Contact lenses are a great addition to glasses in providing clear vision for all activities. The majority of people are suitable to wear contact lenses, and there are lenses to suit all prescriptions. The type of contact lens your optometrist will recommend depends on your lifestyle, prescription and eye health.
Daily disposable soft lenses
These lenses suit flexible contact lens wearers who value convenience, hygiene and comfort. Each lens is worn for a single day and then replaced, so there is no fussy cleaning and storing of lenses. Wearing a fresh lens each time is the cleanest and most comfortable contact lens option. It is also very convenient for people who wear their lenses a few times a week, for example to go out for social events or sport.
Monthly replacement soft lenses
These lenses suit people who want to wear their lenses most days. The lenses are removed, cleaned and stored each night, and replaced after 2 or 4 weeks depending on the brand.
Extended (overnight) wear
Extended wear is when a soft contact lens is left in the eye overnight for a maximum of 4 weeks at a time (with a few exceptions). The latest silicone hydrogel materials have high oxygen transmission to enable this. Not every contact lens wearer is suitable to wear contact lenses overnight, so discuss this with your optometrist.
Contact Lenses for Astigmatism
Astigmatism in you glasses does not stop you from wearing contact lenses. Contacts are available in daily, 2 weekly, monthly and extended wear types. Hard Gas Permeable lenses are also an option to correct a large amount of astigmatism. Talk to one of our optometrist to discover what contact lens types are best for your prescription.
Multifocal Contact Lenses
Multifocal contact lenses correct both distance and reading vision in the same contact lens. This is ideal for anyone over 40 years of age who needs reading glasses. Multifocal contact lenses are also sometimes recommended to slow the progression of myopia (short-sightedness) in children and young adults.
Coloured Contact lenses
Coloured soft contact lenses are available to change the natural colour of your eyes, and can be worn even if you have no prescription. There is a wide array of colours available, from subtle shades to vibrant blues and greens. Some of the colours available include: Brilliant Blue, Sterling Grey, Gemstone Green, Caribbean Aqua and Honey.
Coloured contact lenses are not currently available for people with astigmatism or multifocal contact lenses, with a few exceptions.
Hard Gas Permeable Lenses
Hard Gas Permeable lenses are the ideal correction for patients with high amounts of astigmatism, corneal eye diseases and after corneal surgery. The materials used are highly oxygen permeable and these lenses are comfortable once the eyes initially adapt.
Orthokeratology (Ortho K) involves the gentle reshaping of the cornea in order to eliminate the need for glasses or regular contact lenses. Ortho K uses hard contact lenses that are worn overnight, which alter the shape of the cornea enough to provide the wearer with clear vision throughout the day. As the reshaping of the cornea is temporary, the lenses must be worn every night otherwise the effect is reversible. Initially it may take a few nights wear before good vision is achieved.
