Find the Sunglasses That Are Right for You
There are so many different types of sunglasses on the market
today that finding the right pair to fit one's needs can be a
very daunting task. The best pair of sunglasses should offer
protection from UV rays, be extremely durable, look good, and
serve any special needs that the wearer might have. Once one has
found the right pair, they should be so comfortable that the
wearer may even forget that he or she is wearing them! There are
a few elements to consider when buying sunglasses. Frame and
lens options, sun protection, and the purpose of the sunglasses
should all be considered.
The frame is essential because it holds the glasses together and
provides comfort and stability. Frames have two parts with
different functions. The glasses are kept firmly on one's ears
via the arms of the frame. The face of the frame keeps the
lenses aligned with the eyes. There are three different types of
frame materials: plastic, nylon, and metal. All of the materials
have different positives and negatives. Plastic can usually be
found in less expensive sunglasses. Unfortunately, plastic is a
lot less durable and cracks more easily than other materials, so
it is a good idea to use plastic reinforced with a metal rod in
the arms. Nylon is a excellent choice because it is flexible,
light and strong. If Nylon is bent, it has the ability to return
to its original position. The final material for the frame is
metal, which is also an excellent choice because it's strong and
lightweight. However, metal will bend and break more easily than
nylon.
The hinge is the part of the frame that holds the arms and face
of the frame together. The two types of hinge materials are
metal and nylon. Both types of hinges are solid. Some hinges
that are not as well made will make the glasses feel brittle and
will have the tendency to not stay snugly on the wearer's face.
For this reason, higher quality hinges should be purchased.
The lens is the most important part of sunglasses. There are
several different types of lenses. Lenses can vary in tint,
material, and coating. Higher quality lenses are generally
preferred because cheap lenses can distort images. A distorted
image causes the eyes to strain. Over a long period of time,
this can lead to prolonged headaches, nausea, and dizziness.
The types of lens materials are glass, cr-39, polycarbonate
plastic, and acrylic plastic. The highest quality of these
materials, and the material suggested for persons concerned
about vision quality is glass. Glass lenses are also the most
scratch resistant, but they are prone to shattering when hit.
The other three types of materials are all plastic and impact
resistant. Acrylic plastic must be specifically treated in order
for it to protect the wearer from UV rays.
Lenses also vary in tint. A darker tint will absorb a
significantly higher amount of light than a lighter tint.
Different color tints also serve different purposes. An amber or
orange tint will reduce blue light which is the chief component
of glare. Therefore, these sunglasses are popular in sports that
have a high amount of glare (boating, fishing, and skiing).
Brown tints are good for driving, and Gray is good for golfing,
running, or cycling. Different tints have different abilities to
reduce glare. The best suggestion is to take the sunglasses use
into consideration when choosing.
Finally, sunglasses have a variety of coatings. UV protective
coatings are a must for sunglasses. The sun's harmful UV rays
can seriously damage eyes. Some sunglasses may have a dark tint,
but do not have special coatings that protect against UV rays.
Other coatings can help improve the scratch resistance on
sunglasses. Additionally, mirror or flash coated lenses, and
anti-reflective coated lenses can greatly reduce the amount of
light absorbed and reduce glare or "halo" effects. Once again,
the coating choice should depend on the intended use of the
sunglasses.
Sunglasses are essential for people in a variety of situations.
Casual sunglasses that are to be used when at the pool or beach
do not have to be the most expensive sunglasses available. For
most people, sturdy sunglasses that protect the eyes from UV
rays and look good are more than enough. However, for anyone who
is doing a sport that requires maximum visibility in sunny
conditions, high-quality sunglasses are a must. Different lenses
and frames can produce highly variant results. Anyone looking
for sunglasses should understand in what context the sunglasses
will be used, and then choose accordingly. An educated decision
will usually result in one choosing sunglasses that he or she is
very satisfied with.
