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. Indoor TheraSpecs are great for wearing near artificial light, such as fluorescents and LEDs, and while working on a computer. Some people also like wearing them outdoors on overcast days. Outdoor TheraSpecs are darker, polarized and offer protection for bright sunlight. All TheraSpecs are 100% UVA/UVB (UV400) blocking and use the FL-41 tint. Mercer TheraSpecs come with a microfiber carrying bag.

Designed for light sensitivity protection: TheraSpecs target blue light near 480nm, the most harmful wavelength for light-sensitive conditions like migraine, concussion, dry eyes, and vestibular disorders. Our advanced blue light filtering means your eyes and brain can feel protected even when exposed to triggering light.
25x more protection: TheraSpecs remove as much as 25 times more blue light at 480nm than typical blue light glasses with clear- or yellow-tinted lenses. They also filter more across a wide range of harmful blue light so you stay protected against screens, fluorescent lighting, and LEDs.
Feel the difference: Tens of thousands of people have chosen TheraSpecs, and they have a 96% satisfaction rate for light sensitivity protection and symptom relief after 3 weeks of use. Thousands of headache specialists, neurologists, and physical and occupational therapists recommend TheraSpecs for their patients.
