Purevision Contact Lenses

PureVision2 are monthly silicone hydrogel contact lenses from Bausch + Lomb, combining high oxygen transmissibility with High Definition Optics to reduce common visual aberrations such as halos and glare, particularly in low-light conditions. Made from a silicone hydrogel material, PureVision2 allows significantly more oxygen to reach the eye than standard hydrogel monthly contact lenses. The range includes sphere, PureVision2 for Astigmatism, and PureVision2 for Presbyopia variants.

Yes, but only under your optician's guidance. PureVision2 contact lenses are approved for extended wear of up to 29 nights and 30 days, but suitability for overnight wear depends on individual eye health and tear film quality. Your optician will assess whether your eyes can safely tolerate reduced overnight oxygen supply before recommending extended wear. Most eye care professionals recommend removing your lenses at least once a week to give your eyes a rest, even if extended wear has been approved.

High Definition Optics is the lens design feature in PureVision2 that minimises spherical aberration, a common optical imperfection that causes halos, glare, and reduced contrast, particularly when driving at night or in low-light conditions. The design controls how light rays converge at the retina across the full lens diameter, creating a more precise focal point. Wearers who have noticed haloes around lights or soft visual quality with other monthly contact lenses often find PureVision2's optical design provides a noticeable improvement.

PureVision2 silicone hydrogel contact lenses support healthy oxygen supply to the eye, which helps maintain the corneal surface and can reduce some lens-related dryness. However, PureVision2 does not use a dedicated moisture-retention technology as other lenses do If dry eyes are a significant concern, your optician may recommend one of those alternatives, or suggest pairing PureVision2 with a compatible lubricating eye drop during wear.

PureVision was Bausch + Lomb's original monthly silicone hydrogel contact lens, launched in 2002 with AerGel material  for high oxygen permeability. PureVision2 is the updated generation, adding High Definition Optics to reduce visual aberrations alongside the silicone hydrogel material. For wearers who notice halos, glare, or reduced sharpness with standard monthly contact lenses, PureVision2's optical improvements deliver a measurable upgrade in visual clarity.
