Yep, it’s hot outside and that glare is nuclear! Get the right kind of shades to handle it…

It’s 98 degrees in Portland right now—you already know that, but your eyes may need the reminder. This heat isn’t just about sweating through your shirt or wondering if your steering wheel is made of lava; your eyes are taking a beating, too. That squint you’ve been doing all day? Not a good long-term plan. Let’s look at sunglasses that will keep you cool, protect your vision, and perform well in the summer sun.

Why does this matter? Sunlight feels great in moderation, but UV rays don’t care how stylish your shades are. Without proper protection, all that glare bouncing off the Willamette could cause lasting damage to your vision.

UV Protection Is More Than A Lens Sticker

In a best-case scenario, you want shades labeled “UV400,” meaning they block 100% of both UVA and UVB rays up to 400 nanometers — the entire harmful UV spectrum. If you can manage, polarized lenses are an excellent addition because they cut glare from reflective surfaces like water and pavement. UV400 keeps your eyes safe from UV damage, while polarization keeps you from squinting, reducing eye strain and related issues. In contrast, many cheap sunglasses use dark-tinted plastic without real UV protection, which can increase the risk. Remember: UV400 is not an SPF rating; “400” refers to the nanometer wavelength cutoff for UV light.

Choose Frames That Do Not Feel Like Hot Metal

Have you ever left a metal water bottle in the sun? Metal frames can feel the same way on a hot day. Acetate frames, or other lightweight composites, stay cooler, sit more comfortably, and won’t slide around when you start to sweat. Find a pair in carbon fiber and you’ll wonder how you ever managed summer without them.

Fit is everything in this Heat

Silicone nose pads are worth paying attention to, especially adjustable ones. They keep your glasses in place when the humidity rises and help prevent slipping, so you’re not constantly pushing them back up. A proper fit makes a noticeable difference in comfort. Fogged lenses can be just as frustrating. Anti-fog sprays work well, but in a pinch, a drop of dish soap rubbed onto each lens and then wiped off will leave a thin film that helps prevent fog from forming. It’s a simple, quick fix until you can clean them properly.

Style is still important

Functionality doesn’t have to mean plain. Aviators are a classic for a reason—they suit most face shapes, provide solid glare protection, and are comfortable to wear. Chunky frames are another good choice, since they help hide fingerprints and smudges. Gradient lenses offer style while still letting you see clearly when looking down at your phone.

Quick refresher to stay comfortable in the heat: look for UV400 or polarized lenses, choose acetate or other lightweight materials, consider silicone pads for grip, and use anti-fog spray or the dish soap trick when needed. Pick styles that make you feel confident, and keep a backup pair in your car or bag—you’ll be glad you did the day you forget your go-to shades.

Even in a heatwave, Portland has a way of showing off. Protect your eyes, drink plenty of water, and take in the sunshine without the constant squint. Got a favorite sunglasses hack or the perfect spot to put them to the test? We’d love to hear it. Good advice is always better when it’s shared.
