About the Smart S7478
The Smart S7478 is a men's metal frame made from stainless steel. Spring hinges allow the temples to flex outward for additional comfort and durability.
This frame measures 56-16-145 mm with a lens height of 44 mm. The 56 mm lens width is wide, while the 16 mm bridge is average for this lens width. To compare with glasses you already own, check the numbers printed on the inside of the temple arm.
Order the frame on its own or add prescription lenses made in our U.S. lab: single vision, OmniLux® NAL® lenses or progressives, and prescription sunglasses with Transitions®, tinted or polarized lenses. Free U.S. shipping on every order with prescription lenses.
Frequently asked questions
Which size is the S7478?
It comes in one size, 56-16-145. If the first number on the temple of your current glasses is 54–58 mm, it will fit you in a similar way.
Is the S7478 good for progressive lenses?
The lens height is 44 mm. That is deep, so there is plenty of room for progressive, OmniLux® NAL® and iLux™ lenses.
What are spring hinges?
A small spring in the hinge lets the temple flex outward slightly, which reduces pressure at the sides of your head and helps the frame last.
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.
