Vision loss or impairment can be caused by a number of injuries, illnesses, and more. Some cases happen gradually while others occur suddenly. In some situations, vision loss can be easily corrected with eyeglasses, contact lenses, or surgery. But for most, vision loss is a frustrating experience for many as it dramatically changes their way of life.

Age may also play a part in vision loss, usually changes become apparent after 40 years of age.

Blue wavelengths have an important role in our lives. They manage circadian rhythms and boost mood. However, most of us also experience blue light from digital devices, which emit a blue wavelength range of 400-490 nm — a wavelength that the human eye is unable to block or reflect.
