Private comparison tool
Contact lens cost comparison calculator
Compare the same exact 12-month box quantity across retailers. Enter current checkout costs and only the rebates or insurance benefits already confirmed for that order path.
Your order and retailers
Enter the same brand and box count for each retailer so you compare like for like. Everything is calculated in your browser. Nothing is uploaded.
Copy the quantity from your order history or planned order. This tool does not infer it from a generic replacement schedule. Keep the quantity identical for every retailer.
Leave a retailer's price blank to skip it. Enter shipping, taxes, and mandatory charges from the current checkout. Enter a rebate and insurance benefit only when the retailer confirms both apply to the same comparison. FSA and HSA funds are payment sources, not discounts.
All-in annual cost
Enter boxes per year and at least one price per box to see your comparison.
Use exact inputs, not retailer assumptions
The output is only as reliable as the entries. Product identity, quantity, checkout charges, benefit eligibility, and offer combinations must all refer to the same current order.
| Input | What to enter | What to avoid |
|---|---|---|
| Exact box quantity | Use the same brand, box size, and 12-month quantity for every retailer. | Copy the quantity from your order history or plan. The calculator does not infer it from a generic lens schedule. |
| Current price and fulfillment charges | Enter the current price per box, shipping, taxes, and mandatory checkout charges. | Do not use a search snippet or an expired cart as the final amount. |
| Membership or annual fee | Include the share of a required fee that you want this comparison to carry. | Use the same allocation rule for every option and document it in your copied notes. |
| Confirmed rebate | Enter only a rebate whose product, quantity, purchase date, and submission terms you verified. | Do not assume a rebate combines with insurance, a price adjustment, or another promotion. |
| Confirmed insurance benefit | Enter the benefit amount the retailer or plan confirms for that exact order path. | FSA and HSA funds are payment sources, not retailer discounts, so they are not subtracted here. |
Benefits and payment sources are different
A confirmed insurance benefit can reduce the amount you pay for a particular order. Rebate eligibility depends on current terms. Do not assume those two values combine.
FSA and HSA funds are different. They are accounts used to pay eligible expenses and may provide tax advantages, but spending account funds does not change the retailer's price. That is why this calculator does not subtract FSA or HSA payment.
For current federal account rules, review IRS Publication 969. Confirm personal tax and benefit questions with the plan administrator or a qualified adviser.
Five comparison mistakes to avoid
Comparing different quantities
Use the same product, box size, and box count for every retailer. A lower box price is not comparable when the quantity differs.
Counting an unverified offer combination
Enter a rebate and insurance benefit together only when current terms or the retailer confirm both apply to the same order.
Treating FSA or HSA payment as savings
Eligible FSA and HSA funds may provide tax advantages, but spending those funds does not lower the retailer's price. Do not subtract them as a discount.
Leaving out checkout charges
Add shipping, taxes, membership allocation, and mandatory charges that apply to the same order quantity.
Confusing lens care with pack organization
Sturdysight is only a dry organizer for unopened daily-disposable blister packs. It never stores a worn lens, bare lens, or solution.
Frequently asked questions
What does the contact lens cost calculator compare?
It compares the totals you enter for the same exact box quantity across up to three retailers. The formula adds box price, shipping, taxes, mandatory charges, and allocated membership fees, then subtracts only the rebates and insurance benefits you confirm are eligible together.
Does the calculator pull live retailer prices?
No. Retailer prices, fulfillment terms, eligibility, and offer combinations change. Copy current values from the exact product and checkout path you are evaluating.
How many boxes should I enter?
Enter the exact number of boxes you plan to buy over 12 months for both eyes. Use order history, a retailer plan, or your eye-care professional's instructions. The tool does not choose a medical replacement schedule or annual quantity.
Can I subtract a rebate and insurance benefit together?
Only when current terms or the retailer confirm both apply to that exact order. If eligibility is uncertain, compare separate scenarios instead of assuming a stack.
Should I subtract FSA or HSA funds?
No. FSA and HSA funds are payment sources. They may have tax advantages when used for eligible expenses, but spending them does not reduce the retailer's price. The calculator subtracts only a confirmed insurance benefit.
Does this tool store my prices or benefit amounts?
No. The calculation runs in your browser. The entered retailer names and amounts are not uploaded.
Does the lowest entered total guarantee the best retailer?
No. It is a comparison of your inputs, not a retailer recommendation. Confirm product identity, prescription handling, current terms, fulfillment timing, and the final checkout amount before ordering.
Can Sturdysight organize the lenses in this calculation?
Only if they are unopened daily-disposable blister packs. Complete the size finder's product checks and compare your current pack shape with product photos before choosing an organizer.
