Does base curve and diameter matter for contacts?
The diameter and base curve are important factors in determining what the optimum fit is for you. A proper fit ensures full coverage of the cornea, optimum edge alignment, and adequate movement of the lens for tear exchange.
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.
What is the difference between Acuvue Oasys and Acuvue Vita?
What is the difference between Acuvue Oasys and Acuvue Vita? The difference between Acuvue Oasys and Vita is the replacement schedule.

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.
