Decongestant eye drops will scale back redness within the eye, but when used frequently they will enhance redness within the long-run, Goldstein says. You shouldn’t use these for greater than 72 hours at a time.
Different allergy medicines — like oral antihistamines and steroid nasal sprays — can scale back allergy signs total, together with eye allergy signs, however they have to be taken constantly.
When to see a health care provider

It doesn’t matter what sort of allergy eye drops you’re utilizing, attain out to your physician if you happen to abruptly begin having elevated signs.
