The 50% off promo at the top of this page is the lead offer from Proof Eyewear: the 50% off voucher applies to select sunglasses, optical frames and eyewear essentials and is best if the item you want is in that select range. If your item is not part of the selected styles or you prefer a marked price deal, the other on‑site sales include 35% off warehouse items, 34% off a specific Warehouse Shasta Wood style, fixed price prescription eyewear at $150, and several marked price items (for example, the Aluminum Collection at $14900). Use the 50% promo where it applies; use the marked deals when the item is specifically listed there.
Buying a select frame or pair of sunglasses (typical frames priced like $200). If the frame you want is one of the select styles covered by the 50% off voucher, the voucher gives the biggest saving. On a $200 select frame, the voucher takes 50% off, so the price becomes $100 and you save $100, compared with a 35% warehouse discount which would leave $130 and save $70. The 50% voucher at the top of this page is the one to try at checkout first.
Buying prescription eyewear priced at $150. The marked deal lists prescription eyewear for $150. If the 50% voucher applies to that optical item, the voucher reduces $150 to $75, saving $75, which is better than paying the $150 marked price. If the voucher does not include that prescription style, the $150 deal is the clear choice.
Buying an identified warehouse style such as Warehouse Shasta Wood. The page lists a 34% off coupon for Warehouse Shasta Wood and a broader 35% warehouse sale that can apply to already discounted products. If the specific Shasta Wood pair is the item you want and the 35% warehouse sale also covers it, 35% will save a little more than 34% on that SKU. For items already discounted, prefer the 35% warehouse coupon where it is explicitly shown to apply.
Buying low cost accessories or gift cards. For gift cards starting at $20, the 50% frame voucher will not help unless the gift card is among the select items. The 10% signup discount from the newsletter is only for first purchases and is best used on small orders where the 50% voucher does not apply.
Our records for the 12 months to October 2026 show 16 offers listed for Proof Eyewear, with three percentage codes in that time and the biggest at 50% (August 2026), and the typical percentage code being 50% off. Our team performed three checkout tests across three offers in the 12 months to October 2026, with two tests kept as screenshots.
When choosing, calculate the total each way using the original price, then the discount in order, and take whichever leaves the lower final price. Note that some deal listings say they cannot be used with other promotions; for example the FLV/F4V converter offer explicitly cannot be combined with other promotions, so do not expect to stack that with the voucher.
