Do you offer bifocal lenses?
We do not offer bifocal lenses, but if your optometrist has written this type of prescription for you, we can fill them as progressives (similar to no-line bifocals) or as single-vision.
Where can I find my frame’s measurements?
On each product page, the frame measurements are listed as three numbers. The first number refers to the width of one lens in millimeters, the second number to the width of the bridge, and the third to the length of one of the temple arms.
Most glasses (including all Visual Mass frames) have these numbers printed on the inside of the temple arm or above the frame structure.
Where can I get my Visual Mass frames adjusted?
If your Visual Mass frames don’t fit you perfectly, our skilled opticians would be happy to adjust your frames at some of our stores.
What’s the best way to clean my lenses?
To thoroughly clean your lenses, simply rinse them with a mild dish soap and lukewarm water, and dry them with a soft cloth. For day-to-day cleaning of light smudges, a few swipes of the cleaning cloth included in your case should do the trick.
Please be careful to avoid using hot water on your lenses (especially if they are high-index lenses), as they can develop bubbles or cracks when exposed to high heat.
