UV light is not visible, but it is high energy electromagnetic waves. Your brain doesn't process "excess light" because your eyes aren't sensing visible light.

Your brain doesn't process "excess light" because your eyes aren't sensing visible light. They are being exposed to damage by the rest of the light, nonetheless.

The issue you mention does come up if you have a filter that blocks visible light but not UV. Non-UV-blocking sunglasses, for example, could increase the risk of cataracts compared to not wearing sunglasses at all (mainly because of pupil dilation).
