If ordinary sunglasses or lighter specialty filters still allow too much light through, these light sensitivity glasses provide much stronger filtering. NoIR Filter 26 uses a 16% VLT blue lens, meaning only about 16% of visible light passes through.
This makes the lens particularly useful for people with significant light sensitivity who need substantial brightness and glare reduction. The blue filter is associated with conditions including brain trauma / concussion-related light sensitivity, achromatopsia, post-cataract light sensitivity and migraines.
Choose from fit-over frame options designed to be worn over your existing corrective eye wear, including standard fit-over styles and styles with a removable top shield. However, they can also be worn without eyeglasses under them.
These glasses are a much more specialized choice than ordinary tinted sunglasses.
Choose Filter 26 if you:
May be especially helpful for activities such as these:
The 16% VLT makes this lens especially suited to bright environments, rather than typical indoor lighting.
Filter 26 and FL-41 are not the same type of lens.
FL-41 lenses are typically rose or pink and are commonly chosen for migraine, photophobia, computer screens and fluorescent or artificial lighting.
NoIR Filter 26 is a much darker blue specialty filter that allows only 16% of visible light through. It is better suited to someone who needs substantial overall light reduction or who specifically benefits from a blue filter.
Someone mainly bothered by office lighting or screens may prefer FL-41. Someone who finds bright environments overwhelmingly intense even with ordinary sunglasses may need a darker specialty option such as Filter 26.
Yes. These are blue-tinted lenses, so they will noticeably change the color of what you see.
That is intentional. Filter 26 is a specialty medical filter rather than a neutral-color sunglass lens.
If maintaining natural-looking colors is your main priority, another filter color may be a better choice.
Filter 26 is best suited to bright environments where glare and overall brightness are difficult to tolerate.
Possible situations include:
Yes. The fit-over frames are designed to sit over corrective eye wear, allowing you to continue using your regular prescription glasses underneath.
The surrounding frame and side coverage also help reduce light entering around the edges of your eyeglasses.
Both styles are designed to fit over corrective eye wear.
The Standard Fit-Over provides front and side coverage for everyday fit-over use.
The Removable Top Shield adds coverage above the eyeglasses to help reduce light entering from overhead. The top shield can be removed when that additional coverage is not needed.
Measure the outside width and height of the eyeglasses you plan to wear underneath. Your corrective eye wear should be smaller than the fit-over frame so there is enough room for a comfortable fit.

Filter 26 is a good choice when ordinary sunglasses simply do not reduce enough light and a much stronger specialty filter is needed.
