Periodic eye exams are an important part of preventive health care. Many eye and vision problems have no obvious signs or symptoms, so you might not know a problem exists. Each exam usually includes a workup, refraction and an eye health evaluation.
The workup includes taking a history of any medical issues, medications, work-related or environmental issues that could affect your vision.
the refraction will include taking your visual acuities to assess your current vision. It will also include finding a glasses prescription if needed that will give you the best vision possible.
The eye health evaluation can include; depth perception, color vision, eye muscle movement, peripheral vision, and pressure testing. Additional testing may be used to extensively evaluate certain conditions based on the patients' risk and initial findings.
