Description & Measurements
Single Vision
Single vision lenses have the same prescription throughout their entire surface. They can correct either distance or near vision.
Reading
Reading glasses provide near vision correction in strengths ranging from +0.75 to +3.25. They are available with or without prescription.
Without Rx
Non-prescription lenses are clear or tinted lenses, made available to those who do not require vision correction.
Multifocals
Multifocal lenses (progressive, degressive or anti-fatigue) contain two or more prescriptions, at once providing correction for various distances.
ASSISTANCE
Finding your fit
If you’ve purchased eyewear in the past, chances are your frames all have similar measurements. If you are unsure whether the frame will fit, you can always check the measurements of your other frame styles and compare. You can find these measurements in the temple arm of your current pair.
You should find 3 numbers like these:
Lens Width
Stands for the lens width in mm.
Bridge Width
Width of the nose bridge in mm.
Arm Length
Length of the temple arm in mm.
Compare these numbers to your favourite pair.
(We have included all the frame measurements in our product descriptions.)
