Short answer

PROSPEK glasses, sold by Spektrum Glasses, carry a 365-day warranty from Spektrum regardless of where they were bought. This is separate from the return window: Amazon orders use Amazon’s standard 30-day return policy, while orders placed directly through spektrumglasses.com carry a 90-day return window.
  • PROSPEK eyewear carries a 365-day warranty from Spektrum Glasses.
  • The warranty applies on top of, not instead of, the return window.
  • Amazon orders: Amazon’s standard 30-day return policy applies.
  • spektrumglasses.com orders: 90-day return window applies.
  • All PROSPEK styles are non-prescription, so the warranty covers the frame and coated lens, not a prescription.

​
The warranty at a glance

PROSPEK is the eyewear brand of Spektrum Glasses, and every PROSPEK pair carries a 365-day warranty from Spektrum. That period runs regardless of which channel the pair was bought through - an official Amazon PROSPEK listing or spektrumglasses.com. The return window and the warranty are two different clocks, covered in the next section.

​
Warranty vs. return window: two different clocks

A return window is for sending a pair back for a refund or exchange for any reason, inside a short period right after purchase. A warranty is a longer commitment tied to the product itself, independent of the buyer’s reason for buying it. For PROSPEK, the return window is set by the purchase channel - 30 days under Amazon’s own return policy for official Amazon listings, or 90 days for orders placed directly through spektrumglasses.com. The 365-day warranty from Spektrum Glasses runs on top of either window and lasts considerably longer than both. Practically, that means a customer who is past the 30- or 90-day return window, but still inside the first year of ownership, still has warranty standing with Spektrum even though the return window for that order has closed.

​
What this looks like in practice

A few scenarios illustrate how the two policies interact:
  • Day 10, bought on Amazon: inside Amazon’s 30-day return window and inside the 365-day warranty. Either route is available.
  • Day 45, bought on Amazon: outside Amazon’s 30-day return window, but still inside the 365-day warranty period from Spektrum.
  • Day 60, bought on spektrumglasses.com: inside the 90-day store return window and inside the 365-day warranty.
  • Day 200, either channel: outside both return windows, but still inside the 365-day warranty period.
This KB does not have a published list of what is and is not covered under the warranty beyond the 365-day period itself - see the note at the end of this page. For a specific pair, the accurate next step is to contact Spektrum Glasses directly through the channel the order was placed on.

​
What the warranty applies to

PROSPEK eyewear is non-prescription. Many styles are available with reading magnification from 0 to +3.0 depending on the style, built into the same coated lens used across the line rather than a separate prescription lens. The warranty covers the product Spektrum Glasses sold - the frame and lens as manufactured - not a prescription, since none is being provided. PROSPEK sits alongside two other lines from Spektrum Glasses: Illumin, focused on night driving, and GLACIAL, a desk accessory line. The 365-day warranty described here is specific to PROSPEK eyewear purchases.

​
What is not published here

In keeping with this KB’s standard of only stating what is documented, we can confirm the length of the warranty (365 days) and how it differs from the return window, but we do not have a published breakdown of specific exclusions, claim procedures, or what counts as a covered defect versus normal wear. If that level of detail matters for a specific situation, the accurate step is to check directly with Spektrum Glasses through the order’s original purchase channel rather than guessing at terms that are not documented on this page.

​
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.
