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 three matte finishes: black, acorn (brown) tortoise, and garnet red.
Mercer weighs in at only 18.4g (indoor) and 17.5g (outdoor), with extremely flexible ear tips for a comfortable fit.
Indoor TheraSpecs provide great protection from computer and device screens and all artificial light. They can also offer relief outdoors on overcast days. Outdoor TheraSpecs are dark, polarized, and, because of their speciality tint, provide more relief than typical sunglasses for bright sunlight.
With TheraSpecs, you can:
- Reduce headache and migraine frequency and intensity
- Relieve painful light sensitivity and glare
- Lessen other symptoms triggered by light, such as eye strain and dizziness/vertigo
- Stay protected against fluorescent lighting, LEDs and screens (indoor lenses) and sunlight and glare (outdoor lenses)
Mercer TheraSpecs come with a case and a microfiber cleaning cloth.
