With the sextant I am very careful with suitable filters. But Bris gives me a little afraid, because that is my building and I have no certainty of protection.

That I remember I had three eye irritation and inflammations, as conjunctivitis, due to the sun.
Two of them skiing, despite carrying sunglasses with CE certified.
The other happened a long time looking through binoculars at sea.
In a few days the problemed go away.
