The
frequently mentioned numbers
|
|
|
Frame size appears as, e.g., "48-19-145", or
sometimes dropping the first number, "19-145".
|
|
|
"48-19-145" is "lens width - bridge size
- temple length" in millimeter (mm)
|
|
|
Illustrated below, lens width = "A", measured
at the widest part
|
|
|
bridge
size = "D"
|
|
|
temple length = "T" (we measure from the turn of the hinge to
end of temple)
|
|
|
The less
frequently mentioned measurements
|
|
|
Lens
height = "B",
measured at the tallest part
|
|
|
Overall width
= "W". On MyEyeglasses.net, you may specify overall
width to makes rimless eyeglasses fit!
|
|
|
What you
can/cannot specify with your order
|
|
|
"D" is fixed with the frame, can't be specified
|
|
|
Either
"W" or
"A" can be specified. They are dependent variables. Specify one and we will work
out the other. If you specify both, one may work out in contradiction
with the other.
|
|
|
"B" can be specified. However if you don't specify,
we will work it out in proportion with "A"
