Dry Eye & Glaucoma: Fix the Surface, Fix the Tests Persistent dryness and irritation of the eye surface—often called dry eye disease or ocular surface disease—is very common in people with glaucoma (especially those using eye drops). This surface problem can blur vision, make you blink more, and change the way your eyes see light. That in turn can throw off glaucoma tests. For example, a frustrate...
Artificial tears are over-the-counter eye drops designed to supplement or mimic the natural tear film that keeps the eye surface moist and comfortable. They contain lubricants, salts, and sometimes preservatives or thickening agents to add moisture, protect delicate cells, and reduce irritation. Formulations vary from thin watery drops to thicker gels and ointments, and some products are preservative-free for people who use them frequently or have sensitive eyes. People use them for dry eye symptoms caused by aging, screen use, contact lens wear, environmental conditions, medications, or certain medical conditions. Artificial tears relieve burning, grittiness, redness, and blurry vision that can come from an unstable tear film. Choosing the right type and frequency matters: light drops can be used often during the day, while gels or ointments are better for overnight relief but can blur vision temporarily. Long-term, frequent use of preserved drops may cause irritation for some people, so preservative-free options or doctor guidance are recommended if many doses are needed daily. In more severe cases, artificial tears are one part of a larger treatment plan that could include prescription medications, procedures, or lifestyle changes. Using artificial tears before eye exams or procedures can also improve the surface of the eye and help produce more reliable measurements.
