Exactly Why Do We See Better When We Squint?

Have you ever found yourself trying to fill out forms at your doctor’s office, or read a product label in the grocery store (or a thousand other scenarios), but realize you’ve forgotten your reading glasses? Often, our instinct is to squint. It seems strange, but surprisingly it can actually help. O.K., it’s not a good long-term strategy, but in a pinch, squinting can improve blurry near vision known as presbyopia.


Have you ever wondered why? How does this work exactly? It’s called the pinhole effect. We are helping our eyes to block unfocused light – similar to looking through a pinhole.


Take a look at this short three-minute video by Minute Physics for a great explanation on how our eyes work like pinholes:




Of course, walking around looking through a tiny hole made by your fingers isn’t a permanent solution to near vision loss. In fact, once we reach our 40s and 50s, most of us begin to struggle with the natural loss of near vision. We start to become dependent on reading glasses or contact lenses to see up close. This is a condition called presbyopia. And it can be very frustrating.


Enter the KAMRA® inlay. Smaller and thinner than a contact lens, the KAMRA inlay is a mini-ring with an opening – or pinhole – that sits in the first few layers of the eye known as the cornea. It provides a natural range of vision – from near to far – and frees you from the constant frustrations of reading glasses or contact lenses. It even offers long-term performance so that you can continue to enjoy clear near vision over time, even as presbyopia progresses.
