Mercer TheraSpecs offer a subtle, rectangular profile with a gently sloping brow for versatile fashion. Mercer also combines an ultra-lightweight design with a highly protective fit; the frame is made of TR-90 and features wider lenses to cut down on the most problematic blue light from the front and side, while the arms use flexible, aluminum materials that reinforce its universal appeal. Mercer is available in four matte finishes: black, acorn (brown) tortoise, garnet red, and space blue.
Mercer weighs in at only 18.4g (indoor) and 17.5g (outdoor), with extremely flexible ear tips for a comfortable fit.
Indoor TheraSpecs are great for wearing near artificial light and while using computer or device screens. Some people also like wearing them outdoors on overcast days. Outdoor TheraSpecs provide more relief than typical sunglasses for bright sunlight. Like all TheraSpecs, the Mercer style:
- Reduces headache and migraine frequency and intensity
- Relieves painful light sensitivity and glare
- Protects you from fluorescent lighting
Mercer TheraSpecs come with a microfiber carrying bag.

Our Lightest Frames
This frame is among the most lightweight in our catalog. While the majority of TheraSpecs frames can be considered lightweight (27g or less), these frames have been specially designed to reduce pressure on the head and face for the most sensitive.
