An eye exam is more than just reading letters on a chart. It’s a straightforward visit that helps ensure your vision stays clear and your eyes remain healthy. Knowing what to expect can make the process easier and give you confidence when scheduling your next appointment.

Why is an Eye Exam Important?

Eye exams play a crucial role in protecting vision and overall health. Many conditions, such as glaucoma or macular degeneration, begin without symptoms, and early detection is key to effective treatment. A routine exam does more than update your prescription—it lets the doctor evaluate the internal structures of your eyes, which may also reveal signs of systemic issues like high blood pressure or diabetes. By scheduling regular checkups, you can preserve clear vision, prevent complications, and gain peace of mind knowing your eyes are healthy.

How often should I get an eye exam?

The frequency of eye exams depends on age, health, and vision needs.

Children should have their first exam between 6 and 12 months, then every one to two years. Adults under 40 usually need an exam every two years, while those aged 40 to 64 are advised to schedule one every one to two years as eye disease risks increase. Adults 65 and older should have yearly exams, and people with higher risks—such as diabetes, high blood pressure, or a family history of eye disease—may need them more often.

How to Prepare for an Eye Exam

Preparation helps the exam run smoothly and ensures accurate results. Before your appointment:

  • Bring current glasses or contact lenses
  • Prepare a list of medications you are taking
  • Note any vision changes, discomfort, or symptoms you’ve experienced
  • Gather relevant medical or family history information
  • Consider writing down questions for your eye doctor

What Happens During an Eye Exam?

A standard eye exam usually lasts 30–60 minutes and covers both vision clarity and overall eye health. The process typically includes:

  • Medical and vision history: The doctor asks about symptoms, family history, medications, and daily visual needs.
  • Visual acuity test: Reading letters on an eye chart to measure how clearly you see at different distances.
  • Refraction test: Using a phoropter to determine the correct glasses or contact lens prescription.
  • Eye muscle and pupil response tests: Checking how the eyes move together and how pupils react to light.
  • Slit-lamp examination: A microscope with bright light is used to examine the cornea, iris, lens, and other front structures of the eye.
  • Retinal evaluation: Often with dilating drops, the doctor checks the retina and optic nerve for conditions like macular degeneration or diabetic changes.

Some patients may also have additional tests—such as peripheral vision, color vision, or retinal imaging—if risk factors or symptoms suggest the need. Afterward, the doctor explains the results, updates prescriptions, and recommends any next steps.

After the Eye Exam

Once the exam is complete, your eye doctor will review the findings with you, explain any changes in your vision, and discuss whether new glasses or contact lenses are needed. If a health concern is detected, you may be advised on treatment options, lifestyle adjustments, or referred for further care. 

In many cases, you’ll also receive guidance on how to reduce eye strain, protect against UV light, or manage screen time more effectively. Leaving the exam, you’ll not only have clarity about your vision but also a clear plan for maintaining healthy eyes in the years ahead. Don’t wait—schedule your eye exam today and take the first step toward clearer vision and healthier eyes!
