Prescription Sunglasses
Prescription Sunglasses in Phoenix
Phoenix has one of the highest ultraviolet burdens of any major city in the country, and residents accumulate more lifetime exposure than almost anyone. It shows in our exam room as earlier cataract, more pterygium, and more sun-related surface changes than a practice in a cloudier climate would see.
Ultraviolet damage to the eye is cumulative and it does not repair. Every unprotected hour adds to the total. That is the entire argument for treating sunglasses as protective equipment here rather than as a summer purchase.
The second argument is simply comfort. Squinting through desert glare for an hour is exhausting, and it makes driving genuinely harder.
What UV actually does to the eye
- Cataract: ultraviolet exposure is an established risk factor, and cataracts form measurably earlier in high-UV regions
- Pterygium: a growth of tissue across the cornea, strongly associated with sun and wind exposure, and common enough here that it has been called surfer's eye elsewhere and is just as much a desert condition
- Macular degeneration: cumulative UV is among the contributing risk factors
- Photokeratitis: essentially sunburn of the cornea, painful and possible after intense short exposure
- Eyelid skin cancers: the eyelids are thin-skinned, high-exposure and frequently missed by sunscreen
Polarisation, and why it is not the same as UV protection
These get conflated constantly. UV protection is a filter blocking invisible ultraviolet radiation, and it is invisible to you. A completely clear lens can have full UV protection, and a very dark lens can have none.
Polarisation is different. It blocks light waves oriented horizontally, which is what reflected glare off a road surface, a windscreen, water or pale rock consists of. Removing it produces a dramatic improvement in contrast and comfort that people notice immediately when they first try a polarised lens.
In the desert this is not a marginal benefit. Road glare, reflected light off caliche and light-coloured stone, and windscreen reflection are constant, and polarisation removes most of it.
Choosing a tint
- Grey
- Neutral. Reduces brightness without changing colour relationships. The safest all-purpose choice and the best for driving, since traffic signal colours stay true.
- Brown and amber
- Enhances contrast and depth perception by filtering more blue. Excellent for golf, driving in variable light, and any activity where judging distance and terrain matters.
- Green
- Good balance of contrast enhancement and colour fidelity. A comfortable general-purpose alternative to grey.
- Rose and red
- High contrast in flat or low light. Popular for cycling and some snow sports, less suitable as an everyday lens.
- Photochromic
- Darkens outdoors and clears indoors. Convenient as a single-pair solution, with two real caveats: most types darken poorly inside a car because windscreens block the UV that triggers them, and the transition takes time.
Our sunglass brands
We carry Maui Jim, Oakley and Ray-Ban in prescription. Each has a genuine strength rather than being interchangeable.
Maui Jim's PolarizedPlus2 is the best desert lens we stock. Colour rendering is noticeably better than most polarised lenses, which usually flatten colour, and glare control is excellent. If you spend real time outdoors here, it is worth the premium.
Oakley is the performance choice, with wrap geometry and grip that stay put during activity. Wrapped frames need lens compensation to correct the optics for the curvature, which we handle as part of the fitting. Ray-Ban carries the classic shapes in prescription for anyone who wants an everyday pair that looks like nothing else.
Children need this more than adults do
This is the part most parents have not been told. A significant proportion of a person's lifetime ultraviolet exposure occurs before age eighteen, and a child's crystalline lens is clearer than an adult's, so it filters less and allows more UV to reach the retina.
Children also spend far more time outdoors than adults here. Protective sunglasses for children are genuinely preventive, and they cost very little relative to the exposure they remove.
Who this is for
- Everyone who lives in Arizona and spends time outdoors, which is essentially everyone
- Drivers who struggle with road and windscreen glare
- Golfers, hikers, cyclists and runners
- Anyone who has had cataract surgery, where UV protection matters more afterward
- Patients with macular degeneration or a family history of it
- Children, who accumulate a large share of lifetime exposure before adulthood
Our process
Every patient goes through the same sequence, so you always know what happens next.
- 1
Discuss where you will wear them
Driving, golf, water, general wear. This decides tint and polarisation more than anything else.
- 2
Frame selection
Coverage matters. Wrapped and larger frames block peripheral light that reaches the eye around a smaller frame.
- 3
Lens and tint specification
Material, tint, polarisation and full UV protection specified together.
- 4
Wrap compensation where needed
Curved frames require optical compensation so the prescription is accurate through the curvature.
- 5
Precise measurements
Taken in the chosen frame, as with any prescription eyewear.
- 6
Fitting and adjustment
Adjusted so they stay put during activity, and readjusted free whenever needed.

Prescription Sunglasses questions, answered
Are polarised lenses worth the extra cost?
In Arizona, yes, and it is one of the clearest value upgrades in optics. The reduction in reflected glare off roads and pale desert surfaces is immediately obvious. The one exception is if you frequently need to read an LCD screen outdoors, since polarisation can make some displays hard to see at certain angles.
Do darker lenses protect better?
No, and this is an important misconception. Tint darkness and UV protection are unrelated. A dark lens without UV protection is actively worse than no sunglasses, because the darkness dilates your pupil and lets more unfiltered UV reach the retina. Always confirm full UV protection.
Can I get progressives in sunglasses?
Yes, and for presbyopic patients it is worth doing. Progressive sunglasses let you read a scorecard, a menu or a phone outdoors without changing glasses.
Are photochromic lenses a good substitute for a second pair?
They are convenient and a reasonable compromise for many people. Two limitations: most darken poorly in a car because windscreens block the triggering UV, and they do not reach the darkness of a dedicated sunglass lens. For serious outdoor time in Arizona, a dedicated pair is better.
Does insurance cover prescription sunglasses?
Some vision plans allow the frame or lens allowance to be applied to sunglasses instead of clear glasses, and some cover a second pair. It varies considerably. We check your specific benefit and tell you what applies.
