Period of use
Daily contacts are far and away the most popular type. Wear them by day and take them out at night. Depending on the replacement period, you then clean them and put them to bed for the night or just throw them away.
Much less common are extended wear contacts. These you can wear continuously up to 7 days in a row, day and night. They’re not for everyone and require close followup by an eye care professional.
Soft, rigid, and hybrid contact lenses
Contact lenses are made of a variety of materials and are divided into 3 main categories: soft, rigid and hybrid.
Soft contact lenses
Soft contact lenses are made of hydrogel or silicon hydrogel. The thin, pliable lens conforms to the shape of your eye and lets plenty of oxygen through. They’re ideal for intermittent use, require a short adaptation period, and are ideal for active wearers because they rarely fall out. Soft contacts are currently the most popular type of contact lens.
Rigid contact lenses (RGP)
RGP stands for Rigid Gas Permeable. These are contacts that retain their shape after you put them in. The result is clear vision, and they’ll correct most cases of corneal astigmatism. Generally they take a bit longer to get used to than soft contacts. They’re made of oxygen-permeable materials and are often recommended to patients with dry eyes or those who for a particular reason can’t wear soft contacts.
Hybrid contact lenses
Hybrid or semirigid contacts are made up of a rigid central section with hydrogel or silicon hydrogel all around it.
To find out more about the materials your contact lenses are made of, or discuss what would work best for you, talk to your Opto Réseau eye care professional.
As a rule, the shorter the replacement period, the higher the water content of the lens or the thinner it is in the centre. Being thinner in the centre generally makes a lens more comfortable because it can let more oxygen through.
Monthly and two-week replacement
If your optometrist prescribes contacts you have to take out and store, be very strict about cleaning and disinfecting them after every use. Some lenses in this group can be worn for longer periods, but most need to be cleaned and disinfected every day.
You also have to be very strict about the replacement deadlines your eye care professional recommends because, over time and even with regular maintenance, deposits of proteins and fats build up on your lenses.
Daily disposable lenses don’t need to be cleaned or stored, because you throw them away after use. They’re recommended for people with dry eyes, for occasional wearers, and travellers, as well as for anyone who just wants something comfortable and easy to use.
