|Allergies commonly affect BOTH eyes, not just one.
Labs can have multiple eye issues including entropia where the lower lid curls inward and rubs on the eye and dictasia, possibly spelled wrong, sorry, but this is where extra lashes grow on the INSIDE of the lower lid, again causing irritation by rubbing on the eyeball. There can also be problems with the tear duct causing it to fail to drain correctly. It could also be a corneal scratch or ulcer, again causing redness and excessive tearing.
These are just a few issues which can and do cause the symptoms you describe. Your best bet is to get an appointment with a veterinary opthalmologist for a good eye exam. This should be done sooner rather than later as eye problems can go bad very quickly and lead to blindness.
