What Are Preservative-Free Eye Drops?

Preservative-free eye drops are primarily intended for long-term ocular use and include products such as Sturlyn Eye Drops, Hylo Eye Drops, polyvinyl alcohol eye drops, and natural artificial tears—formulations designed to treat dry eye syndrome. These preservative-free preparations cause minimal ocular irritation and are suitable for prolonged use. However, patients must follow their physician’s instructions regarding dosage and frequency of administration. Additionally, maintaining good ocular hygiene and avoiding visual fatigue in daily life is essential.
