BY BASE CURVE

Contact Lenses by Base Curve – Find the Right Fit for Your Eyes

When choosing contact lenses, base curve (BC) is one of the most important factors for ensuring comfort, clear vision, and long-term wearability. At KPOP2, we help you shop Korean contact lenses by base curve, so you can find a lens that fits your eye shape perfectly and feels great all day.

Our collection includes 100% authentic Korean contact lenses, made by leading brands such as LENSTOWN, OLENS, I-SHA, Secriss, and more—designed to fit a variety of eye curvatures and styles, from natural to dramatic.

👁 What Is Base Curve (BC)?

The base curve is a measurement (in millimeters) that describes the curvature of the back surface of a contact lens. It must align properly with the natural curve of your eye’s cornea to:

• ✅ Ensure lens stability

• ✅ Reduce discomfort or shifting

• ✅ Prevent dryness or blurriness

• ✅ Support all-day comfort and oxygen flow

Most soft Korean contact lenses fall between 8.4 mm to 8.8 mm in base curve, with 8.6 mm being the most common universal fit.

🔍 Shop by Base Curve – What to Expect

We’ve categorized our lenses by base curve so you can easily find the perfect match. Here’s how each category works:

🔹 BC 8.4 – Tighter Fit for Smaller or Flatter Eyes

Base Curve 8.4 lenses are designed for users with:

• Smaller corneal radius

• Flatter eye curvature

• Preference for snug-fitting lenses

Best for:

• First-time users who need more stability

• Occasional lens wearers (shorter durations)

• Users who’ve had issues with lenses shifting

Popular 8.4 BC Products:

• Secriss 1Day Natural Series

• Some OLENS 1Day lenses

• Selected I-SHA Monthly Designs

🔹 BC 8.6 – The Most Common, Universal Fit

Base Curve 8.6 is the most widely used curve in Korean lenses. Designed to fit a broad range of users comfortably, it's ideal for most eye shapes.

Best for:

• Average corneal curvature

• Daily and monthly wearers

• Long-duration use (6–12 hours)

Popular 8.6 BC Products:

• LENSTOWN Romantea Bubbly, Roseberry

🔹 BC 8.7–8.8 – Looser Fit for Steeper Eyes

Some Korean lenses are available with a base curve of 8.7–8.8 mm, which is better for users with:

• Larger or more rounded corneas

• A history of tight lens discomfort

• Preference for slightly looser movement

Best for:

• Long-time lens wearers with high sensitivity

• People needing enhanced oxygen flow

• Special occasion users with dry eyes

Popular 8.7–8.8 BC Products:

• LENSTOWN Lighly Series (Luna, Pastel)

• Romantea Misty or Candy Series

• Selected silicone hydrogel designs

🛡 How to Choose the Right Base Curve?

If you're unsure of your base curve, we recommend:

• Checking your past contact lens prescription (BC is always listed)

• Visiting an optometrist for a corneal topography

• Starting with 8.6 mm if you're a new user with no known issues

A base curve that's too flat can cause the lens to slide around; too tight and it may feel uncomfortable or dry. The right curve will feel secure, clear, and unnoticeable during wear.

🌈 What Else Affects Fit?

Base curve is essential—but comfort also depends on:

• Lens material: Silicone hydrogel or HEMA

• Water content: 38%–58% depending on hydration needs

• Diameter: Graphic and overall lens size

• Edge design: Slim-edge technology for smooth blinking

We include full lens specifications on every product page to help you choose with confidence.
