measures the entire horizontal front of the frame, from the furthest extended point on either side.
is the vertical height of the lens.
is the part that goes across the bridge of your nose
connect to the front of the frame on either side and rest behind your ear.
is the horizontal diameter of one lens. Doctors may refer to this as “eye size.”
You will find your frame measurement written on the temple of your frame. If its not written there then no problem at all you can easily Do It Yourself with the help of EASYSIGHT guide.
THE FRAME WIDTHTo find the frame width measure the front of frame entirely.
THE LENS HEIGHTTo find the lens height measure the lens vertically at its tallest point.For bifocal or progressive prescription the lens height must be atleast 30mm.
To find the the bridge measurement simply measure the bridge from the edge of one lens to the the other.
THE TEMPLE ARMSMeasure the temple arm from the hinge, that is the folding end of the frame to the bent of the arm and then from that bent to the end of arm, now sum uo both measurement.
THE LENS WIDTHMeasure the lens width by measuring the widest part of the lens. Your lens width must have to accommodate your pupillary distance (PD) to get the “Optical Centre” of the lens.
Measure your PD by using PD Guide.
Your frame would mostly have the measurements written upon their arm.
If it is written there then how will you understand it?
No problem !
EASY SIGHT Read It Yourself guide will help you to read and understand that.
Suppose on your arm this notation is written
54-18-140
– Here 54 is Lens Width i.e 54mm
-18 is Bridge width i.e 18mm
-140 is the Temple arm length i.e 140mm
-Your frame width will not be written on the Temple arm, so for that you can use our measurement guide given above.
