Frequently Asked Questions
Does living in Arizona accelerate cataract formation?
Research consistently links cumulative UV exposure to earlier cataract development, and Arizona delivers more annual UV than nearly any other state. Ophthalmologists here recommend UV-blocking sunglasses with wraparound coverage starting in childhood. If you have spent decades in Arizona without consistent eye protection, earlier screening, beginning at age 40, is worth discussing with your eye doctor.
Why is dry eye so common in Arizona?
Low humidity, persistent wind, airborne desert dust, and extended air conditioning use all destabilize the tear film. Arizona ophthalmologists frequently diagnose evaporative dry eye, where tears evaporate too quickly rather than being underproduced. Treatment ranges from preservative-free artificial tears and punctal plugs to newer options like intense pulsed light therapy for meibomian gland dysfunction.
Is UV exposure worse at higher elevations in northern Arizona?
Yes. UV intensity increases roughly 6 to 8% per 1,000 feet of elevation gain. Flagstaff sits at about 7,000 feet, meaning residents and visitors there face meaningfully stronger UV than the Phoenix valley floor. Ophthalmologists serving northern Arizona see higher rates of pterygium and photokeratitis, both directly linked to UV overexposure. Polarized, UV-400 rated lenses are essential year-round at elevation.
