How to Read Your Prescription and Order the Correct Contact Lenses on MocoQueen
Posted by Mocoqueen on 7th Aug 2025
? Step 1: Make Sure You Have a Valid Contact Lens Prescription
-
Your prescription is for contact lenses (not glasses).
-
It includes details for both eyes.
-
It clearly lists information like Power (SPH), BC (Base Curve), and DIA (Diameter).
-
It is not expired. In the U.S., most prescriptions are valid for 1–2 years.
? Please note: Whether you're ordering prescription or non-prescription lenses, a valid contact lens prescription is required.
?️ Step 2: Check if Our Lenses Are Suitable for Your Prescription
-
Prescription lenses (marked with “Rx” on the product page)
-
Non-prescription lenses (no “Rx” marking)
-
SPH (Sphere/Power)
-
DIA (Diameter)
-
BC (Base Curve): The curvature of the lens. Slight differences (±0.2) are generally acceptable, but consult your doctor if unsure.
? For customers with mild astigmatism or farsightedness: You may ask your eye care provider whether it's safe for you to wear non-prescription lenses for short periods for cosmetic use only.
? Step 3: Select Your Prescription Based on Each Eye
-
If both eyes have the same prescription:
-
➤ Select your left eye (OS) power based on your prescription.
-
➤ Then choose “Same as Power (L)” for your right eye (OD).
-
-
If your eyes have different prescriptions:
-
➤ Select your left eye (OS) power.
-
➤ Then choose your right eye (OD) power using the “-XXX (Add $3.99)” option.
-
? Important Note: Our prescription lenses increase in -0.50 increments only (e.g., -1.00, -1.50, -2.00). If your prescription includes -0.25 values (e.g., -1.25), we recommend choosing the closest lower option (e.g., -1.00). Choosing a higher power than needed may lead to discomfort or blurry vision.? Inventory Tip: Our inventory is based on your left eye (OS) selection. If your left eye power is available, your order is in stock. If the left eye power is not available, the product is out of stock—even if the right eye option is selectable.
? Step 4: Uploading Your Prescription for Verification (U.S. Customers)
-
Our verification team will carefully review your prescription.
-
If there’s any issue or missing information, we’ll reach out to you before shipping.
-
If everything looks good, your order will proceed normally—you do not need to wait for a confirmation from us to complete your purchase.
