Eye Function
Eye function includes the ability to discern colors (colorblindness), binocular vision, and depth perception. Optometrists use a variety of eye tests to evaluate the function of your eyes during an eye exam.
Phoropter
A device used by optometrists during eye exams to shine a light into the eyes through a series of lenses to determine the prescription necessary for a patient’s prescription lenses.
Refractive Test
An examination of the eye using a phoropter to determine if a patient requires a prescriptive lens correction.
Slit Lamp Exam
When the eyes are viewed under a slit lamp to magnify the internal and external structures of the eye and reveal any abnormalities.
Tonometry
This test uses a tonometer to measure the pressure inside your eye to detect early signs of Glaucoma.
Visual Acuity Test
A visual acuity test determines your eyes’ ability to discern shapes and details from a distance.
