How Often Should Adults Have an Eye Exam?

Eye exams are one of those check-ups that feel optional until something goes wrong. Vision changes gradually enough that many people don’t notice the shift, and several serious eye conditions — including glaucoma and diabetic retinopathy — cause no symptoms until they’ve already done significant damage. That’s the case for routine screening: catching problems before they become irreversible.

How often you need an eye exam depends on your age, your risk profile, and where you live. The international picture is less consistent than it is for other preventive checks, in part because one of the world’s major guideline bodies — the US Preventive Services Task Force — takes a notably cautious position that most other countries don’t share.

What routine eye exams are looking for

A comprehensive adult eye exam does more than check whether you need glasses. For screening purposes, the key conditions are:

Glaucoma — Increased pressure inside the eye that damages the optic nerve over time. Often called “the silent thief of sight” because peripheral vision loss occurs gradually and is rarely noticed until advanced. Glaucoma is the leading cause of irreversible blindness globally.

Age-related macular degeneration (AMD) — Deterioration of the central area of the retina, affecting the sharp central vision used for reading and recognising faces. More common in adults over 60.

Diabetic retinopathy — Damage to retinal blood vessels caused by high blood sugar. One of the most common complications of diabetes and a leading cause of blindness in working-age adults. Entirely preventable with early detection and good glucose control.

Cataracts — Clouding of the lens, increasingly common with age. Detectable at eye exam long before they significantly impair vision.

For most of these conditions, by the time symptoms appear, some damage has already occurred. Regular screening is how they get caught early.

Who needs more frequent eye exams

Standard population intervals apply to adults with no significant risk factors. More frequent exams are warranted if any of the following apply:

• Diabetes — Both type 1 and type 2. Diabetic retinopathy risk is closely tied to blood sugar control and duration of diabetes. Most guidelines recommend annual retinal checks for people with diabetes.
• Family history of glaucoma — First-degree relative with glaucoma significantly raises lifetime risk. Many guidelines recommend starting annual checks from age 40 in this group.
• High myopia (short-sightedness) — Highly myopic eyes have structural features that increase glaucoma and retinal detachment risk.
• Previous eye surgery or injury — Prior conditions affecting the eye’s structure warrant closer monitoring.
• Certain medications — Some drugs (including hydroxychloroquine, used for lupus and rheumatoid arthritis) can cause retinal toxicity with long-term use, requiring regular retinal monitoring.
• Age 65 and over — Risk of AMD, glaucoma, and cataracts rises significantly with age, and most guidelines recommend more frequent exams in this group regardless of other risk factors.

Why guidelines differ — and why the US is split

The eye exam landscape is unusual in that the US has two major bodies giving almost opposite advice. Understanding why helps make sense of the broader international variation.

The AAO vs. USPSTF split. The American Academy of Ophthalmology recommends baseline eye disease screening at 40 for all adults, with frequency increasing with age and risk. The US Preventive Services Task Force — which sets guidelines used by primary care physicians — has found insufficient evidence to recommend routine vision screening for asymptomatic adults. These aren’t quite measuring the same thing: the AAO is writing for ophthalmologists conducting comprehensive exams; the USPSTF is assessing whether primary care clinicians should be proactively screening. But the apparent contradiction causes real confusion for patients.

Population programmes vs. individual clinical judgement. The UK and Australia operate on the principle that regular eye tests are valuable for adults of all ages, and fund them accordingly. NHS sight tests are free for people 60 and over, those with glaucoma or at risk of it, and people with diabetes. Australia’s Medicare covers annual tests for those 65 and over. Canada’s CTFPHC, by contrast, found that evidence for primary care-based vision screening in older adults was too weak to support a routine recommendation — a position similar to the USPSTF’s, and similarly contested by optometrists.

What’s being screened matters. Vision acuity screening (can you read the bottom line?) and comprehensive eye disease screening (do you have early glaucoma?) are different things. Some of the evidence disagreement stems from studies that mixed these together. Optometric professional bodies in most countries recommend comprehensive exams; population health bodies are more cautious because the evidence base for meaningful outcomes from mass screening is less robust than for, say, bowel or breast cancer screening.

The practical upshot is consistent regardless of country: if you have diabetes, a family history of glaucoma, or symptoms, the argument for regular eye exams is clear. The debate is mostly about how aggressively asymptomatic, low-risk adults in their 40s and 50s should be pursued for routine checks.

Eye exams and diabetes

Diabetic retinopathy deserves separate mention because the evidence here is much stronger than for general vision screening. Structured retinal screening programmes for people with diabetes exist in the UK, Australia, and parts of Canada, with recall intervals based on individual retinopathy status rather than fixed population intervals.

In the UK, people with diabetes are offered annual digital retinal photography through a dedicated NHS diabetic eye screening programme — separate from routine optician visits. In Australia, diabetes-related eye checks are covered by Medicare and guided by Diabetes Australia recommendations. In the US, the American Diabetes Association recommends annual dilated eye exams for adults with type 1 diabetes (starting five years after diagnosis) and at diagnosis for type 2, with follow-up intervals individualised based on findings.

If you have diabetes and haven’t had a retinal check recently, that’s the one part of this picture where the evidence most clearly supports acting.

Fitting eye exams into a broader check-up routine

Eye exams sit alongside several other checks that become more relevant from age 40 onwards — including blood pressure and cholesterol and blood glucose, both of which affect eye health directly. Diabetic retinopathy is a vascular complication; hypertension also causes retinal changes that an eye exam can detect.

For a broader picture of which checks matter at each decade of adult life, the adults’ health screening guide covers the full schedule in one place.

Frequently Asked Questions

How often should adults have an eye exam?

For low-risk adults, most guidelines suggest every two to four years between ages 40 and 54, every one to three years between 55 and 64, and every one to two years from age 65. Adults with diabetes, a family history of glaucoma, or high myopia typically need annual exams. In the UK, NHS sight tests are available every two years for most adults, and more frequently for those at higher risk.

At what age should I start getting regular eye exams?

The American Academy of Ophthalmology recommends a baseline eye disease screening at age 40, even with no symptoms. Australia similarly recommends starting routine checks at 40. The UK has no fixed starting age — NHS sight tests are available at any age, and how often you're advised to attend depends on your optician's assessment. If you have diabetes or a family history of glaucoma, most guidelines recommend starting earlier, regardless of country.

Does having diabetes mean I need more frequent eye exams?

Yes. Diabetic retinopathy is one of the most common complications of both type 1 and type 2 diabetes, and it causes no symptoms in its early stages. Most guidelines recommend annual retinal checks for people with diabetes. In the UK, the NHS runs a dedicated diabetic eye screening programme separate from routine optician visits. In Australia and the US, similar annual checks are recommended, with intervals potentially extended if several consecutive results are normal.

Why does the USPSTF say there's insufficient evidence for eye screening?

The US Preventive Services Task Force evaluates whether primary care clinicians should proactively screen asymptomatic patients. For vision and glaucoma screening, it found that the evidence linking primary-care-based screening to meaningful reductions in blindness or vision loss was too limited to make a positive recommendation. This doesn't mean eye exams aren't valuable — it means the USPSTF couldn't establish strong enough evidence for population-wide primary care screening. The American Academy of Ophthalmology, writing for specialist eye care clinicians, reaches a different conclusion.

Can I just go to an optician, or do I need a GP referral?

In most countries, you can book directly with an optician or optometrist without a GP referral. In the UK, you can self-refer to any registered optician for an NHS sight test if you're eligible for a free test (which includes adults 60 and over, people with glaucoma or at risk of it, and people with diabetes). In Australia, you can self-refer to an optometrist for a Medicare-rebated appointment. In the US and Canada, optometrists are independently accessible — no referral needed. A referral to an ophthalmologist (medical eye specialist) is typically arranged by your optometrist if they find something that needs further investigation.
