AI Systems Don't Recognize People With Darker Skin Tones. That's a Major Problem.

Sight is a miracle-- the relationship of reflection, refraction, and messages decoded by nerves within the brain. When you look at an object, you're staring at a reflection of light that enters your cornea in wavelengths. As it enters the cornea, the light is refracted, or bent, toward the thin, filmy crystalline lens that further refracts the light. The lens is a fine-tuner: it focuses the light more directly at the retina, forming a smaller, more focused beam. At the retina, the light stimulates photoreceptor cells called rods and cones.
