How to Choose Farsighted (+) Colored Contact Lens Prescriptions
👓➡️👁️ Farsighted? No Problem! How to Shop Your Prescription Online 🌈✨
Ready to level up your look with EyeCala colored contacts but have a farsighted (hyperopia) prescription? We got you! This guide makes it super simple to pick the perfect lenses online so you can see clearly and look iconic. 😊
1️⃣ Decoding Your Prescription (The "Plus" Sign Matters!) 📋🔍
If you are farsighted, your glasses prescription will have positive (+) numbers under the Sphere (SPH) column. Here's what that looks like:
| Eye 👁️ | Sphere (SPH) | Cylinder (CYL) | Axis (°) |
|---|---|---|---|
| Right (OD) | +2.50 | -0.50 | 90° |
| Left (OS) | +3.00 | - | - |
- ✅ Positive (+) Sphere: This means you are farsighted (hyperopia).
- ✅ Cylinder (CYL): This indicates astigmatism (usually a negative number).
The Astigmatism Rule: If your astigmatism (CYL) is mild (-0.75 or less), you can totally wear our regular spherical colored lenses comfortably!
⚠️ Heads Up: At EyeCala, we currently do not offer colored lenses that correct both farsightedness (+SPH) and astigmatism (CYL) at the same time. If your astigmatism is moderate or strong (above -0.75), please chat with your eye doctor before ordering to avoid blurry vision.
2️⃣ Picking the Right Power (The Math Part) 🎯
For farsightedness, your contact lens power is usually super close to your glasses prescription. Here is the cheat sheet:
- ✅ +0.25 to +4.00: Easy! Choose the exact same sphere power as your glasses.
- ✅ Above +4.00: You need a tiny adjustment. Check the chart below:
| Glasses SPH | Recommended Contacts SPH | Example |
|---|---|---|
| +4.25 to +5.00 | Add +0.25 | +4.50 glasses → +4.75 contacts |
| +5.25 to +6.00 | Add +0.50 | +5.75 glasses → +6.25 contacts |
| +6.25 to +7.00 | Add +0.75 | +6.50 glasses → +7.25 contacts |
| Above +7.00 | Consult your eye care professional | — |
📌 Pro Tip: If your exact number isn't listed in the dropdown menu, pick the nearest lower power. It's usually more comfortable for your eyes!
3️⃣ Base Curve (BC) & Diameter (DIA) 📏
Don't stress about these numbers too much unless you have very specific needs:
- ✅ Standard Base Curve (BC): 8.6mm (Fits most eyes comfortably)
- ✅ Standard Diameter (DIA): 14.0–14.5mm (The size of the lens)
✨ Unless you know for a fact that you need a custom fit, our standard EyeCala sizes are designed to fit the majority of users perfectly.
4️⃣ What About PD? 👀
Good news bestie! Pupillary Distance (PD) is only for glasses frames. You can completely ignore it when buying contacts. 🎉
📝 The "Add to Cart" Checklist:
- ✅ +0.25 to +4.00? Match your glasses prescription exactly.
- ✅ Over +4.00? Use the chart above to adjust slightly.
- ✅ Astigmatism? Only order if your CYL is -0.75 or less (since we don't have toric lenses for farsightedness yet).
- ✅ BC & DIA: Stick to the standard 8.6mm / 14.0-14.5mm.
👩⚕️ Final Vibe Check
Your eyes are precious! Always double-check your prescription. If you have a high prescription or strong astigmatism, it's always safer to ask your eye doctor first. If you're stuck, email our team at cs@EyeCala.com!
