To provide our customers with the best care and service, we have implemented a verification system that complies with the Fairness to Contact Lens Consumer Law (FCLCA) and Rules for US customers. Under the FCLCA, we are required to verify your contact lens prescription.
We provide easy methods of verifying your contact lens prescription during your checkout process. The most efficient way is to upload your valid copy of the prescription. If you do not have it, we can verify your prescription directly with your eye care professionals.
1. Upload your copy of the prescription.
You can provide us with a copy of your valid prescription written by eye care professionals. You can either scan or snap a picture of your written prescription. Once the prescription is uploaded, we will keep the record for you, you can check out anytime without the need to re-upload again. Providing invalid or inaccurate prescriptions may result in order cancellation.
2. Submit the contact info of your eye care professional / optometrist/optician.
Kindly provide us with the necessary information, name, and phone number of your eye care professional.
We will contact your eye care professional and verify the accuracy of the prescription. Your eye care professional has eight business hours to respond (extended to the immediate working day upon weekends or public holidays). If your eye care professional does not respond within the required time, the prescription is verified automatically, and we may process and ship your order.
How to Read Rx
OD: OD stands for oculus dexter, the Latin phrase for “right eye.”
OS: OS stands for oculus sinister, the Latin phrase for “left eye.”
If both the left and right eye has the same diagnosis and prescription information, the abbreviation “OU” is used instead, or “ocular uniter,” meaning both eyes.
Sphere (SPH): This indicates the amount of lens power, measured in diopters (D), prescribed to correct myopia (nearsightedness) or hyperopia (farsightedness). The spherical power of a lens is indicated with a plus sign (+) for hyperopia and a minus sign (-) for myopia. Esoeye only supplies Myopia lenses at the moment.
Cylinder (CYL): This indicates the amount of lens power for astigmatism. If no cylinder power is noted, either you’ve no astigmatism or your astigmatism is so slight that it is not necessary to correct it with your eyeglass or lenses.
Axis: This describes the degree and direction of your astigmatism. The axis is a figure which determines the angle of the correction needed to see clearly, measured in degrees from 1 to 180.
Base Curve (BC): The base curve determines what type of fit is required for the lens to meet the curve of your eye. This is usually written in millimeters or sometimes with the words: flat, median, or steep.
Diameter (DIA): The diameter of a lens determines what length or width best fits your eye. It measures the width of a lens in millimeters, from end to end.
