Anything good for crusty eyes due to my allergies?

Yes. Many options 1. Allergy eye drops - otc or prescription - if otc make sure they are 'antihistamine' drops 2. Wet cool washcloth 3. Eyelid scrubs 4. Sun glasses 5. Shower after being outside 6. Oral antihistamines (i.e. Zyrtec, claritin, (loratadine) allegra) 7. Allergy immunotherapy (i.e. Allergy shots).
Crustiness. Try frequent saline cleansing of the lids with at least 4 times a day saline eye drops plus an oral antihistamine. Next try an allergic eye drop such as alomide. Lastly you may need blephamide ointment as it may be complicated. The latter two are under medical supervision.
