During your comprehensive eye exam the optometrist will thoroughly examine your vision and the health of your eyes. We use an array of different tests to determine both your refractive errors and the condition of your eye. The exam will take around 30 to 60 minutes. At the end of the exam you will be dilated, this is when your pupils are enlarged, with medicated eye drops, allowing the doctor to see the internal structures of the back of your eyes. The optometrist will a flash light into your eyes to look at things like: your optic nerve, the retina, important blood vessels, and the lens as a whole. Looking at the condition of these structures can help the doctor diagnose or treat conditions or diseases such as HIGH BLOOD PRESSURE, DIABETES, EARLY SIGNS OF MACULAR DEGENERATION, RISK OF RETINAL DETACHMENT, CATARACTS, AND EARLY SIGNS OF GLAUCOMA.
