Most of us notice our eyes becoming red, itchy, or tired. But if you look closely in the mirror, the shape of our pupils can tell you more than you think. Changes in their size can be harmless, but in some cases, they indicate more serious health problems.
Below is an overview of the most common forms and their possible meanings:
1. Round pupils (normal)
-
The most common and expected form.
-
It responds well to light (shrinks in bright light, expands in the dark).
-
Overall, this indicates proper functioning of the eyes and nervous system.
If your pets look like this, you are probably within the "normal" range.
2. Oval pupils
