Case Studies

Real specifications. Real failures. Real fixes.

One client received polarized lenses at the wrong tint density. Another found logo peeling on temple tips after three weeks. Here's how we diagnosed both failures and rebuilt their specs.

Challenge 01
“Ordered 3,000 sunglasses for our summer music festival. The lenses scratched within hours, and half the frames cracked at the hinges by day two. Sponsors noticed attendees tossing them — with our logo still visible in trash bins.”
Sarah Chen
Sarah Chen Senior Brand Manager, Outdoor Festival
Engineered Solution

Switched to TR-90 frames with hard-coated lenses and spring hinges. Added branded microfiber pouches as standard packaging — attendees kept both the sunglasses and the pouch, doubling brand impressions per unit.

Challenge 02
“Needed 10,000 pairs across six resort locations — polarized for beach properties, fashion for city hotels. Previous supplier sent everything in one tint, one size. Guests complained about glare and poor fit. Wasted 40% of budget on unusable inventory.”
Marcus Rivera
Marcus Rivera Procurement Director, Resort Chain
Engineered Solution

Segmented the order by property type — polarized floating frames for beach resorts, classic TR-90 for city hotels. One vendor, one quality standard, one brand look across all six locations.
