It was a mountaineering accident and largely self inflicted due to arrogance. (I come from a hot country and I have seen more sun than anyone... losing a sunglass will not kill me. let's climb.... kinda arrogance ).
Luckily I knew what was happening and that it was transient; so I didn't panic. But I had to stay in pitch dark environment for a week as I was extremely light sensitive. It sure did teach me the importance of eyes and how disorienting life without it is. I couldn't even pause a audio player on my bed without seeing.
Writing all that makes me want to try densenets on the diabetic retinopathy kaggle contest. Since it is a small(ish) dataset, perhaps we would be better than VGG + finetuning (which is what Google did, albeit with 4x more data)?
