Sucks about the SSI.
Ah, who needs to eat, or to see?
Until you can get some sunglasses, you should look into a hat that'll shade your eyes from the light to cut down on damage.
You should be able to get a hat with a wide enough brim around it to shield your eyes, and it shouldn't be much more than $10-$15 if you can look for stuff on sale.
I'm guilty of not putting mine on if I'm just popping in under the light to adjust something or check on a plant, but that "pop in" always takes 10 times the amount of time as anticipated, and I end up coming out of the grow box with hazy eyes for a few minutes, knowing that the damage is cumulative.
Got to wear sunglasses whenever the grow box opens up...
