Most people wait until something feels wrong before they call an eye doctor.
In Tucson, that’s a gamble your eyes can’t afford.
Between the relentless UV exposure, the desert-dry air, the allergy seasons, and one of the highest diabetes rates in the state, this city puts a very specific kind of stress on your vision, year-round.
Here’s how to know when it’s time to make the call.
What an Optometrist Does (and Doesn’t Do)
Before anything else, it helps to know what you’re actually getting when you see an optometrist, because there’s a lot of confusion around who does what in eye care.
An optometrist (OD) is your primary care doctor for eyes. They perform:
- Comprehensive eye exams
- Prescribe glasses and contact lenses
- Diagnose and manage conditions like dry eye
- Detect early signs of glaucoma, cataracts, and diabetic eye disease
- And refer you to a specialist when something needs more advanced care
What they don’t do is surgery. That’s where ophthalmologists come in, medical doctors (MDs) who handle surgical and medically complex cases like cataract removal, glaucoma procedures, and retinal treatment.
You Don’t Have to Figure Out Which One You Need
At Catalina Eye Care, you don’t have to guess. Our team includes optometrists, ophthalmologists, and subspecialists under one roof. If your exam turns up something that needs more than a routine visit, you’re already in the right place; no referrals to strangers, no starting over.
The Tucson Factor: Why This City Demands More From Your Eyes
This is where most “when to see an optometrist” articles get it wrong. They hand you a generic checklist that could apply to literally anyone living anywhere in the country. But Tucson isn’t anywhere.
The environment here is actively working on your eyes in ways that most cities simply aren’t. And that changes how often you should be seen, and what we’re watching for.
286 Days of Sun (and What That Really Means)
Tucson is one of the sunniest cities in the United States. That’s great for outdoor living. It’s harder on your eyes.
Prolonged UV exposure is a well-established driver of cataracts, macular degeneration, and pterygium (a non-cancerous growth on the white of the eye) that’s especially common in desert and coastal climates.
Most people know to wear sunscreen. Far fewer realize that UV damages your eyes just as steadily as it damages your skin, often without any warning signs until the damage is done.
Tucson’s Altitude Amplifies the Risk
Tucson sits at roughly 2,400 feet above sea level. UV intensity increases approximately 10% for every 1,000 meters of elevation, according to the World Health Organization. That means our high-desert climate magnifies UV exposure beyond what most people account for, even with sunglasses on.
The Desert Dryness Isn’t Just an Inconvenience
Low humidity, especially from late spring through early summer, is one of the primary environmental drivers of dry eye disease. Many patients write off their symptoms, such as gritty eyes, burning, blurry vision that comes and goes, as “just allergies” or “just the weather.” But untreated dry eye can lead to chronic inflammation and corneal damage over time.
According to a 2025 Dry Eye Report from Eyes On Eyecare, dry eye disease affects at least 16 million Americans, with estimates suggesting the true number of undiagnosed cases could be as high as 49 million. In a climate like Tucson’s, those numbers matter locally.
Pima County’s Diabetes Rates Are Above the State Average
Arizona’s adult diabetes rate already sits above the national average, and Pima County trends higher still. That’s significant because diabetic retinopathy is one of the leading causes of vision loss in working-age adults, and it develops silently.
You won’t feel it happening. An annual dilated eye exam is the only way to catch it early enough to protect your vision.
The Outdoor Lifestyle Tucson Is Known For
Hiking Sabino Canyon, cycling the Loop, cheering at a UA game under the stadium lights; the outdoor life here is one of the best things about living in Southern Arizona. It also means more sun exposure, more dust, more dry air, and more physical activity that can be hard on your eyes over time. Your optometrist helps you stay ahead of all of it.
Clear Signs It’s Time to See an Optometrist
Not every eye issue is an emergency. But some things shouldn’t wait. Here’s how to read your own symptoms.

These aren’t emergencies, but they’re not things to push off indefinitely either:
- Your vision has shifted; things that used to be sharp aren’t anymore
- You’re squinting at screens, menus, or road signs more than you used to
- You’re getting headaches that seem tied to reading or extended screen time
- Your eyes feel gritty, burning, or dry most days
- It’s been more than a year since your last comprehensive eye exam
That last one counts more than most people think.
Annual exams aren’t just about updating your glasses prescription. They’re how we catch conditions that have no symptoms in the early stages, glaucoma being the most well-known example. A 2024 study published in JAMA Ophthalmology estimated that 4.22 million Americans currently have glaucoma, and more than half of those cases are undiagnosed.
See Us This Week
These symptoms deserve prompt attention:
- Persistent redness or irritation that hasn’t cleared up on its own
- New sensitivity to light, especially notable given Tucson’s sun
- Difficulty driving at dusk or at night (halos, glare, blurred headlights)
- Excessive tearing, counterintuitive, but a classic dry eye signal
- You have diabetes or high blood pressure and haven’t had a dilated exam in the past year
Call Us Today
These are urgent:
- Sudden blurry or distorted vision
- New floaters, especially accompanied by flashes of light
- Any eye pain, particularly when paired with vision changes
- Loss of vision in any portion of your visual field
Sudden changes need to be seen the same day. At Catalina Eye Care, our optometrists will get you to the right level of care immediately. Our in-house ophthalmologists mean you’re never waiting on a referral when time matters.
Life Stage Triggers: When Your Eye Care Needs to Change
The right frequency for eye exams isn’t one-size-fits-all. It changes as you do.
Under 40
You probably assume you’re not in the target demographic for eye problems. But screen time, contact lens habits, and early dry eye don’t care how old you are. If you haven’t had a comprehensive exam recently, or ever, now is a good time to establish a baseline.
Ages 40 to 55
This is when presbyopia typically begins. You’ll notice it first when you need to hold things farther away to read them.
It’s also when early changes related to cataracts, glaucoma, and other age-related conditions can start forming quietly. Annual exams become more important here, not optional.
Ages 55 to 65
Conditions that have been developing silently often begin to surface in this decade. This is not the time to skip a year. This is when catching things early makes the biggest difference in what your vision looks like at 70 and beyond.
Ages 65 and Older
Vision and independence are directly connected. The ability to drive safely, read comfortably, recognize faces all of it depends on your eye health. Glaucoma, macular degeneration, cataracts, and dry eye all require active monitoring at this stage. Annual exams aren’t negotiable.
Diabetic Patients at Any Age
This deserves its own category. If you have diabetes, you need a dilated eye exam every year, full stop.
Diabetic retinopathy doesn’t announce itself. In Tucson and across Pima County, where diabetes rates run above the state average, this is a community-wide conversation we need to be having more often.
What to Expect at Catalina Eye Care
A lot of people put off eye exams because they’re not sure what to expect. Here’s the honest version: it’s easier than you think, and it’s a lot more thorough than most people realize.
It Starts With a Real Conversation
Before we look at anything, we talk. We want to know what’s been bothering you, what your daily life looks like, what your family history is, and what your vision goals are. In Tucson, we also ask about sun exposure, time outdoors, screen habits, and anything allergy- or climate-related because those factors are genuinely relevant here.
A Comprehensive Exam That Goes Beyond 20/20
A full eye exam at Catalina Eye Care includes:
- A visual acuity check
- Refraction (your prescription)
- Intraocular pressure testing for glaucoma
- A slit lamp exam to evaluate the front of the eye
- Retinal imaging to look at the back of the eye
- And a tear film evaluation for dry eye, especially important in our desert climate
We’re not just updating your glasses. We’re looking for signs of glaucoma, cataracts, macular degeneration, diabetic retinopathy, and other conditions that show no symptoms until they’re already causing damage.
The In-House Advantage
If something is found during your exam that requires more than an optometrist can address, you don’t have to start over somewhere else. Catalina Eye Care’s team includes ophthalmologists and subspecialists on site. The transition is seamless, and your records and history come with you.
A Practice That Knows Tucson
Catalina Eye Care is a privately-owned practice, not a corporate chain. That means you’ll see consistent providers who know your history, understand the local environment, and have been caring for Tucson families for years. As one of our patients put it:
“I have highly recommended this office to my family and friends. I wouldn’t do so if I wasn’t completely satisfied with the service my mother and I received.” — Liza C.
Final Thoughts: Your Vision Is Worth Protecting. Tucson Makes It Worth Prioritizing.
Most people think of an eye exam as something you do when something goes wrong. In reality, the whole point is to keep things from going wrong in the first place.
In a city with 286 days of sun, desert-dry air, elevated UV, and higher-than-average rates of diabetes, your eyes are working harder than they would almost anywhere else.
The best thing you can do for your vision is see someone regularly who understands that.
At Catalina Eye Care, that’s exactly what we do.
