Learn how to order Velvet Grey prescription colored contacts with the right power. Follow a simple step-by-step process to read your prescription and pick the correct option.

Quick answer

Choose the power that matches your current contact lens prescription exactly, including any astigmatism correction if available. For Velvet Grey, select the option that corresponds to your spherical power, and choose 0.00 if you need no vision correction.

Why your prescription matters for colored contacts

Colored contacts with prescription are medical devices, so the power must match your eye exactly. Wearing the wrong power can cause blurry vision, headaches, and eye strain. Even if you only want a subtle color change, never guess your power or use an old prescription without verifying it with your eye care professional.

Reading your prescription for contact lenses

Your contact lens prescription includes numbers like -2.50 or -4.00 for spherical power, and sometimes values for cylinder and axis if you have astigmatism. Velvet Grey lenses are available in powers from 0.00 to -8.00, so check that your prescription falls within this range. If you have astigmatism, note that these lenses may not correct it; consult your eye doctor about whether they are suitable for you.

Steps to choose your Velvet Grey power

Get a current contact lens prescription: Visit your eye care professional for a contact lens exam and obtain a prescription specifically for contact lenses, not glasses. Prescriptions are typically valid for one year. Never use a glasses prescription to order contacts; the numbers are not interchangeable.
Locate the spherical power (SPH) on your prescription: Find the number labeled SPH, usually written as a negative value like -2.50. This is the main power you will select when ordering. If your prescription includes cylinder (CYL) or axis, these lenses do not correct astigmatism, so consult your eye doctor before ordering.
Check that your power is within the available range: Velvet Grey lenses come in powers from 0.00 to -8.00. If your SPH is outside this range, you cannot order this lens. If your power is -8.00 or higher (more negative), look for a different lens with a wider range.
Select the matching power option on the product page: Choose the option that exactly matches your SPH value. If you do not need vision correction, select 0.00. Double-check that you selected the correct eye (right vs. left) if the option is separate; many lenses are sold as a pair with the same power for both eyes.
Verify your order before checkout: Review the power in your cart to ensure it matches your prescription. Contact lens sellers typically cannot accept returns on opened boxes for hygiene reasons. Keep a copy of your prescription handy for future orders and reference.
