Are Opcon-A eyedrops safe for daily use? [19m]

I’m allergic to pollen and despite my current allergy meds (generic Flonase) my eyes get extremely itchy and my nose runs. I can deal with the runny nose but the eye itchyness is unbearable at times. In the past I’ve used opcon-a every day for this but I’ve heard recently that it can cause issues. Is this safe to use daily? And if not what should I use?
