How to Choose the Right Colored Contact Lenses for Your Prescription

Quick Answer

To choose the right colored contacts for your prescription, first check if your prescription is for myopia (negative power) or astigmatism (with cylinder). For myopia, select lenses with your required power; for astigmatism, you may need toric lenses. Always verify the base curve and diameter match your eye's measurements, and choose a wearing schedule that fits your lifestyle.

If you wear glasses or clear contacts, you might wonder if colored contacts can work for your prescription. The good news is that many colored lenses are available with optical power, so you can correct your vision while changing your eye color. However, not all colored contacts are suitable for every prescription, and making the right choice involves more than just picking a shade.

This guide walks you through the key factors to consider, from understanding your prescription to matching lens parameters. We'll also highlight specific products that offer prescription options, so you can make an informed decision.

Understand Your Prescription

Your contact lens prescription includes several numbers: sphere (SPH) indicates the amount of myopia (negative) or hyperopia (positive), cylinder (CYL) and axis correct astigmatism, and base curve (BC) and diameter (DIA) ensure the lens fits your eye. While you may know your glasses prescription, contact lens prescriptions differ because the lens sits directly on the eye. Always use your current contact lens prescription, not your glasses prescription, when ordering.

For colored contacts, the most common prescriptions are for myopia (negative sphere values). If you have astigmatism, you'll need toric lenses that have a cylinder and axis. However, many colored contact lenses are spherical and do not correct astigmatism. In that case, you may need to consider other options or consult your eye care professional.

• Check the power (sphere) on your prescription: negative values correct myopia, positive values correct hyperopia.
• If you have astigmatism, look for lenses labeled 'toric' or with a cylinder and axis on the box.
• Always have a recent eye exam to ensure your prescription is up to date.

Lens Parameters: Base Curve and Diameter

Base curve (BC) and diameter (DIA) are critical for comfort and safety. The base curve should match the curvature of your cornea; a poor match can cause the lens to move too much or too little, leading to discomfort or blurred vision. The diameter affects how the lens covers your eye and how the colored portion appears.

For example, the Scotch Brown colored contacts have a base curve of 8.6mm and a total diameter of 14.2mm, which is a common size for many wearers. Similarly, the Romantea London 1Day Olive Green has a base curve of 8.6mm and a total diameter of 14.5mm, offering a slightly larger fit. Always compare these numbers to your prescription to ensure a proper fit.

• Your eye care professional can provide your exact base curve and diameter from a contact lens fitting.
• If your prescription doesn't list BC and DIA, ask for them; they are essential for ordering.
• Lenses with a larger graphic diameter may give a more dramatic color change, but ensure the total diameter is within your eye's tolerance.

Wearing Schedule and Lifestyle

Colored contacts come in daily, monthly, and yearly disposables. Daily disposables are convenient and hygienic, as you use a fresh pair each day. Monthly lenses require cleaning and storage but can be more cost-effective. Consider your lifestyle: if you wear contacts occasionally, dailies might be best; if you wear them daily, monthly lenses could save money.

For instance, the 247 Fit Brown daily lenses offer a 10-pack, perfect for occasional wear or trying out a new look. On the other hand, if you prefer a monthly option, the Scotch Brown monthly lenses come in a 2-pack and require proper care. Think about how often you'll wear them and your comfort with lens maintenance.

• Daily lenses are ideal for those with allergies or who prefer no cleaning routine.
• Monthly lenses are more economical for regular wear but require diligent cleaning and storage.
• Always follow the replacement schedule to avoid eye infections.

Decision Rules for Choosing Prescription Colored Contacts

• Check your prescription type: If your prescription is only for myopia (negative sphere), you have a wide range of colored contacts to choose from. If you have astigmatism (cylinder and axis), you need toric lenses, which are less common in colored options. Know your prescription before browsing.
• Match base curve and diameter: Compare the base curve and diameter on the lens box to your prescription. A mismatch can cause discomfort or poor vision. If unsure, ask your eye care professional. Use your exact BC and DIA for a proper fit.
• Select a wearing schedule that fits your routine: Daily lenses are convenient and hygienic; monthly lenses are cost-effective but require cleaning. Choose based on how often you plan to wear them and your comfort with lens care. Dailies for occasional wear, monthlies for regular wear.
