Compare Small, Medium, and Large by the supply ranges shown on Amazon, then verify one unopened blister pack from your current supply. Capacity depends on pack shape, so this chart does not promise universal brand fit or an exact count.
Amazon currently lists the supply windows below. Treat them as comparison ranges. The actual number of unopened packs that fits can change with blister shape, how the packs are arranged, and packaging revisions.

Not established
Sturdysight fits all brands of daily-disposable blister packs and is waterproof. Exact capacity still varies with pack shape and packaging generation, and this guide does not claim a best-selling size.
Selection method
Choose a staging window, compare your current unopened pack with the product photos, and pick more room when the pack comparison or desired count is close.
Evidence checked July 29, 2026. Review the current Amazon listing (opens in a new tab).
Use the active supply you want visible between refills. Leave sealed backup cartons out of the count if they will stay elsewhere.
Use a blister from the product and packaging generation you currently receive. A brand name alone does not establish pack dimensions.
Look at the pack orientation and available room in each product photo. Choose the roomier option when the comparison is close.

The Amazon Small page currently contains conflicting fit language. Its title and product content use all-brand wording, while its sizing section names Acuvue, Precision1, and BioTrue and says other brands are still being tested. This does not establish a fit guarantee for every SKU or packaging generation.

Use an unopened blister from the exact supply you currently wear. Confirm the full product name, compare the pack shape with the product listing photos, and choose more room when the comparison is close. Recheck after a packaging change.
