About Sunglasses
Sunglasses have long been associated with
movie stars and celebrities, at
first to protect their eyes from the bright stage lights and now with the
rich and famous primarily to mask their identity. More recently
sunglasses in the latest shapes, styles and colors may be in vogue as a
fashion accessory. Now sunglasses have become apart of your outfit,
You need a different sunglass everyday to stay up to date with the current fashion.
Sunglasses are also recommended for protection against glare whenever
your outside or exposed to bright lights and are a beneficial defense for
your eyes against ultraviolet radiation which may damage and cause
wrinkles around your eyes.
Protection for your eyes
Prolonged exposure to solar ultra violet (UV) radiation may result in
acute and chronic health effects on the immune system, skin and your eyes.
UVA
light has a longer wavelength and penetrates deeper into the skin
than UVB light. UVA light is thought to be a prime cause of
wrinkles. High intensities of UVB light are hazardous to the your eyes, and exposure
may lead to cataracts, pterygium , and pinguecula formation.
Most sunglasses lenses are made of high-grade shatterproof
polycarbonate (Polycarbonate lenses are the lightest) and features glare
blocking and anti-reflective coating. Lenses also offer the maximum UV 400 protection which blocks 100% UVA,
UVB and harmful short-wave blue light from your eyes.
Here are some things you should consider when
purchasing sunglasses.
All though faces come in many shapes and sizes the relationship of your
eyes and ears are about the same, and because sunglasses may take months
to manufacture they come in standard dimensions.
The dimensions for all sunglasses are about the same 5.5" wide, from
one arm of the frame to the other arm. Each arm length is 5" but the
total length of the sunglasses from the front of the frame to the arm
extension about 6.5", this is because of the curvatures of the frame
itself an inch and a half.
Lenses comes in an array of shape and size. The average height of
the lens is 1.5" and 2.5" for oversize lenses which you will find many
celebrities wearing today.
Sunglasses styles
There are three common styles: full frame, half frame, and frameless.
- Full frame - the frame all around the lenses.
- Half frames - the frame only goes around half the lens
- Frameless - no frame around the lenses and arms are attached
directly to the lenses
Nylon or metal frames
The frames are coated for advanced protection and made of high quality
carbon nylon which is durable, light weight and flexible. They are
able to bend slightly and return to their original shape instead of
breaking when pressure is applied to them. The metal or metal alloy
frames are more rigid, some models have spring loaded hinges and many of
the sunglasses are fitted with a rubber memory strip for a snug fit.
Colors and Shades
The shades of colors may be very
subtle; a light or dark lens, a plain or pattern frame, a solid
translucent crystal colored arm. So, look for sunglasses that come in
a variety colors,
you will find them
here. The lenses for example come in a fire
plasma, ice blue, brown, grey or black. The colors on the frame and
arms will vary also. It is important to wear sunglasses that match
the colors of your cloths, a different outfit and a matching pair of
sunglasses because sunglasses can give you a little attitude, change your
mood and accent your personality. |
