Ophthalmic equipment covers a wide range of tools, starting from simple handheld instruments to highly advanced diagnostic machines. These instruments are essential in identifying, measuring, and treating different eye disorders. Examples include the trial lens set and frame, which help assess vision correction; vision testing equipment used for evaluating eyesight clarity; auto-refractometers that automatically measure refractive errors; and keratometers, which determine the curvature of the cornea for accurate diagnosis and treatment planning.
