Today I have been helping with a project funded by Coopervision being conducted by one of my friends comparing the effects of over the counter blepharitis treatment compared to baby shampoo. In particular it is looking at the effects of the scrubs on ocular comfort and staining. This has resulted in me having fluoroscein and lissamine green put into my eyes, leading to me having a fetching shade of green eyeshadow for most of the day.
Still it's a small price to pay to help for driving research forward.
