I usually keep acids away from my eye area...except for DMAE, which is acidic but has firming properties. The eye area doesn't need any exfoliation, so I don't use anything exfoliating there, like AHA or BHA acids or micro-dermabrasion crystals or cloths or anything else. Retin-A isn't an acid, and it's proved to reduce fine lines, so of course that goes in my eye area. Moisturizers should be used with caution in the eye area too...too heavy of a moisturizer can cause those little bumps, called milia. A light moisturizer (like my favorite emu) is fine though.
