Lenses in our eyes are what enable us to see the world. They are like tiny, clear discs that bend light to focus it on the retina at the back of our eye. This creates a clear image for the brain to process.
The eye’s lenses are incredibly flexible and adapt based on what we are looking at. This is why we can see objects at different distances with clarity. If we are looking at something far away, like a mountain, our lens becomes thinner to help us focus. If we are looking at a book, our lens becomes thicker.
As we age, however, our eye lenses can become less flexible. This is why many people need glasses or contact lenses as they grow older. The lenses become less able to adapt to different distances, resulting in blurry vision.
Another common issue with eye lenses is cataracts. Cataracts occur when the lens becomes cloudy, causing vision to become hazy. Fortunately, cataract surgery can remove the cloudy lens and replace it with an artificial one, restoring a person’s vision.
Eye lenses are truly remarkable and essential to our ability to see. Taking care of our eyes through regular check-ups, protecting them from harmful UV rays, and living a healthy lifestyle can help ensure that our lenses stay healthy and functional.
