What do I need to order glasses?

Make sure you have the following in front of you to order a pair of well-fitted glasses accurate to your prescription (Rx):

1. A copy of your glasses prescription, no more than 2 years old.

2. Your pupillary distance (PD) should be written on the prescription. If not, please use our PD Measurement Tool.

3. (Optional) A pair of glasses/sunglasses that already fit you well. Note the set of 3 numbers located on the temple (arm) or nose bridge of the frame. Use our Fit Calculator to find frames that will fit your measurements.

Glasses measurements is the set of 3 numbers printed on the temple or bridge of your frames

How do I read my prescription?

This is what a typical glasses Rx looks like:

  1. Sphere (SPH): +’ve value indicates hyperopia (farsightedness), -’ve indicates myopia (nearsightedness)
  2. Cylinder (CYL): having a value here indicates presence of astigmatism. It can be written with + or -. - is usually written by an optometrist, whereas + is usually written by an opthamologist. They both mean the same thing.
  3. Axis: having a value here indicates presence of astigmatism. Please note that 000 = 180 (they mean the same thing)
    Both CYL and AXIS are needed together (cannot have one without the other!)
  4. Add: This provides magnifying power for reading, progressive and bifocal lenses. You will have the same number for both eyes.
  5. PD: Pupillary Distance:

    Our Rx lab can process any single-vision Rx (which includes normal glasses for farsightedness/nearsightedness and readers) that fits in the following ranges: SPH -10.00 to +10.00, CYL 0.00 to -6.00

What is the PD? Where do I find mine?

Sometimes, your glasses prescription may not include your pupillary distance (PD), the distance between the centres of your pupils in millimetres. Your PD is absolutely mandatory when installing your prescription lenses for proper clarity and focus. If your PD isn't written on your prescription, it may be due to one of two reasons:

1. Your prescription is for contact lenses.

If this is the case, you'll see a contact lens brand on your prescription. The prescription here won't work for glasses, so you should go to your optometrist and request one. Alternatively, you can take an online eye exam on Opternative (not affiliated) from the comfort of your home.

2. Your optometrist/optician didn't give you one.

Optometrists usually omit the PD if they assume you're buying glasses from their shop (or for other motives). In this case, you can save the trip back and use our online PD tool.

Are MOONSPECS glasses covered by FSA or HSA?

Yes, since prescription eyeglasses are considered a medical expense, you can use your flexible spending (FSA) or health savings accounts (HSA) dollars at MOONSPECS.

Prescription eyeglasses (including readers), prescription lenses and prescription sunglasses are covered. FSA and HSA funds can be used regardless of whether you have vision insurance.

There is no limit on how many pairs of prescription glasses you can purchase with FSA/HSA dollars. You just need to know how much you have in fund savings.

HSA funds are accrued throughout the calendar year, with contributions from individuals (up to $3300/year) and sometimes employers, like with a 401(k). You need to be entrolled in a high-deductible plan (min. $1250) to be eligible for a HSA.

How do I use my FSA/HSA dollars to buy MOONSPECS eyewear?

Good news; you don't have to do anything special to buy prescription eyewear with FSA/HSA funds! If you have an FSA or HSA debit card, use it to check out, just like you would with a regular credit card. This saves you the hassle of having to submit a reimbursement form to your insurance provider.

If you don't have a FSA/HSA debit card, simply check out with a regular credit card, print out the order confirmation and submit it it to your FSA/HSA provider. Usually, you wll be required to submit a reimbursement form along with the itemized receipt (which is the order confirmation email).

When can I use my FSA/HSA dollars? When do they expire?


Generally, all of your FSA funds are available at the beginning of your coverage period, which is one calendar year starting Jan 1st. They usually expire by Dec 31st or Mar 15th. You may be eligible for carrying $500 of unused FSA funds from the previous year, or extending the expiry by 2.5 months, depending on your employer. FSA funds have a "Use it or lose it" policy - unused dollars will be lost once your coverage period is over.



HSA funds never expire. Any unused funds in your account roll over to the next year.



Can you accept insurance as payment?

MOONSPECS does not work directly with insurance providers at this time.

Depending on your provider and coverage plan, your MOONSPECS purchase may be eligible for reimbursement. We can provide you with an itemized receipt if needed. Please clarify the details with your insurer.


What are the payment options?

You can pay via Paypal, Visa, Mastercard and American Express. We are also big crypto supporters, so we accept Bitcoin, Ethereum, Bitcoin Cash and Litecoin as well.
