Where Eyewear catalogs go wrong
These are the recurring catalog problems ShelfMerge finds across Eyewear stores on Shopify. Most stores have at least two of them active at any point — and most operators don't know until they pull a real inventory health report.
Frame color and style variants proliferate rapidly — tortoise, black, and clear frames dominate while novelty colorways sit
Prescription vs non-prescription lens variants create catalog complexity and inventory planning challenges
Trend-driven frame shapes (oversized, geometric, cat-eye) peak fast and leave dead stock when the trend shifts
Near-identical sunglasses listings for different light transmission levels (mirrored vs polarized vs standard) split the same buyer
Seasonal patterns in Eyewear
Summer (May–August) is the peak for sunglasses. Back-to-school and fall drive fashion eyewear. Q4 sees prescription glasses and gifting spikes. January and February are the softest periods for most eyewear categories.
Eyewear stores that don't adjust reorder timing around their seasonal cycle are the most likely to accumulate dead inventory after peak periods end. The pattern is consistent: over-order into peak, under-clear after it, and carry the dead stock into the next cycle.
Benchmark
Eyewear stores on Shopify average a 4.6x annual inventory turnover ratio. Stores with a catalog health score above 80 (as measured by ShelfMerge) turn inventory at 6.0x or higher. Stores below a 60 health score average 3.0x or less, with dead stock accounting for 20% of catalog SKUs.
The single most important thing Eyewear stores get wrong
Eyewear frame color performance follows a narrow bell curve. Across most eyewear categories, 3–4 frame colors drive 80%+ of sales. Run a frame color velocity report before every reorder and eliminate colors that haven't hit minimum velocity in 90 days.
How ShelfMerge handles Eyewear catalog problems
ShelfMerge connects to your Shopify store in 30 seconds and runs five analysis engines across your Eyewear catalog. Here is what each one surfaces:
Dead inventory scorer
Every product in your Eyewear catalog is classified as thriving, slowing, dying, or dead — based on sales velocity, days since last sale, and current stock levels. You see the dollar cost of what isn't moving.
Variant performance report
Surfaces every zero-sale variant across your catalog — size runs no one buys, colors that never ship, flavor extensions that sit. Stop restocking options your customers consistently ignore.
Cannibalization detector
Identifies products that are competing for the same buyer using Pearson correlation on weekly order data. For Eyewear stores, this is especially relevant where similar product titles split the same customer across multiple listings.
Catalog health score
A single 0–100 score updated weekly from dead inventory weight, missing images, dead variants, duplicates, and cannibalization severity. Track your trend over time — not just a snapshot.
Weekly intelligence digest
Get an email alert when your health score drops, new dead inventory appears, or a cannibalization pair emerges. Stay on top of catalog decay without logging in every day.
