The topic of polarized fishing sunglasses is surprisingly technical. These anti-glare lenses are not merely darkened. They are specially made to filter out light reflected off water. Understanding how they work means understanding how light operates. Of course, like much other technology, you can just take it on faith and use the glasses because they work.
You can either get a basic understanding of light and how it reflects, as well as how polarizing lenses work, or you can depend on the expertise of the manufacturer. Remember the old adage, 'Buyer beware', however. When it comes to protecting your eyesight, you might want to invest the time and effort to know how and when to use this sort of glare barrier.
This is where it gets both interesting to some and confusing to others. Light in its natural form - sunlight - is 'scattered', meaning that it comes from many different directions. It's when light travels in a direct path, as when it's reflected off water, that it causes what we call glare.
The time of day affects how glare-filtering lenses work, according to experts. Fishing sunglasses work best when the sun is neither too high nor too low. Wearers learn how to hold their heads and direct their glances for best effect, as well. When looking into the water, the angle is important for best sightings of the bottom of the lake, river, or ocean, as well as the best view of fish.
Water reflects light differently than snow does, but it bounces off a car hood in a similar manner to it's action on the water's surface. This is one reason why skiers might not want to use this sort of eye protection. Things far away may appear clearer and light will be blocked in general, but icy patches may not show up, causing a dangerous situation. Drivers may also find vision impaired under certain conditions, as might those trying to read digital instruments.
Actually, the topic of reflected light would make a great science fair project. For those who just want to wear glasses that help them see when on the water, all this information might not be necessary. The fact is that these lenses can both help cut glare off the water and make objects underwater - like fish - more visible. They block out reflections of clouds as well as light, apparently.
The best way to proceed if you don't want an in-depth understanding is to find a reputable manufacturer and depend on their expertise to provide you with the proper gear. Fishing magazines and online sites are good sources of information, as are customer reviews. An eye doctor might be able to give you good advice on this specialized form of eye protection.
If you really want to know what you're doing, the internet has some great sites with charts and other aids to understanding how light works and how it bounces off different surfaces. There's even a test you can do to make sure the glasses you have are truly polarized. Take control of your own health and safety with a better understanding of this important topic.
