There are many different types of contact lenses available some of which may be suitable for you, read on to find out more about these different contact lenses and watch this short animation at the right to look at the advantages of contact lens wear.
Soft Contact Lenses
Soft contact lenses are the most common form of contact lens wear. They are a soft material that can transmit oxygen through the lens to your eye. Soft lenses are most commonly prescribed after a fitting process where a particular size and prescription is fit to you. You can also have customisable soft contact lenses for more complex prescriptions or if you need a particular cosmetic tint.
Soft contact lenses offer the following advantages:
- Quick adaptation to wearing
- Flexible wearing times
- Correction of most vision problems
- Simple and easy care & hygiene
- Ability to change or enhance eye colour
Soft contact lenses are also available as conventional lenses which usually last for 12 to 18 months using a care system which usually consists of separate solutions for cleaning, rinsing, disinfection & storage. More commonly they available as disposable soft lenses, daily-disposable lenses and as tinted soft lenses.
Rigid, or hard, contact lenses are less comfortable initially but do offer specific advantages for some eye and vision problems:
- Able to correct some conditions which cannot be treated with soft lenses.
- More durable and longer life.
- Often provide superior optics/ vision for more complex prescriptions
- Have a wider range of prescriptions correctable
- Highly customisable and made to measure
- Able to correct irregular corneas in cases such as keratoconus, pellucid marginal degeneration, post corneal graft and other conditions.
Hybrid lenses combine the comfort of soft lenses with the advanced optics of rigid lenses. These work well for patients with corneal astigmatism, some irregular corneas and for people looking for less aberration and more comfort. How they work is there is a central rigid lens with a soft lens “skirt”. The soft component sits on the conjunctiva (the film over the white part of your eye) whilst the hard lens sits on your tears to provide the vision correction.
These are fit to the parameters of the patients eyes. We use the Synergeyes range of hybrid contact lenses
Dr Boneham can advise which lens would be most suitable for you, we carry a wide range of trial lenses in the practice so can demonstrate the options during your consultation.
Some tips for contact lens wear
Contact lens Polishing
Another service we offer at Boneham Optometrist is our CL polishing for semi permeable Rigid Contact lenses, this is useful when the contacts are getting worn out and need a freshening up, very few optometrists around can offer this and we pride ourselves on our ability to provide this service. Sometimes protein can build up on the surface of your contact lenses and they require a professional clean, we provide this service in house
Wear and Care of your Rigid Contact Lenses
Disposable Contact Lenses
Disposable contact lenses are a sub-group within soft contact lenses. They provide improved eye health by the planned replacement of lenses before problems with lens aging and deposits can develop. These lenses have been made possible by improved methods of production which have lowered the cost to a point where disposability is affordable.
Different types of disposable contact lenses are replaced on a schedule of 1 week, 2 weeks, 1 month or 3 months.
Since the lenses do not have to last so long, the care and cleaning procedures are much simpler and are usually based upon a convenient 1-bottle system for cleaning, disinfection & storage.
Daily Disposable Contact Lenses
Disposable contact lenses have now progressed to the ultimate in disposability: Daily-disposables. These are worn once and discarded. There are no solutions required since the lenses never need to be stored.
Tinted & Coloured Contact Lenses
Soft contact lenses are also available in tints and colours. These fall in to 3 main categories:
VISIBILITY TINTS to make it easier to see and handle the contact lenses. These are usually a pale blue and included in the lenses at no extra charge
TRANSPARENT TINTS which are used to work with and enhance the patient’s own natural eye colour. For example: to make a hazel eye greener
COSMETIC TINTS which are used to cover and completely change the patients own eye colour. For example: to make brown eyes blue.
