ROUTINE VISION EXAM=
Visual acuity, testing the focusing ability of the eyes, refraction (measurement for glasses), and a general eye health screening.
TESTS PERFORMED DURING A ROUTINE VISION EXAM AT TVC:
- Auto-refraction– an automated starting point used to measure a glasses prescription.
- Lensometry– this measures the power in your current glasses.
- Visual Acuity– reading letters, numbers, or pictures on an acuity chart calibrated for 20 feet (distance vision) and 14-16 inches (near vision).
- General binocular screening– screening tests on the ability of the eyes to focus and track together, peripheral (side) vision, and pupil responses.
- Refraction– this is the measurement of a glasses prescription.
- Tonometry– this is the measurement of intra-ocular pressure (IOP) which screens for glaucoma.
- Slit Lamp Examination– The “slit lamp” is a microscope that allows the doctor to view the eye under high magnification and screen for diseases of the eye.
- Dilated Examination– Dilating drops can be instilled to cause the pupils to stay dilated and to stop the eye from focusing. This allows a wider view in the back of the eyes and a more controlled measurement for glasses.
- Glasses Prescription– Dr. Mayes prescribes glasses for all your needs.
Clear vision = best refraction + healthy eyes + absence of systemic disease that impedes the visual system.
