Classic Semi-Rimless Bifocal Sunglasses

These Mass Vision Executive frames combine distance sun protection with a +2.50 reading segment in a single unisex pair. The tortoise metal brow-line design suits adults who want one pair for driving, beach days or outdoor tasks without switching glasses.

Glare-Free Vision All Day

Polycarbonate shatterproof lenses block 100% UVA and UVB rays, eliminating glare that causes strain during long periods outdoors. The bifocal segment stays clear for close work while the upper lens handles bright conditions, reducing fatigue from morning to evening.

Check Fit Before Ordering

Frame measurements are 59 mm lens width, 44 mm lens height, 21 mm bridge and 142 mm arm length. Verify these dimensions suit your face width and nose bridge. The included case protects the lenses when not in use.

Questions about this item

How much heat builds up behind the 59 mm polycarbonate lenses during all-day wear in direct sun?

The 59 mm polycarbonate lenses block 100% UVA and UVB rays, so absorbed solar energy stays low and the frame remains comfortable for extended outdoor use.

What vision correction must the wearer already have for the +2.50 bifocal segment to work properly?

The lower segment adds +2.50 dioptres for near tasks; the upper area has no magnification, so the wearer needs normal distance vision or a separate distance prescription.

Will the 21 mm bridge and 142 mm arms fit the same as the brow-line frames I wore years ago?

The 21 mm bridge and 142 mm arms match classic Executive brow-line proportions, so fit should feel familiar if your previous pair shared those dimensions.
