Participants must be comfortable with random assignment to have one of their eyes tested with either a Schocket scleral depressor, Josephberg-Besser scleral depressor, or cotton tip applicator.

What is being tested?

The study aims to compare three tools used in eye exams: Schocket and Josephberg-Besser scleral depressors, and cotton tip applicators. Patients will have different tools used on each eye randomly to determine which causes less discomfort while being effective for the doctor.

What are the potential side effects?

Potential side effects may include discomfort or pain in the eyes during or after using any of these instruments. The severity can vary depending on individual sensitivity and reaction to pressure applied by each tool.
