Point Out Administration Instructions for Lubricant Eye Gels on Product Labeling
Winter weather will bring questions about how to manage dry eyes.
Lubricant drops (GenTeal, TheraTears, etc) or "artificial tears" are a good starting point. They often work well to moisten the eyes...and are available without a prescription.
Product selection often boils down to cost and patient preference. It can take some trial and error to find one the patient likes.
