Is there a big difference between 8.6 and 8.8 base curve?
A base curve of 8.6 mm of radius is more curved, and therefore a tighter fit, compared to the 8.8 mm base curve. People who have steeper corneas require tighter fitting contacts. If a contact is too loose, it may be uncomfortable, fold, or come right out.

Why are my new contacts blurry?
Some blurriness is common for new contact lens wearers. The distortion usually results from dryness. To counteract the moisture loss, talk to your eye care practitioner about medicated eye drops or pick up over-the-counter drops from your favourite drugstore. Do not drive or bike while experiencing blurry vision.
What’s the difference between 8.4 and 8.8 base curve?
The 8.4mm base curve is still the likely best fit for the majority of eyes. In instances when the 8.4mm lens is too steep, the 8.8mm lens allows a flatter option. This is more likely needed in smaller eyes, and possibly in some very flat corneas.
