What are night and day contact lenses?

Night and Day contact lenses are produced by CIBA Vision and represent a real alternative for anyone who wants clear round-the-clock vision, but may be reluctant to undergo laser eye surgery.

Night and Day contact lenses have been designed for up to 30 days continuous wear, before being disposed of and replaced with a fresh pair.

At a practical level this means no more of the ‘hassle' associated with standard contact lenses (including cleaning and daily fitting), which makes Night and Day are a popular choice for anyone with a busy schedule.

While laser eye surgery is an option for many people, it isn't suitable for every condition, it carries more potential complications, and it isn't within everybody's financial reach. If you are in any doubt about what's best for you, consult your eye-care professional.

Extended wear contact lenses aren't new to the marketplace, but Night and Day are the first soft lenses to be made with silicone hydrogel - a material which allows up to six times more oxygen to the cornea than standard lenses. This effectively means the eye can ‘breathe' (even while sleeping), which makes the lenses both more comfortable, and much less likely to irritate the eye.

Over the past decade the technology behind extended wear contact lenses has been revolutionised, and manufacturers are keen to let everyone know that things have moved on substantially. A good starting point for additional information, especially regarding safety issues, is the parent company website (in this case CIBA Vision), although they do not supply contact lenses directly to customers.

Night and Day contacts are suitable for both myopics and hypermyopics with astigmatism of up to approximately 1.5 dioptres. As with all contact lenses it's difficult to over stress the importance of regular follow up appointments with your eye-care professional; to establish the suitability of the prescription, the fit and the comfort of the lens, and to assess the general health of the eye.
