The IRIS — Personalized Lighting Solutions for Glare Reduction The human iris regulates the amount of light entering the eye by contracting or dilating to control how much light reaches the pupil. People with lighter-colored irises are generally more sensitive to glare due to lower pigment levels, while those with darker irises experience less glare sensitivity. To address this challenge, we designed The IRIS, a customizable lighting solution that adapts to individual glare sensitivity. The fixture features an adjustable density of bubbles that diffuse light to minimize glare. For individuals with lighter irises, a higher concentration of bubbles is generated, allowing light to ease the users experience, creating a softer and more comfortable illumination. Conversely, those with darker irises require fewer bubbles for optimal lighting. By tailoring the bubble density based on various iris pigmentations, The IRIS offers a personalized lighting experience that enhances comfort and reduces glare.
