You can make some huge savings when
buying online with Glasses2you, however you do want
to make sure that you end up with a frame that suits
you. We want to make you as comfortable as possible
with shopping online for your spectacles so, please
familiarize yourself with the following so that
you can be confident about the product you order.!
How To Choose The Correct Frame
Lens Diameter: This
is measured across the lens from the bridge
Bridge: This is the area which sits directly above
your nose
Arm Length: There are three arm lengths that can
be regarded as standard; 135mm, 140mm and 145mm
Frame Width: The total
width across the full frame to give you an overall better picture
of how these frames compare to your current glasses. (This measurement
is for guidance only as it can be slightly adjusted either way by
an optician)
Lens Height: Measurement
from the top to the bottom of the lens. All frames can be fitted
with single vision lenses. However, if you require a bifocal or
varifocal lens, then this measurement becomes important, as multi
focal lenses will require a minimum lens depth of 28mm.
If you already have a pair of glasses that you are
happy with, the process is very simple. You can choose a pair of
a similar style or totally different if you wish. By checking the
frame sizes from your own pair against the sizes indicated on our
site you will be able to purchase a pair of glasses that will fit
comfortably. Please note though, these measurements do NOT
have to be EXACTLY the same, just very
similar will do. One or two millimeters difference should not make
too much difference.
Take a look at the inside of the arms of your glasses.
You will see something like 48 [] 17 135 , occasionally
written as 48 [] 17 without the arm length. This
is because the arms are straight with no curve at the end and also
because the arms are quite easily adjusted. You may also find these
measurements on the inside nose bridge but more often than not it
will be on the arm. These numbers relate to lens diameter,
nose bridge width and arm length. The
measurements indicated in red
in the graphic above are extra measurements we encourage you to
take yourselves and will not appear anywhere on your glasses. All
the products on our site have these extra measurements indicated.
There may be other numbers and codes on the inside
of the arms. These are just manufacturers codes for styles and colours.
You can ignore these.
This tells you that the lens diameter is 48mm,
the nose bridge gap is 17mm and that the arm length
is 135mm.
Now compare these measurements against
the glasses on our web site and you will get a
comfortable fitting pair of glasses!
