Pure Vision Multi-focal
Contacts Pure Vision Multi-focal are an alternative to bifocal and progressive eyeglasses. Multifocal contact lenses, like lenses of ordinary eyeglasses, have several zones of different optical power and can be used to see clearly both close and distant objects.
At the bottom of this contact lens there is a zone for near vision and at the top – for distant. There is also a boundary between them. Always when you look into the distance you use the upper zone and when you read or work at a close distance – the lower. Lenses must fit on eyes reliably and avoid displacements of optical zones. That is why the bottom of contact lenses Pure Vision Multi-focal has a small cut to prevent rotation while blinking.
Silicone-hydrogel material provides a high level of oxygen permeability, which helps to maintain a healthy eyesight and at the same time it prevents the surface of the lens from the accumulation of protein deposits. Lenses PureVision Multi-Focal are approved for use in day-time, flexible and continuous (uninterrupted) wearing regimens for up to 30 days after required consultation with the professional ophthalmologist.
