The prices in my original 2019 post are historical, but the method still works: identify the exact contact lens you use, compare the same model and pack size across retailers, calculate the delivered price and then add cashback only if it genuinely lowers the cheapest total.
This is not about changing to whichever lens happens to be on sale. Eye fit comes first. The saving comes from buying the right product more efficiently.
Compare the exact same lens
We compare the same prescribed lens across several retailers. The cheapest seller changes over time, which is why I do not treat any one shop as permanently “best”.
Shipping, multipack sizes, discount codes and cashback can all change the ranking, so I compare the final delivered cost rather than the headline price.
Look behind private-label contact lenses
In 2019 we discovered that a lens sold under our optician chain's own branding corresponded to a CooperVision lens available elsewhere under the manufacturer's branding.
That can happen because some opticians sell private-label or rebranded versions of lenses produced by major manufacturers.
The useful principle is to investigate the actual product: manufacturer, material, base curve, diameter, replacement schedule and other specifications. Do not assume two lenses are identical merely because the same manufacturer makes them, and do not switch products without appropriate professional guidance.

Compare solution separately
Contact-lens solution is another recurring cost. We use the same process: compare the delivered price for the product we want and take cashback if the cheapest retailer also happens to offer it.
Cashback is the last layer, not the first
This matters. A 5% cashback offer does not make an expensive store cheap if another retailer is 15% cheaper before cashback.
My order is:
- Confirm the correct product.
- Compare like with like.
- Include shipping and pack size.
- Apply valid discounts.
- Use cashback if it lowers the already-competitive final price.
Monthly or daily lenses?
Monthly lenses have been cheaper for us in everyday use, while daily lenses can be convenient for travel. That is not purely a price decision, though. Which lens type suits your eyes should be decided with an optometrist or eye-care professional.
We do not economise by skipping eye examinations or contact-lens checks. The saving comes from shopping intelligently for the correct lens, not from cutting the clinical part of eye care.
The bigger frugal-shopping principle
This is the same system I use for many purchases: compare the exact item first, then stack cashback or discounts on top. Small percentages become meaningful when they are applied repeatedly to things you were going to buy anyway.
