Is a year supply of contacts worth it, and how many boxes is that?

A year supply of daily contacts for both eyes is about 730 lenses. Lens makers round that to 720, which is eight 90-packs or twenty-four 30-packs. For monthly lenses, a year is four 6-packs, two boxes per eye.

Buying the whole year at once is worth it when three things are true. Your prescription stays valid for the full year. A rebate or a lower price actually applies where you buy. And you can pay for the year up front, or you have FSA money that would otherwise expire.

How many boxes is a year supply?

Assuming you wear lenses every day, both eyes use the same prescription, and you replace them on schedule:

The daily counts cover 720 lenses, which is 360 days per eye. ACUVUE counts 720 lenses as an annual supply of its 1-day lenses. CooperVision's 2026 rebate asks for eight 90-packs or four 180-packs of its MyDay dailies. For two-week lenses, ACUVUE counts 48 lenses as a year, which is eight 6-packs. For monthly lenses, CooperVision's rebate for Biofinity asks for four 6-packs.

If your two eyes have different prescriptions, split the boxes: half for the right eye and half for the left. The full math for any box size is in how long does a box of contacts last.

How much does buying a year save?

Mostly through rebates, and a rebate is money back later, not a lower price today. CooperVision's 2026 current-wearer rebate pays these amounts on an annual supply:

• MyDay dailies: $100 for eight 90-packs or four 180-packs.
• clariti 1 day dailies: $75 for four 180-packs, eight 90-packs, or twenty-four 30-packs.
• Biofinity monthlies: $30 for four 6-packs.
• Biofinity toric or multifocal: $50 for four 6-packs.

The conditions matter as much as the amount. The lenses must come from the eye doctor who prescribed them, or an affiliated location, in a single purchase. Internet retailers, 1-800 CONTACTS and Costco are excluded. You have 60 days from purchase to submit the claim, and the payment arrives as a prepaid card up to 6 weeks later. Other brands run their own programs with their own amounts. The details are in how do contact lens rebates work.

So the real comparison is the office's price for the year, minus the rebate, against what the same year costs elsewhere without one. Do that math with the actual quotes before you pay.

When is a year supply worth it?

• Your prescription covers the year. Under the federal Contact Lens Rule, a contact lens prescription generally lasts at least one year, unless your eye doctor sets a shorter date for a medical reason. Buy right after your exam, not in month eleven.
• You already know the lens works for you. A year of a lens you have worn for a while is a safer buy than a year of one you just started.
• A rebate applies and you will actually file it. The rebate only counts if you submit it within the deadline.
• You have FSA money to use. See the section below.

When is it not worth it?

• Your prescription expires before the boxes run out. Leftover boxes in an old power may not be right for your eyes.
• Your prescription or lens is likely to change. Ask the office what happens to unopened boxes if it does, before you pay.
• The up-front cost is a strain. The whole year gets charged today. The rebate shows up weeks later.
• You don't wear lenses every day. Part-time daily wearers go through fewer lenses, so a year's worth of boxes lasts longer than a year and may outlast the prescription.

Can you pay for a year supply with FSA money?

Usually, yes. Prescription contact lenses generally count as an eligible medical expense for FSA and HSA money, though your plan sets the rules. How that works is in can you use FSA or HSA for contacts.

This is where a year supply often makes the most sense. For plan years starting in 2026, you can put up to $3,400 in a health FSA. The money is use-it-or-lose-it, unless your employer's plan allows a carryover (up to $680 for 2026) or a grace period. If you have a balance left near the end of your plan year, a year of lenses is a common way to use it.

One catch applies if you also take a rebate. CooperVision's terms say that a claim you file with an insurer or employer plan must be based on what you paid minus the rebate.
