Screens emit blue light across a wide range of the visible spectrum, and many LCD and LED screens also produce an invisible pulsing that light-sensitive people can respond to strongly. Precision-tinted lenses work by filtering the specific wavelengths responsible for this discomfort rather than dimming everything equally.

TheraSpecs is the most trusted source for precision-tinted glasses for computer and device screens, offering a range of lenses that target the most irritating of those wavelengths, along with other lens options that address different parts of the blue light spectrum. This includes subtler tints for milder sensitivity and a lens made for screen time in the hours before bed. Every TheraSpecs lens also includes anti-reflective coatings and blocks 100% of UVA and UVB light for even more protection.

The right lens depends on how strong the sensitivity is and when or where screens are used most.

TheraSpecs FL-Pro uses the FL-41 tint to filter the wavelengths between 480-520nm that are most associated with light sensitivity, and it offers the strongest filtering in this range for people who find screens the most difficult. FL-Blend uses the same tint in a softer plum color, trading some of that filtering for more natural color perception. Flex is the most subtle of these options and suits milder sensitivity or a gradual introduction to a tinted lens.

Contrast HEV and Sleep address different parts of the blue light spectrum. Contrast HEV filters the high-energy blue light below 455nm that eyes do not focus well, which may help create better visual contrast and screen comfort. Sleep filters 100% of the blue light that can affect melatonin production and is meant to be worn exclusively for screen time in the hours before bed.

Several of these lenses are also available in multiple strengths to match your level of sensitivity. To narrow down both the lens and strength, the TheraSpecs lens assistant provides a personalized recommendation.

Yes. Phones, tablets, televisions, and computer monitors all emit the same harsh wavelengths, so the device itself is not what determines which lens to choose. That comes down to the specific sensitivity and severity that is being addressed.

Precision-tinted lenses can help manage the intensity of the visuals on the screen, minimize the impact of any invisible flicker, and reduce exposure to the irritating wavelengths the screen emits.

Yes. Gaming tends to mean long, uninterrupted sessions in front of a bright display, often in a dim room, which makes total light exposure higher than typical screen use.

TheraSpecs offers lens options for whichever part of the gaming experience causes discomfort: stronger filtering of the harshest wavelengths a display emits (FL-Pro or FL-Blend), a subtler tint that takes the edge off without much change to the picture (Flex), or a lens that supports visual sharpness during long sessions (Contrast HEV).

Yes, and the right lens depends on what evening screen time is affecting. TheraSpecs offers its Sleep lens that is designed exclusively for screen use before bed, filtering 100% of the blue light that can suppress melatonin production and delay the body's readiness for sleep. It is worth reaching for when watching TV, scrolling, or working late has an effect on winding down.

For visual discomfort that continues into the evening rather than anything sleep-related, FL-Pro and FL-Blend remain strong options for more intense sensitivity to screens. Ambient lighting is often dimmer at night though, so a subtler tint can be the more comfortable choice. Flex takes the edge off harsh screen light with a very soft tint, and Contrast HEV can increase sharpness and contrast when the surrounding light is poor.

Yes. Screens and overhead fluorescents and LEDs emit many of the same problematic wavelengths, so a lens chosen for screen use can protect against the ceiling lights at the same time. That combination is worth accounting for in workplaces where the lighting cannot be adjusted and the exposure lasts the full day.

FL-Pro filters the most of this light and is the strongest option for people who find artificial light difficult generally, not only screens. FL-Blend can also provide support for fluorescent light sensitivity as well as screen and computer use.

Some, yes, although most people adjust to the shift within a short period of regular wear. And with the exception of the Sleep lens, TheraSpecs screen and computer glasses still allow all colors of the spectrum to come through.

Because several lenses come in multiple strengths, the balance between filtering and color perception can also be set to preference. A lighter strength of the same lens shifts color less, and subtler lenses trade more of that filtering for more natural color perception. FL-Blend uses the FL-41 tint in a softer form when compared with FL-Pro, and Flex is an even more subtle tint, making it the better choice if color accuracy matters for the work being done.

Yes. Every TheraSpecs lens includes an anti-reflective coating, which cuts the reflections that form on the lens surface from a bright display or overhead lighting behind you.

Glare and problematic wavelengths are separate problems though, and the tint handles the second. Reducing how much light passes through the lens also brings down the overall intensity of a bright display, which is why a stronger lens can feel easier on the eyes in a brightly lit room.

Yes. Screens are one of the most common sources of difficult light for people whose sensitivity is heightened, including those living with migraine or recovering from a concussion. Not all wavelengths matter equally though, which is why filtering the narrow range most associated with light sensitivity does more than simply dimming the display.

FL-Pro and FL-Blend filter the wavelengths between 480-520nm that drive much of this discomfort, and both are available in multiple strengths so the level of filtering can be matched to the level of sensitivity.

Yes. There is a well-established body of research identifying which wavelengths across the blue light spectrum are most associated with light sensitivity and visual discomfort, along with research documenting the invisible pulsing that many LCD and LED displays produce.

The TheraSpecs team reviewed this body of published, peer-reviewed research to develop a catalog of precision-tinted lenses that filter the most problematic wavelengths that screens emit, with options for different sensitivities and different times of day. Because the lenses are built on that foundation, TheraSpecs are regularly recommended by neurologists, occupational and physical therapists, and other medical professionals for managing sensitivity to screen and computer light.

Yes. TheraSpecs are sold as non-prescription glasses by default, and any lens can also be made with a prescription or with reader magnification. TheraSpecs also offers fitover styles like Original WearOver, Esme WearOver, and Tatum WearOver, designed to be worn comfortably over prescription eyewear already in use.

For anyone who prefers a frame they already own, the Send in Your Own Frame option allows TheraSpecs lenses to be fitted into it.
