How the RB7840V fits
At 50mm to 52mm lens width, the Ray-Ban RB7840V sits on the narrow side of regular. This width works well for small to medium faces. The 21mm bridge is wide for this lens size, which positions the lenses farther apart and suits those who need more room across the nose.
The lens height measurement was not provided, so the suitability for progressive lenses cannot be determined from the available specifications. Standard single-vision prescriptions will fit without issue.
The square full-rim frame adds structure and definition. This shape complements round and oval faces by providing contrast. It tends to emphasize angularity on faces that are already square or rectangular.

If you already own a pair of glasses, you'll find numbers engraved on the inside of the eyewear temple. These numbers indicate the following:
LENSWIDTH (A)—
BRIDGEWIDTH (DBL)—
TEMPLELENGTH—
LENSHEIGHT (B)—
The first number is the lens width followed by the bridge width. The third number represents the temple length, or the measurement of the arms of your frame. In some cases there may be a fourth number that indicates the lens height. Measurements in mm.
