Artificial tears are specially formulated eye drops designed to mimic the composition of natural tears.

What are artificial tears?
Artificial tears are solutions comprised of water, electrolytes and lubricants. These ingredients help support the tear film which consists of three layers: oil, water and mucus layer. They also help maintain the health of the ocular surface. Unlike prescription eye drops, they are available over the counter, making them easily accessible to those in need of quick relief from dry eye symptoms.
Different types of artificial tears
Artificial tears come in various formulations, each designed to address specific aspects of tear film dysfunction. An individual can choose the appropriate product as per their symptoms.
Preservative-free vs preservative-containing
- Preservative-free eye drops: These are ideal for individuals with sensitive eyes or those who use eye drops frequently. Preservatives can cause irritation if used repeatedly.

Viscosity levels
- Low-viscosity drops: These eye drops have a light, tear-like consistency and spread easily over the eye surface. They provide quick relief but may need more frequent applications.
- High-viscosity drops: Offering long-lasting relief, these eye drops can be thicker and may slightly blur vision temporarily after application.
Specialised formulations
Some eye drops are designed with specific ingredients to target particular symptoms:
- Lipid-based drops: These eye drops are designed for people with meibomian gland dysfunction (MGD), a condition affecting the oil layer of the tear film leading to tears evaporating too quickly. They help restore the lipid layer and reduce tear evaporation.
- Electrolyte-enhanced drops: These eye drops contain important minerals that help keep the eye’s surface healthy and properly balanced.
Eye gels and ointments
Eye gels and ointments are thicker formulations often designed for overnight use. They provide prolonged lubrication, making them ideal for severe dry eye symptoms. Their thicker consistency may cause temporary blurring, but the benefits extend through the night.
