What must stay the same when you switch
Three numbers decide fit: base curve (BC), diameter (DIA) and the printed area (graphic diameter). If your current pair sits comfortably, write those numbers down and match them. Changing store does not mean changing fit.
What can change safely
Colour, design and replacement cycle can change without affecting fit. Moving from monthly to daily lenses changes your routine, not the curve.
Where Lensora fits as an alternative
Lensora ships to the US, UK, Germany, Japan and Singapore, lists DIA, base curve, water content and replacement cycle on every product page, and accepts returns within 30 days on unopened boxes. The catalogue is smaller than the big retailers - the trade-off is clearer specification data and one shipping promise per market.
How to check a seller in two minutes
Open any product page and look for DIA, BC, water content and replacement cycle. If any of the four is missing, the seller is not giving you enough to match your current fit. Then read the return page.
Compare price per lens, not per box
A 2-pack and a 10-pack are not comparable at face value. Divide the price by the number of lenses, then by wear days. That is the only number worth comparing across stores.
Frequently Asked Questions
Can I switch stores without a new fitting?
Yes if BC, DIA and material class stay the same. If the base curve changes, start with short wear times.
Are alternatives cheaper?
The like-for-like comparison is price per lens, not per box.
Do I lose quality by switching?
Not if the replacement cycle and material match what you already wear.
