Frequently Asked Questions

Can Precision 7 for astigmatism be worn overnight?

Yes, Precision 7 for astigmatism is designed for both daily and extended wear of up to 6 nights. However, it is strongly advised that you never sleep in your contacts, as this increases the risk of infections, dry eyes and other eye health problems. If you wish to wear these lenses overnight, consult your optician first.

What is PRECISION BALANCE 8|4® lens design?

The PRECISION BALANCE 8|4® is Alcon's patented toric contact lens design that features two stabilisation points at the 8 and 4 o'clock positions, rather than just one. These points work with the eyelids to keep the lens stable, reduce rotation and ensure clear, consistent vision for astigmatism. The design balances against the lower lid, enabling a wider optic zone and improved oxygen flow.
