Clip-on sunglasses are not
really sunglasses at all. They
are an arrangement of a pair of lenses
specially designed to fit on top of another
pair of glasses or even sunglasses. When you attach
clip-on sunglasses to any
pair of glasses, you change them into something totally different and
very
special. Whether looking for clip-ons or full sunglasses choosing designer sunglasses
will
be a good choice to protect you.
Clip-on sunglasses are comprised
of two separate lenses
attached by a spring mechanism. Each
individual lens is designed with a rod and
a tube pointed towards the nose in a way that allows the
rod of one lens to enter
the tube of the other lens. Both lenses
are held together by a spring
mechanism. This arrangement helps to increase or
decrease the linear distance between the two
lenses. They can be fitted over
the nose to attach to an existing pair of sunglasses.
A new style of clip-ons has a mechanism to attach them to a
hat. The wearer then has full use of
the lens without suffering any discomfiture from the side rims. Magnetic
clip-on
sunglasses provide
an advantage by attaching directly to the rim of the
existing glasses. They are rarely slip off and are
convenient to put on.
Clip-ons are also available as a flip-clip, which enables you to flip
the
clip-on
sunglasses up or down as needed. These are
very handy for the sportsman or
anyone in an area
where the
intensity of light fluctuates.
Clip-ons are more than just fashion statements
as they can have
some legitimate purposes. Clip-on
lenses come in a variety of different forms:
polarized, UV resistant, or prescriptive. With clip-ons,
you can change any ordinary
pair of glasses into polarized sunglasses with ease.
When considering the purchase of clip-ons
remember that they
need to be light weight as they are
going to be attached on another pair of
glasses further adding to the weight on your nose and face.
They are often
constructed from glass, polycarbonate, or CR-39. Glass clip-ons can
have the
advantage
of being scratch-resistant but they usually are heavy. Polycarbonate
may be a
good
choice for light weight clip-ons. But CR-39 provides the clearest and best
visual quality. Tints and
shapes of clip-ons can be matched to your existing
pair of glasses as there are a wide variety to
choose from.
When going outdoors, wearers of prescription glasses can instantly
convert their lenses into
something fashionable and functional by
attaching a
pair of clip-ons. The clip-ons are ideal for glare
prevention and eye
protection while maintaining high quality vision from
the user’s prescription
glasses.
Clip-ons are cheaper than other sunglasses
because they lack
a frame. However, the prices can vary
widely based on brand, design and
quality. It is always important to select quality clip-ons to
preserve and
protect your vision while outdoors.
