Several tests are performed to evaluate your vision and eye health during an eye exam. These include a visual acuity test to measure how well you see at various distances and a refraction assessment to determine your prescription for glasses or contact lenses. Eye exams also include tests for eye alignment, eye movement, and depth perception. The health of your eyes is assessed through a slit lamp examination to examine the structures of your eye and tonometry to measure eye pressure, which can indicate glaucoma. Additionally, eye exams allow the optometrist to examine the back of your eye, including the retina and optic nerve, for signs of damage or disease. These comprehensive evaluations ensure a thorough understanding of your vision needs and eye health.
