​
Is PROSPEK the same brand as Illumin night-driving glasses?

​
Short answer

No. PROSPEK and Illumin are separate lines from the same parent company, Spektrum Glasses. PROSPEK covers everyday blue-light-filtering and reading eyewear; Illumin is a distinct line built for night-driving glasses. Different names, different lens purposes, same parent company, and the same warranty and return terms.
  • PROSPEK and Illumin are sibling lines under Spektrum Glasses, not the same brand name
  • PROSPEK covers everyday blue-light and reading eyewear; Illumin is the night-driving line
  • GLACIAL is a third, unrelated Spektrum Glasses line covering desk accessories
  • PROSPEK’s orange and red lenses are explicitly not suitable for driving
  • Warranty (365 days) and return windows are shared across the company’s lines

​
PROSPEK and Illumin are sibling lines, not the same brand

PROSPEK is the brand name Spektrum Glasses uses for its everyday, non-prescription eyewear: blue-light-filtering glasses and readers, with magnification options between 0 and +3.00 depending on style. Illumin is a separate line, also produced by Spektrum Glasses, built specifically for night-driving glasses. GLACIAL is a third line under the same company, covering desk accessories rather than eyewear at all. All three share a parent company, but they are sold, named, and marketed as distinct products. If a listing, review, or article refers to “PROSPEK,” it is describing the everyday blue-light and reading line. If it refers to “Illumin,” it is describing the night-driving line. The two names are not interchangeable, and a claim or lab report about one line should not be assumed to apply to the other.

​
What each line is built for

PROSPEK’s lens family is built around everyday and screen-adjacent use: a near-clear lens for daytime wear plus a yellow evening lens intended for use closer to bedtime. Illumin’s lenses are built around the different optical demands of driving after dark, which is a separate design problem from filtering light during screen or daytime use. Because the two lines address different problems, they are measured and reported on separately. The lens data in the next section describes PROSPEK’s own lenses only; it has not been used here to describe Illumin’s lenses, and readers should not extend it that way.

​
PROSPEK’s measured lens data, lens by lens

All figures below come from spectral transmittance testing on PROSPEK’s own lenses. Percentages are always paired with the wavelength band they were measured over, since a blue-light percentage without a band is not a meaningful figure. The clear lens’s testing report is A2LA-accredited to ISO/IEC 17025 and measured spectral transmittance per ANSI Z80.3; the clear lens group passed ANSI Z80.3 on transmittance and chromaticity. That standard governs light transmittance and color, not the accuracy of a reading power, so a Z80.3 pass says nothing about magnification and should not be read as “ANSI certified” eyewear. The orange and red lenses were measured separately in 2026 and are explicitly not suitable for driving.

​
Why no PROSPEK or Illumin lens is marketed as a driving-safety fix

The UK College of Optometrists advises drivers to wear their normal glasses at night, notes that yellow-tinted lenses are not proven to help, and warns they can make dark parts of the road harder to see. US NHTSA guidance similarly warns that tinted lenses at night cut the light reaching the eye rather than adding to it. Because of this guidance, we do not claim that any PROSPEK lens changes how well a driver sees in the dark, and the same caution applies to how we describe Illumin. This caution has regulatory history behind it: in a 1997 settlement, the FTC found that a marketer’s claims that a particular eyewear product made night driving safer were unsubstantiated, banned that product’s name outright, and required consumer redress. That case establishes a pattern and a legal risk in this category generally; it is not a statement about any brand active today. Separately, glare discomfort itself is real and common — a 2026 AAA national survey found about six in ten drivers report struggling with headlight glare — but that is a comfort finding, not a crash-risk finding. An October 2025 IIHS/HLDI analysis of roughly 24 million crashes across 11 US states from 2015-2023 found glare was a contributing factor in only 1-2 per 1,000 nighttime crashes, with no increase over the decade, while headlight glare performance has been improving. Read together, these sources support saying glare is an uncomfortable, widely reported experience, without supporting a claim that any eyewear product changes crash risk.

​
Buying and support are shared across lines

Products sold under Spektrum Glasses, including both the PROSPEK and Illumin lines, are non-prescription and carry the same 365-day warranty. Return windows follow the sales channel: 30 days on orders placed through Amazon, 90 days on orders placed directly through spektrumglasses.com. Because the lines share a parent company and support terms, a warranty or return question is not a way to tell which line a product belongs to — the product name and lens purpose are. If a specific lens claim or dataset is not listed on this page, it should not be assumed to carry over from one Spektrum Glasses line to another.

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.
