How are TheraSpecs different from other blue light glasses?

Most glasses marketed as blocking blue light only focus on a narrow band of blue light and also typically do not filter as much blue light compared to TheraSpecs lenses, which are specifically designed to target it. Choosing from our lineup of blue-blocking lens options is going to give you the specialized protection you need for whatever lighting gives you trouble.

• TheraSpecs Flex is our recommendation for people who want excellent screen or computer glasses with a minimal tint and/or if you want to use them to combat headlights while driving at night. We also suggest Flex if you are mildly sensitive to light.
• Contrast HEV is also an excellent choice for screen use, as it filters out high-energy visible light, which our eyes struggle to focus well.
• If you’re living with more prominent symptoms of light sensitivity, we recommend you add FL-Pro to your light management plan for extra protection against harsh blue light. In fact, it filters up to 25 times more of the problematic wavelengths when compared with clear- or nearly-clear blue light lenses.¹ FL-Blend provides similarly targeted shielding, but trades some protection for a softer plum-colored tint. Both styles target blue light near 480nm to keep you protected against screens, fluorescents and LEDs, and other artificial sources.

Designed to block all disruptive blue light, our Sleep lenses specifically target the wavelengths that may affect melatonin production and sleeping patterns. Wear them for 2-3 hours before your bedtime so that you may maximize their sleep-enhancing benefits.
