Sunglasses 101
Sunglasses are not as simple as many people think. As such, it's
important that you get "briefed" before you buy.
The different parts to sunglasses will have a great impact on
the look and feel of the pair. Different parts can also affect
UV protection, glare resistance, and what sports the sunglasses
would best be used for. With this in mind, it is important to
consider each of the different options available for sunglasses.
Different sunglass lenses, tints, and coatings will be
beneficial depending on the intended use. Lens materials also
serve different purposes. The best lenses to use are glass
lenses, because they are of the highest quality and most scratch
resistant. Unfortunately, the glass lenses are also the most
expensive. Acrylic plastic lenses are the least expensive and
weigh less. As a result, they are not of the highest quality and
therefore scratch extremely easily. For casual ware, less
expensive glasses may be preferred. For sports, higher-quality
lenses should probably be considered.
Sunglass tints also serve different purposes. The common tints
are amber and orange, brown, gray, green, rose, vermilion, and
yellow. Amber and orange tints reduce blue light, which is a
chief component of glare. This tint is ideal for high glare
sports like fishing, boating, skiing, and flying. Brown tints
are good for variable light conditions. The dark tint reduces
eyestrain, making it an ideal tint for driving, cycling, and
running. Gray and green tints are good tints for many purposes.
Rose, vermillion, and yellow are all solid daytime tints.
Certain tints work best for certain needs, but the best way to
find out is to try different tints. If the tint fits your needs,
than it is a good option. There are also several different
coatings for lenses. Some coatings are anti-reflective, while
others have mirrors.
The frame of the glasses is very important. There are several
materials for frames. Plastic frames are the cheapest and
therefore not of as high quality. Plastic frames also crack
easily. Nylon and metal frames are both good choices. However,
nylon is flexible and stronger than metal. The hinge can also
have metal and nylon. Again, in this instance, nylon is stronger
and therefore probably the better choice.
Whichever pair you choose, I'd like to leave you with a bit of
advice: remember you're your lenses should be cleaned often. For
cleaning sunglass lenses, mild soap and warm water should be
used. Cleaning lenses removes dirt and oil and helps avoid
buildup of debris, which can cloud vision or scratch lenses.
After washing lenses, one should dry them with a lens cloth or
non-abrasive cotton in order to prevent scratching. You can also
buff the lens by holding the frame firmly and moving in a
gentle, circular motion.
