Tobias eye drops are mainly used to treat bacterial conjunctivitis with good effect, but the treatment of dry eye and eye fatigue is not obvious. Dry eye syndrome is caused by insufficient tear secretion or excessive evaporation, resulting in abnormalities in any of the three indicators: tear quality, tear mobility, and tear quantity, causing damage to the ocular surface and tear film instability, resulting in eye discomfort and visual dysfunction. Patients often experience foreign body sensation, dryness, and fatigue in the eyes, which can be restored by brief treatment with artificial tears or polyvinyl alcohol sodium vitreous eye drops, without watching TV or computer, and with less cell phone viewing.
