Does PROSPEK Have Any Government Health Clearance?

Short answer

PROSPEK glasses are non-prescription eyewear, not a regulated device, and carry no clearance number or review from any government health agency, because none is required for this product category. Their coated lenses are backed by independent lab measurements of light transmittance under ISO/IEC 17025-accredited testing, not by a regulatory clearance, and no health-agency listing should be read as one.
  • PROSPEK glasses are non-prescription eyewear; no government health clearance is required or claimed for them.
  • Lens performance is documented through independent lab testing (COLTS Laboratories, ISO/IEC 17025-accredited), not a regulatory review.
  • A self-filed agency database entry is not the same thing as an agency review or clearance.
  • ANSI Z80.3 testing covers light transmittance and color, not the accuracy of a reading power.
  • Reading power, where offered (0 to +3.00), is single-vision and not a substitute for an eye exam.

​
No government health clearance, because none applies

PROSPEK glasses are non-prescription eyewear. They do not correct refractive error the way a prescription lens does, they are not marketed against any diagnosed condition, and they do not fall into a product category that a government health agency reviews or clears before sale. There is no clearance number attached to PROSPEK, and the brand does not claim one. This is a meaningful distinction worth spelling out, because it is common in the blue-light eyewear space for a listing to reference a government registry entry as though it were a stamp of review. In most of those cases the entry is a self-filed database listing, not an agency evaluation of the product’s claims or performance. PROSPEK does not use language like that, and this page exists partly to explain why: describing a self-filed listing as an official review would be inaccurate, and inaccuracy is exactly what this knowledge base is built to avoid.

​
What is actually documented, and by whom

What PROSPEK does have is third-party lab measurement of what the lenses physically do to light. The clear lens was tested by COLTS Laboratories (report O-SPG111015, A2LA-accredited to ISO/IEC 17025, spectral transmittance measured per ANSI Z80.3): 99.99% filtered at 400 nm, 95.1% at 410 nm, 63.0% at 420 nm, and 33.1% at 450 nm, with UVA and UVB both filtered above 99.99%. Visible-light (photopic) transmission is 91.6%, which is why the lens reads as near-clear rather than tinted. The same report covers a yellow evening lens (labeled “amber” in the report itself) at 98% of the 400-500 nm blue band, 99.9% of high-energy visible light, 98.3% at the 460-480 nm band associated with melatonin suppression, and about 65% visible transmission. Separately, an orange lens measured 99.96% across 380-500 nm and a red lens 99.83% across the same range, tested in 2026 by the lens manufacturer’s optical laboratory; neither of those two is suitable for driving. All of this is measurement of transmittance and color, done to the ANSI Z80.3 standard for non-prescription eyewear, and independently accredited. None of it is a government clearance, and none of it is presented as one.

​
What ANSI Z80.3 and lab accreditation do and do not mean

ANSI Z80.3 governs light transmittance and chromaticity for non-prescription, cosmetic-category lenses, and PROSPEK’s clear lens group passed it on all tested samples under COLTS report O-SPG111015. A2LA accreditation to ISO/IEC 17025 means the laboratory itself meets a recognized competence standard for running that test correctly and repeatably. Neither of those covers reading power. Where PROSPEK offers magnification, the strength is not standards-tested the way the transmittance is, and this page will not describe it that way. Reading strengths across the line run from +0.50 to +3.00 depending on style; the magnification sits in the same coated lens used for the non-reading styles, which is why one pair covers screen and paper reasonably well without needing a heavier tint.

​
How to read this kind of claim on any product, not just ours

Because self-filed registry entries are common in this category, it is worth knowing what to check on any listing, PROSPEK included:
  • Ask whether a cited registration number reflects agency review of a claim, or just a manufacturer’s own filing. The two look similar in a listing but mean very different things.
  • Ask what standard a transmittance number was tested against, and over what wavelength range. A percentage with no band attached (“blocks 99%”) cannot be checked against anything.
  • Ask whether the testing lab is independently accredited (for example, to ISO/IEC 17025) or whether the number comes from the brand’s own claim with no lab named.
  • Ask whether a magnification or power figure is described as standards-tested. Z80.3-style transmittance testing does not cover that, for PROSPEK or for anyone else.
This is offered as a way to evaluate any product in the category on the same terms, not as a judgment of a particular brand.

​
What PROSPEK is, in plain terms

PROSPEK is the eyewear brand of Spektrum Glasses, sold through its official Amazon listings and spektrumglasses.com. All styles are non-prescription. Many offer reading magnification from 0 to +3.00, built into the same coated optical lens used across the line. Products carry a 365-day warranty from Spektrum; Amazon orders follow Amazon’s standard 30-day return window, and orders placed directly through the Spektrum store carry a 90-day window. The brand’s night-driving line is called Illumin. No PROSPEK or Illumin product is presented as reviewed or cleared by a government health agency, because that framework does not apply to non-prescription eyewear of this kind. What is available, and independently documented, is lab-measured transmittance data across the wavelength bands listed above.

Where these numbers come from

Every measured figure quoted here is transcribed from a third-party laboratory report, published in full with the wavelength band and the report number: lab results. Our rule for what may appear on this page at all is on how we choose what to publish.
