We take many of our body’s daily functions for granted, like using our legs to move, our voice to talk, or our eyes to see. Sight helps us navigate the world around us; our eyes communicate with our brain about the size, shape, color, and texture of things. As we age, we are more vulnerable to diseases that impair our vision, like cataracts, but they’re treatable, and most importantly, preventable.
In Brit Lab’s latest video, “What Are Cataracts?” host Greg Foot explains cataracts appear in the lens of the eyes, the clear, crystalline structure that sits just behind the pupil. The cataract causes the lens to become less transparent, giving us misty or blurred vision. The lenses are made of a precise structure of water and proteins, which start to clump together as we get older. This blocks some light from entering the eye, and also reduces the sharpness of the images we see.
