There’s a reason sunglasses are an essential piece of safety gear for fly anglers: Regardless of where or how you fish, there’s always a risk of hooking yourself or a buddy in the eye. Ask any guide, and they will probably have a horror story to tell. When hooks are flying through the air, especially on a windy day, sunglasses should be mandatory for anglers and anyone nearby.
Not only do sunglasses protect your eyes, they can also help you spot fish or their shadows from above. But like any tool, different sunglasses perform better in different situations, particularly water types. Saltwater fishing on the flats and spotting big browns in gin-clear water may both require glare reduction and contrast enhancement, but different lens colors can enhance vision in the distinct water colors when you’re sight fishing. So what’s the difference between a lens better for shallow, turquoise salt water in Florida and one better for deeper tannin-tinted mountain streams? Here are some variables to consider.
The great equalizer for fishing sunglasses is polarization. If nothing else, your sunglasses need to be polarized. Polarization reduces glare caused by light reflecting off the surface of the water. At best, glare is an annoyance, but at worst it can be blinding when clear vision is a must. And though you expect midday glare on open water, early morning and late evening glare on small streams can be just as bad or worse.
Polarized lenses act as mini ‘Venetian blinds,’ aligned in a way that eliminates about three-quarters of the glare. This helps you see fish below the surface of the water, but you can also spot submerged rocks and wood, so wading is easier and safer.
There are two ways to polarize glasses: The first results in a less expensive product and the second produces a higher-quality lens. In the less expensive version, the polarizing film is attached to the outside of the lenses. Unfortunately, the film will eventually peel away from the lens— it’s just not as durable. This method can also result in less effective polarization, as it can be applied off the vertical axis, which is crucial to the performance of the film. Higher-quality, higher-priced glasses have lenses with the polarizing film sandwiched between lens layers, encapsulating it. Placement is aligned exactly for optimum performance and will give you superior clarity, better peripheral vision, and durability.
A lot of sunglasses advertised as polarized actually aren't. Do this simple test before you buy a pair of sunglasses to make sure: Put on the glasses and look at your cell phone. Slowly rotate your phone to a 90-degree angle, and see if the reflective glare diminishes or increases. If the sunglasses are polarized, it should be difficult to read what’s on the screen without rotating the phone.
The most difficult thing about choosing the best sight fishing sunglasses is picking the right lens color, since there’s no clear-cut right or wrong choice. Everybody sees color differently and everyone’s vision responds to lens color differently. Here are some general guidelines.
Choosing the right sunglasses for the water you plan to fish can significantly improve your experience, beyond just the safety. While you can’t go wrong with a pair of polarized amber lenses, it’s worth exploring some of the other lens tints to enhance your vision in more specific water types and light conditions.
