Ultralife

**Ultralife** is an over-the-counter ophthalmic lubricant developed and manufactured by **Grevis Pharma** (Grevis Pharmaceuticals). It is formulated as eye drops containing a combination of **polyethylene glycol** (0.4%) and **propylene glycol** (0.3%). The product is primarily indicated for the temporary relief of burning, irritation, and discomfort associated with dry eye syndrome, environmental factors (such as wind, smoke, or air conditioning), and digital eye strain. Mechanistically, the active ingredients function as humectants and lubricants that mimic natural tears, coating the ocular surface to reduce moisture evaporation and facilitate smooth movement of the eyelids over the cornea.
