Contact Lenses Contact lenses are a popular alternative to the wearing of spectacles, and are now worn by 8% of those requiring an optical correction. Contact Lenses are worn in the main by the younger generation in the 18 to 40 age group for cosmetic purposes, and those who actively participate in sport, however Contact Lenses are now becoming increasingly more popular with those in the 40 plus age groups who desire the freedom from wearing spectacles frames. Contact Lenses are virtually invisible whilst being worn as they effectively sit on a thin layer of tear covering the cornea. Because of the fact that they sit so close the surface of the eye they offer the wearer a much wider field of vision than do conventional spectacles because the contact lenses remain central to the filed of vision as the eye moves around and for many people this benefit alone is virtually a dream come true. Contact lenses fall into two main categories: Firstly -

It is important that you take the advise of the Contact Lens Practitioner when choosing Soft Contact Lenses because of the many different hygiene and cleaning regimes involved. It would for example not be advisable to try to extend the use of “Daily disposable” Lenses beyond 24 hours as they are not suitable for any kind of cleaning routines, similarly monthly and Quarterly Disposable should not be used beyond these periods as they are not designed to be durable or stable beyond these periods. The temptations may be great, but Contact Lens practitioners regularly see the results of Patients who have tried to “cheat the system” who present themselves to the practice with sore and red eyes. There are now also many new types of “Cosmetic” Contact lenses which can be used to change the colour of the eye, or indeed for those of you who may be so inclined you can change the appearance of the eye to make them look like “cats” eyes, or even “happy face” eyes. These types of lenses are designed for casual wear and it is strongly advised to adhere to the very strict storage and cleaning regime with these lenses, as they are not usually recommended for daily use. In all instances of Contact Lens wear it is “highly recommended” that the wearer stick to the hygiene and cleaning routine recommended by the Contact Lens Practitioner, and follow any advise given as to when to revisit for follow up checks as these visits can give the practitioner early warning of any impending problems related to wearing and the usage of the lenses.
