When you were a child, did you mother admonish you not to read in the dark? Did she tell you to turn a lamp on so you wouldn’t ruin your eyes? You probably didn’t think much of it at the time. That’s because your young eyes didn’t struggle to see even in dim light. Now that you’re getting older, though, Mom’s words might be echoing in your mind. That’s because our eyes start to worsen as we age and we begin to need better light to read by. Don’t worry; this isn’t really because of the squinting that you did as a kid. And it’s a problem that you can easily deal with by selecting the right lighting for reading.
So what happens to your eyes as you age? Quite a few things happen actually. Some of the changes that your eyes go through as you get older include:
* The cornea becomes increasingly opaque.
* The lens of your eye starts to absorb more light than before.
* The lens of your eye begins to yellow and specifically absorbs more blue wavelength light than before.
* The diameter of your pupil decreases.
* Your retinal illuminance levels decrease.
* Fat deposits build up in both the cornea and the lens of the eye. This leads to scattered light in the eyes. Scattered light blurs images.
* Your ciliary muscles weaken and your lens hardens. This combination makes it more difficult to focus in changing light.
