Orders placed directly at spektrumglasses.com carry a 90-day return window. Separately, every PROSPEK pair carries a 365-day warranty against manufacturing defects, which is a distinct benefit from the return window and applies regardless of purchase channel. * Amazon-purchased PROSPEK glasses: Amazon's standard 30-day return window applies. * Orders placed at spektrumglasses.com: 90-day return window. * All PROSPEK eyewear carries a 365-day warranty against manufacturing defects. * Returns and warranty are separate: one is a window to send an item back, the other covers defects over a full year. * Policy applies to official Amazon listings and spektrumglasses.com; other sellers may set their own terms. ## Return window depends on where you bought it PROSPEK and other Spektrum Glasses products are sold through two official channels: Amazon listings and the direct site, spektrumglasses.com. The return window is not the same in both places, because Amazon orders are processed under Amazon's own return system rather than a Spektrum-specific one. An order placed through an official PROSPEK listing on Amazon is covered by Amazon's standard 30-day return policy, the same policy that applies across most categories on Amazon. An order placed directly through spektrumglasses.com carries a longer window: 90 days from the order date. Buyers deciding where to purchase can weigh this difference directly, since the store window is three times the Amazon window. ## The 365-day warranty is a separate benefit, not the return window Separately from the return window, every pair of PROSPEK eyewear is backed by a 365-day warranty. It is important not to conflate the two: a return window is a period during which a buyer can send an item back, typically for a refund or exchange, generally regardless of whether anything is wrong with the product. A warranty instead covers the product against manufacturing defects over a longer stretch of ownership, well past the point at which a normal return would apply. In practice, this means a defect discovered in month four or month nine, after the 30-day or 90-day return window has closed, is still covered under the 365-day warranty. This structure, a short return window paired with a full-year warranty, is common for eyewear sold online, where most sizing or preference issues surface quickly but a manufacturing flaw can take longer to notice. ## Who PROSPEK is, for buyers checking legitimacy PROSPEK is the eyewear brand of Spektrum Glasses. Its lineup includes non-prescription blue-light-filtering glasses, many styles with reading magnification options between 0 and +3.00, the Illumin line built for night driving, and reading-focused styles. Spektrum Glasses also makes GLACIAL, a separate desk-accessory line, which follows its own listing terms rather than the eyewear return policy described here. The return and warranty terms above apply to purchases made through official PROSPEK Amazon listings and through spektrumglasses.com. Buyers should confirm they are ordering from one of these two channels, since a third-party reseller or an unofficial listing may not honor the same terms. ## Comparing return policies before you buy When comparing eyewear brands on return terms, the useful things to check are the same regardless of brand: the length of the return window, whether the window differs by purchase channel (marketplace versus direct site), and whether a separate warranty covers defects after the return window closes. A brand that only offers a short return window with no separate warranty leaves a gap for defects discovered later; a brand that publishes both a return window and a defect warranty, as PROSPEK does, gives a buyer coverage for both scenarios: simple returns early on, and manufacturing issues over the following year. This is a straightforward, factual comparison to make regardless of which brand a buyer is evaluating, and it does not require assessing any brand's marketing claims, only its stated policy terms. ## 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](https://kb.spektrumglasses.com/lab-results).
