How Often Should You Have an Eye Test?

Most people associate an eye test with getting new prescription glasses or contact lenses. Comprehensive eye exams are more than simply checking your vision, they evaluate your entire ocular health. With most eye conditions developing silently without obvious vision changes or pain, regular eye tests are important, protecting your vision in the long run. So how often should you have an eye test? This answer depends on your age, health risk factors, and whether you already wear prescription glasses or lenses.

The Standard Guidelines by Age

The standard guideline by age is for those with healthy eyes and no obvious symptoms. The following schedule is generally followed:

  • Children under 16 – once a year due to rapid growth and their vision changing quickly
  • Adults 16 to 64 – if you do not have underlying eye conditions, you can have an eye test every two years
  • Adults 65 and over – age-related eye conditions risk increases at this stage of life, which is why you should have an eye exam each year, screening for cataracts, glaucoma, and macular degeneration

When Should You Have More Frequent Eye Tests?

The general baseline is every two years for adults, but there are some risk factors that may result in you having more frequent eye tests at your optometrist. If you meet any of the following, we recommend an annual tests:

  • Your wear prescription glasses or contact lenses
  • You have a medical condition, such as diabetes or high blood pressure that means regular retina monitor is important
  • You have a family history of eye disease, such as glaucoma
  • You can certain prescription medications that can impact your vision over time

Conclusion

Do not wait for a routine reminder that you need an eye test if you notice sudden changes. Any persistent headaches, blurred vision, flashes of light, new floaters, or eye strain should have an eye test immediately. Your eyes don't often give you signs and symptoms until the condition is advanced, which is why regular eye exams are essential in preserving your vision.

Frequently Asked Questions

Cannot find what you are looking for? Our team answers every enquiry personally.

Is every two years often enough for an eye test?

Most healthy adults under the age of sixty without any risk factors can have an eye test every two years. Those with health conditions, such as diabetes, children, and those over sixty, should be seen more frequently. Your optometrist will recommend your eye exam frequency.

Do I need an eye test if my vision seems fine?

Yes, if you are due for an eye test, don't cancel the appointment. Most serious eye conditions have no symptoms until significant damage has taken place. Regular eye exams detect any changes before they negatively impact your sight.

At what age should children have their first eye test?

At EyeSmile, we recommend children have their first eye test at the age of three, before they start school. This helps to ensure your child's vision is excellent for when they need to focus on a blackboard. It also helps us detect lazy eye with ease, treating it in the early stages.
