Ever noticed someone’s pupils looking unusually tiny? This condition is known as miosis — when the dark center of the eye becomes abnormally small. While it might look harmless, it can actually reveal important clues about your eye health and overall wellbeing.

Miosis can occur for many reasons: bright light, certain medications, health conditions, or even neurological issues. Sometimes, people refer to it as pinpoint pupils because the pupil shrinks to a very tiny dot. In other cases, it may simply be called constricted pupils, especially when it happens in both eyes.

What matters most is why it’s happening. – Is it light-related? – A side effect of medication? – A sign of an underlying condition?

Understanding the cause can prevent long-term complications and help you decide when it’s time to seek medical attention.

If you’ve noticed changes in your own pupil size or someone else’s, don’t ignore it. Subtle signs like miosis can be your eyes trying to tell you something important.
