RX Verification (Applies only to US customers)

What is it?

Marimonda Ltd’s number priority is providing top-notch customer service. As such, we’ve implemented a prescription verification system that is in compliance with the Fairness to Contact Lens Consumer Law (LCLCA).

In order to verify your prescription in the most efficient, convenient way possible, we can use one of two methods:

A) Upload your RX

You provide us with a valid copy (photo or scan) of your prescription, which you can upload either

  • When you create an account with us OR
  • When you add your item to your shopping bag.

Alternatively, you can email this file to support@turtlecontacts.com and include your order ID.

B) Submit your doctor’s name & phone number (easiest)

You submit your optometrist’s name and phone number, and we’ll call them to verify your prescription. This process takes 12 hours. Our initial phone call is meant to inform your optometrist’s office of your provided prescription, so that they can, at their convenience, verify it by calling us. The FCLCA requires that the contact lens vendor (Marimonda Ltd’s) must wait for at least 8 hours after the call before shipping anything. If the vendor (Marimonda Ltd’s) does not receive a response from the optometrist within this time frame, the vendor is allowed to process and ship the order.

What if I don’t have a contact lens prescription? You can get an online eye exam with a contact lens prescription from the comfort of your own home. The service is offered by Opternative and costs US$40. After you receive the prescription, please send it to us either with the upload form when you place your order or via email (support@turtleco.com).

How to Read Your Prescription

Looking at your prescription for eyeglasses, you will see two headings labelled

  • OD: Latin oculus dexter, meaning “right eye
  • OS: Latin oculus sinister, meaning “left eye

If you have a heading labelled “OU,” which is Latin for oculus uterque, it pertains to “both eyes.”

Other headings that your eyeglass prescription may have include

  • SPH (Sphere): The number indicates the diopter (abbreviated as “D”) required to correct your vision. The farther it is from 0, the more vision correction you need. A minus sign (-) in front of the number indicates myopia (i.e. you are nearsightedness). A plus sign (+) in front of the number indicates hyperopia (i.e. you are farsightedness). Here at Marimonda Ltd’s we sell colored contacts that correct only myopia, not hyperopia.
  • CYL (Cylinder): This number indicates the diopter required to correct your astigmatism. It can have a minus (-) or plus (+) sign in front of it. The further it is from 0, the more astigmatism you have. If the cell is blank, it means your doctor has determined you don’t have or don’t need to correct your astigmatism.
  • Axis: This number ranges from 0 to 180 and shows the orientation of your astigmatism corresponding to the curvature of your eye. Please note that Cylinder and Axis numbers must exist together. Sometimes, the Axis value is separated from the Cylinder value by an “x” (especially in handwritten prescriptions).
