There are many different conditions that can affect the eyes, and some are more common than others. Many affect the cornea, which is the clear, domed lens at the front of the eye. The cornea has several purposes. Not only does it protect the pupil and iris, but it also refracts light as it enters the eye, changing the angle so that it passes through the eye and focuses on the retina. The retina receives the light and turns it into messages that are sent to the brain and tell us what we can see. For most people, the cornea is a fairly evenly shaped dome. However, for people with keratoconus, this isn’t the case.

The eye is one of the most complex organs in our bodies, second only to our brains. For a small organ, the eye consists of more than 2,000,000 working parts. It’s also a very important organ. After all, a large part of how we learn is through our eyes, accounting for 80% of what we know.  

You’ve noticed that you’re increasingly squinting just to get a clearer view while you’re walking or while you’re reading on your mobile device. You’ve always had 20/20 vision, but face it: it looks like you now have to visit your eye doctor and get an eye exam! NZ has a lot of eye doctors, in case you’re wondering, so you won’t have a hard time finding one.
