Polarized Visual Stimulation

Author: Frank Ross

Fly-casting for trout presents a myriad of challenges, not the least of which is precise presentation. In order to be consistently successful, that precision placement must be in front of a susceptible trout.

Therein lies the rub. Trout live in streams that flow in rhythmic patterns, around rocks, fallen timber and other natural hiding spots. The nature of rippling water under strong sunlight produces numerous refractions of light that can make seeing lurking trout very difficult, if not impossible. It makes you marvel at the old timers that consistently caught fish, without the ability to see below the surface glare that acts as a barrier protecting trout from prying eyes and probing flies.

One of the marvelous things about living at this point in time is the access we have to some very impressive technological advances. You are reading this page, displayed in its wide array of colors, thanks to someone’s concept of electronic signals and silicon -yep, silicon is basically sand.

We now have the ability to cut through the glare caused by reflections on the water, through the marvel of polarization. The concept is very simple, but what a difference it makes, both in improved vision, and less eye strain -not to mention the long term benefits of protection from dangerous ultraviolet rays.

Thirty years ago, a violet was a flower or sometimes a waitress at the truck stop, where you stopped for coffee on your way to the river. Now we’ve found out that it’s a ray of light that can cause eye damage.

Our modern version of the white knight is a chemist in a lab coat, swirling various compounds in test tubes. Complicated chemicals and processes have created products with hard to pronounce names like Barium Floride, Rubidium Iodide and Thallium Bromo-Iodide that have been developed for use with lenses to filter out these harmful rays. The good news is that you don’t have to be a chemist to find the right pair of sunglasses.

If you stick with a quality company, all you have to do is find a pair that has the features and style that you like at a price that fits your budget. While you’re stylin’ in the mirror, you may tend to pay more attention to how they look on you, than how they are to look through. Here are some things to consider before you decide based on cosmetics alone.

There are some subtle differences worth noting, that have more than a subtle impact on your eyes after a long day in the sun. The two major categories are glass or plastic, and then you have the important issue of color. With fishing glasses, color is not about color coordinating your outfit.

Plastic lenses are offered in more exotic shapes and styles. Generally, plastic is more easily scratched but has the advantage of greater impact resistance and lighter weight. Quality plastic lenses, such as those made by Bolle´ and Costa Del Mar, are offered in a wide variety of color and frame styles. Multiple layered plastic lenses are now the industry standard for quality and versatility.

Many glass lenses are made in mass, and then a machine, or person takes two lenses out of a barrel, snaps them in and they’re good to go. Better quality glasses have lenses that are ground to match, and are distortion free. Matched lenses are an important issue when it comes to reducing eyestrain and fatigue.

When you narrow your selection down to brand and frame, then you need to consider the color of your lenses. If you want to have optimal effectiveness under all conditions, you might want to consider having a couple of different colors. What’s the big deal about color?

Colors of the spectrum are passed or absorbed differently by different colors. The human eye has limitations when it comes to processing colors. It can only focus on a narrow spectrum of light at one time. Lighter colors in the middle of the visible light spectrum are the easiest for the eye to focus on. Darker colors add contrast to the field of vision. Blue light falls in the middle of the spectrum and focuses imperfectly on the retina while scattering in the eye. This phenomenon called "blue blur" is further intensified by the presence of moisture and dust particles on clear days, or when haze, fog, rain or snow are present on overcast days.

The effects of color lenses
Neutral GRAY provides contrast and minimizes color distortion. Gray lenses are ideal for all water sports, and most daily outdoor activities. Lenses with a brown, or AMBER increases contrast in most lighting conditions. Amber offers excellent light management properties on bright sunny days as well as cloudy or rainy days. This color is designed for general purpose, high contrast, light situations. VERMILLION, a rose copper tint, heightens visual acuity and enhances color. It delivers the brightest field of vision and is ideal for sight fishing. Costa Del Mar’s SUNRISE color is a high contrast specialty lens designed for early morning and late evening. BLUE is most effective for bright sun conditions. GREEN offers enhanced visual acuity for specific lighting situations such as sight fishing, but green lenses are worn by many for everyday use.
OPTX 20-20
If you wear glasses to tie knots or see things like trees and rocks, you need to consider a good pair of Fitovers. If you don’t need glasses for walking around, adding lenses to your own sunglasses is a good option to consider. For strictly close work, like tying flies or getting your hook out of your buddies’ shirt, OPTX 20-20 offers a unique concept. These soft pliable plastic lenses cling to your glasses through molecular action. These handy, add-on lens let you use your favorite sunglasses while eliminating the need for that extra pair of specs that either dangle around your neck or fall out of your pocket. They come in three magnifications of +2.00D, +2.50D, +3.00D.

Sure catching fish is fun, but nothing compares to seeing your quarry lying in wait, making a perfect presentation, and seeing it rise to the fly. You can only do this with a good pair of polarizing glasses. Without them, you’re just groping around for a pig in a poke.
