Black blob experiences

[arsenal9]

I have experienced black 'polo shaped' blobs in my right eye, which appear on waking, but disappear within an hour. I also get a triangular blob in my left eye. I only see these blobs on holiday and only after about four days. I think that being exposed to long periods of bright sunlight may cause the problem. The blobs were more pronounced in Denmark, but less so in Scotland. Once home, and being mostly inside, the blobs reduce over a few days and then disappear completely. On holidays I wear a hat, and glasses that darken in bright light, but the blobs still occur, as described above. I hope this helps somebody........
