Seattle UV Eye Protection: Sunglasses Guide
Sunglasses do more than elevate your style—they’re essential armor against UV damage. At Cannon EyeCare in Seattle, we’ve seen how UV radiation harms eyes in three critical zones: the front (like the pterygium ), the middle layers, and most critically, the retina. Discover why quality sunglasses are non-negotiable for Pacific Northwest residents.
UV damage often begins subtly with pinguecula
—a yellowish thickening of your eye’s conjunctiva (the clear tissue covering the whites). Without protection, this can evolve into:
-
Permanent bumps at 3 or 9 o’clock positions near the cornea
-
Inflammation called pingueculitis
-
Requires prescription drops from a Seattle optometrist
Early intervention at our Capitol Hill clinic prevents progression.
Years of UV exposure—especially in dry, dusty environments—can advance pinguecula to pterygium (shown in photo).
This growth distorts vision by:
-
Causing corneal traction
-
Changing astigmatism prescriptions
-
Creating chronic irritation
Seattle hikers and boaters note: Our marine climate doesn’t eliminate this risk.
While advanced pterygium is less common in lifelong Seattle
residents who wear sunglasses, no Northwesterner is immune. At Cannon EyeCare, we treat patients with:
-
Childhoods in sun-intensive regions (Texas/California)
-
Outdoor careers (construction, fishing)
-
Active lifestyles (skiing, sailing Puget Sound)
Pro tip: Overcast Seattle days still deliver 80% UV radiation
When pterygium obstructs vision, surgery becomes necessary
Seattle patients should know:
- Surgery removes abnormal tissue (high success rate)
- New eyeglass/contact lens prescriptions post-recovery
- 20-40% recurrence risk without UV protection
Prevention remains our top recommendation at Cannon EyeCare.
Beyond surface damage, UV penetrates deeper
Middle Layer: Accelerates cataracts
-
Treatable, but ideally later in life
-
UV exposure can trigger surgery decades early
Retina: Most severe consequences (discussed next)
We help Seattle patients delay cataract development through proactive protection.
Consistent sunglass use prevents premature cataracts
Most critically, UV targets the macula—your retina’s center for sharp vision. Many Seattleites know someone affected by Age-Related Macular Degeneration (AMD), the leading cause of senior blindness nationwide.
While AMD deserves dedicated discussion, understand this: It’s America’s #1 cause of legal blindness in seniors.
Prevention starts young—three controllable risk factors:
-
Genetics: Unchangeable, but knowing family history helps. Ask relatives about vision issues before it’s too late.
-
Smoking: Doubles AMD risk. Quitting preserves sight.
-
UV Exposure: Daily UVA/UVB-blocking sunglasses are non-negotiable, especially in reflective environments like Puget Sound.
Protect your vision where you live. Visit Cannon EyeCare near Pike Place Market for prescription sunglasses that defend against Seattle’s unique UV challenges.

Sunglasses block harmful UV rays that can damage your eyes and the delicate skin around them, reducing your risk of cataracts, macular degeneration, and skin cancer
