The formula
Cost per wear = (lens cost + solution cost + case cost) divided by the number of wears. Use a realistic wear frequency, not the maximum the box allows.
Daily example
A ten-pack at 15 dollars is 1.50 per wear, with no solution or case cost.
Monthly example
A pair at 20 dollars plus 6 dollars of solution per month is about 0.87 per day if worn daily, but 3.25 per wear if worn twice a week.
Six-monthly example
Lower unit cost, but the break-even only arrives with frequent wear and disciplined cleaning.
The hidden cost
Infection treatment and lost lenses. Simpler cycles have fewer failure points, which is part of the economics.
Frequently Asked Questions
Which cycle is cheapest?
It depends on frequency. Daily wins below about three wears a week; monthly wins above that.
Do I need to include solution?
Yes, or the comparison is not honest.
Is a higher price worth it?
Only if the fit, cycle and clearance are better. Price alone does not improve comfort.
