What are retinal capillaries?

Retinal capillaries are tiny blood vessels that help your eyes see clearly.

Imagine your eye is like a busy city, and the retina is like the main street where all the action happens. Capillaries are like the smallest roads in this city, they let the cars (which are red and white blood cells) zoom through to deliver important supplies (like oxygen and sugar) to the buildings (which are your eye's special cells called photoreceptors).

When you look at something, light goes into your eye and hits these photoreceptor buildings. To keep them working well, they need a steady stream of supplies. That’s where the retinal capillaries come in, they’re like tiny highways that make sure every building gets what it needs to stay healthy and active.

If these little roads get clogged or broken (like when you spill juice on your sidewalk), the buildings can't get their supplies, and you might not see as clearly. That’s why taking care of your retinal capillaries is like keeping the traffic flowing in a busy city, it helps you see the world clearly every day!
