Selecting Sunglasses for Boating & Fishing!

Boating Fishing sunglasses eyeglasses Honolulu Hawaii Waikiki Oahu
Protection from bright light and UV radiation is very important when you are spending time on the ocean

Sunglasses protect the eyes from the sun's damaging UV radiation, and improve visibility and comfort on the water by reducing light intensity and filtering out glare. On the water, the combination of direct and reflected light is much brighter than on land. Unfiltered glare, the light reflected off flat surfaces like water, windshields, bright white decks and sails, is so intense that it impairs vision (a clear safety hazard). Glare causes squinting, fatigues the eyes, and can result in visual discomfort and headaches. Glare is present even on hazy days. Most sunglasses reduce light intensity by 80-90 percent with darkening gray, green, amber, or other colored lens.

Polarized lenses

Colored lenses alone are not enough protection for marine conditions. To filter out intense glare and prevent squinting, sunglasses for boating should be polarized. And they should be coated to block 99-100 percent of the damaging UVA and UVB (ultraviolet) rays that can reduce visual acuity at night, and cause degenerative eye diseases like photokeratitis, snow blindness, cataracts, pterygium, and various forms of eye cancer. Sunglasses should also be shatterproof to protect the eyes from injury in the event of sudden impact.

When light rays reflect off a surface, the reflected rays concentrate in one plane and are said to be polarized. Reflected glare is an example of polarized light. Even on overcast days, the high–intensity light we call glare can be harsh and overwhelming to your eyes. It blinds you and masks what's behind it. Squinting blocks out some of the light, but not the glare. Ordinary sunglasses can reduce the total amount of light reaching your eyes but, like squinting, they don't eliminate the glare. A polarized lens filters out the glare by blocking all polarized light waves except those traveling in a specific orientation.

A polarized lens blocks horizontally polarized light with a polarizing film of molecules running in parallel vertical chains sandwiched between two optical lenses. These vertical chains block horizontal light waves, allowing only vertical light waves to pass through. Vertical light waves, commonly called "ambient light," are scattered evenly and don't produce glare. You can tell if a lens is polarized by rotating the glasses (or tilting your head when you are wearing them). You will find that they reduce glare better in some positions than others.

By blocking out only the polarized glare, the intensity of the light reaching your eyes is not reduced, so objects retain their definition and visual detail. This effect, combined with a tinted lens, makes it much easier to see and identify things both on and below the water like fish, buoys, skiers, wind zephyrs and underwater hazards.

Some manufacturers use polarized lenses to reduce glare on LCD instruments, fishfinders, etc. When viewed through sunglasses that are polarized differently than the instrument lens, no light is transmitted and the instrument face appears black. The only solution is to remove the glasses.

Getting a good fit

Sunglasses should fit the wearer's face, not only to look good, but so the optical center of the lenses roughly matches the wearer's center of focus to minimize distortion. The three basic measurements for sunglasses are lens size, temple length, and overall width. Glasses should fit snugly without pinching. Weight can also be a factor in correct fit; glasses that are too heavy on the nose can cause headaches.

Lens shape

Optically speaking, the flatter the lens, the less distortion. Curved lenses refract, or bend, the light rays as they pass through, so light doesn't enter your eye in a straight line. Your eyes are forced to work overtime to process and correct the visual information, which may cause eye fatigue and headaches. This distortion can be eliminated with corrected prismatics; check the label for distortion-free prismatics before purchasing curved sunglasses. Lenses of good sunglasses are complex, and are constructed from several layers. The inside has an antireflective coating to reduce "bounce-back" on the inside of the lens and a water-repellant coating to shed water and make cleaning easy. An ultraviolet coating protects your eyes from UVA and UVB radiation.

Lens material

Lenses made of polycarbonate are extremely tough, yet lighter than glass, and can be made oversized to wrap around the face and block entry of light, wind and dirt from the sides, top and bottom. Polycarbonate lenses are impact-resistant and shatterproof, an important safety feature, especially for sailors, who may be at risk of being struck in the face. They naturally block 100 percent of the sun’s harmful UV rays.

Optically ground glass lenses provide the best quality and vision and are more scratch resistant, but they are also heavier. A "compromise" lens material is CR-39, a plastic polymer with optics superior to polycarbonate, but with similar impact resistance and the best scratch resistance of all plastic lenses.

Frames

The best materials for boating sunglass frames are lightweight, flexible, durable materials such as nylon, propionate or acetate (also called zyl). Metal frames may be stylish, but they will quickly corrode to a ghastly green in a saltwater environment. Some manufacturers, such as Costa, use corrosion-resistant monel in their frames.

Frame hardware is made with either strong, maintenance-free pressed-in pin hinges, or with spring hinges for a snug, comfortable fit. Frame hardware should be corrosion-proof. Most of the sunglasses we sell have corrosion-proof nickel-silver or stainless steel hardware.

Wire core sunglasses have heavy wire embedded in the temples and earpieces for maximum adjustability and shaping to achieve a custom fit.

Lenses can be waterproof coated to shed water and make cleaning easy, or mirror-coated to eliminate overhead and reflected glare at the front of the lens. According to one manufacturer, mirror coating provides more control over the transmission of specific wavelengths than lens color, so it can enhance the visual sharpness and contrast of the lens. Some lenses are also coated on the interior with an anti-reflective coating to reduce "bounce-back" on the inside of the lens.
