I'm not sure without seeing it, if it's an infection or if it's allergy related. There are a couple of things you could check before bringing him to the vet that could rule out things, one is you could give him a Benadryl and see if he gets any relief from his symptoms, another thing you could do is kind of analyze the eye boogers. Look at the colour, if it's green it's more than likely an infection, as opposed to if its a more clear or yellow discharge, which would be more allergy related, you can also smell the eye discharge ( I know this sounds gross, sorry ), but if it has an odor to it, it's probably an infection. There are two types of over the counter Polysporin eye drops that you can buy at the drugstore, one is for allergy eyes, and one is formulated for infections, it's an over the counter eye drops with antibiotics in it, which can also be used for pink eye. If the eye discharge is green, or smells, treat it as infection with the antibiotic drops, and if the discharge is more clear and runny, treat it as an allergy and try the Polysporin for allergy eyes. Whichever drops you use, take him to the vets if you don't see an improvement, or get results in a couple of days. This will give you something to try over the weekend, and if by Monday his eyes don't look better, or if he still has is charge, take him to the vets to have him checked out. I hope this helps, and I hope Herman feels better soon. Please keep us posted on no he's doing.
