On the subject of eyes -
My lovely wife had these little black dots that, with her describing them to our HMO, made them seem insignificant. And the HMO said eventually come in. Then they started getting bigger and blocking a lot of her vision. When we got to the HMO she was diagnosed with wet AMD and they rushed her to appointments for shots.
There are several "levels" of anti-VEGF injections, some are VERY expensive and not all insurance covers the better ones.
But she has been taking monthly shots and now the black spots have become slightly translucent and hopefully will not get worse.
