There are two main types of contact lenses: ‘hard’ and ‘soft’ lenses. The older style of hard lenses have now mostly been replaced by the rigid gas permeable (RGP) lenses, which are better for the health of the eye. They may be referred to as ‘hard’ lenses or as RGP lenses. Both hard and soft lenses have their own advantages and disadvantages for the wearer.
Rigid gas permeable lenses
RGP lenses have tiny holes in them to allow plenty of oxygen to reach the cornea (surface of the eye). This is important for the long-term health of your eyes. These lenses are more expensive than soft lenses but can last for years and provide a sharper vision. They are also less likely to trap bacteria than the soft lenses and are easier to care for, although they are harder to insert and take out. However, you need to slowly build up the time you spend wearing RGP lenses, so they are not suitable for occasional use. It can take up to 4 weeks to get used to wearing them.
Soft lenses are quick to get used to wearing, so can be used occasionally. They are flexible and have a high water content and are usually larger than RGP lenses, allowing easy removal and better retention in the eye. They are less likely to trap dust and eyelashes than hard lenses, although they can be easily damaged if not cared for properly, and may exacerbate dry eyes. Soft lenses come in a wide variety, including coloured, bifocal and disposable types.
Disposable or frequent replacement lenses
Disposable lenses are worn for a period of time then thrown away. Daily disposable lenses remove the need for cleaning products, although weekly or monthly disposable lenses require nightly cleaning. Protein build-up on the surface of the lenses is not usually a problem because they aren’t kept for more than a month.
Day and night lenses
Day and night lenses are designed for up to 30 days’ continuous use and are then thrown away. They are made from silicone hydrogel, which allows more oxygen to reach the cornea than standard soft lenses. This means the eye can breathe, even while you sleep.
‘Cosmetic’ soft lenses
Soft lenses can also be obtained in varieties for ‘cosmetic’, ‘special effect’ or ‘novelty’ lenses. These lenses may be opaque or tinted, in order to change eye colour or add designs. The middle of the lens is left clear to allow you to see. Your vision can be affected if the lens slips from its correct position.
Always check with an optometrist before using any type of cosmetic lens, as some people have eye conditions that make them unsuitable. Also follow instructions about length of wearing time and any cleaning of lenses or hygiene measures that may be required.
See Your Pharmacist or Medical Professional
- Before wearing lenses each day, check your eyes are comfortable, you can see clearly and your eyes are not red. Otherwise, seek professional healthcare advice, and do not wear the lenses until your eyes are back to normal
- If you develop a painful red eye while wearing lenses, take the lenses out and seek advice from your optometrist or doctor
- If contact lenses make your eyes drier than normal, ask your optometrist or pharmacist for advice on lubricant products that can be used with contact lenses (also see Treatment Options, below)
