A reading-glass assortment for museums and cultural attractions should provide useful power breadth while protecting the strengths visitors select most often. Equal quantities can tie up space while common powers are unavailable for exhibit text, maps, programs, and mobile guides.
Separate breadth from depth
Breadth serves visitors, members, tourists, and school-group adults. Depth should reflect visitor demographics, program periods, display capacity, and the museum store's replenishment process.
Build the opening curve
- Set the intended range.
- Weight likely core powers more heavily.
- Use labels that are readable and consistent with the store's presentation.
- Keep backstock by power.
- Use visitor requests and reorders to revise the mix.
A Major Frames planning example
Major Frames often gives approximately +2.00 through +3.50 more depth in reader-heavy programs. This is a program example, not a universal standard. Visitor mix and actual movement should determine the final allocation.
Watch for functional out-of-stocks
A rack can look full while common powers are missing. Audit gaps, misplaced frames, aging duplication, and refill stock that has not reached the sales floor.
Use the reorder to improve the assortment
Increase powers with repeat shortages across normal and high-attendance periods. Keep less common powers available without overbuying them.
What to monitor
- sales and requests by power
- visitor-period stockouts
- label and placement issues
- backstock use
- reorder frequency
Over-the-counter readers are not a substitute for professional eye care.
