Modes of Contact Lens Wear 
 

Daily Disposable Contact Lenses 

Care

Daily disposable lenses are designed to be inserted in the morning, worn for the rest of the day, and then removed and discarded in the evening

Lifestyle

Single-use lenses are best suited to those who live a busy lifestyle and demand minimal maintainence. These lenses are the most comfortable and hygienic.

2 Weekly Disposable Contact Lenses

Care

Clean lenses daily by rubbing the lens and soaking the lens in a multipurpose disinfecting solution to maintain hygienic lenses.

Lifestyle

Two weekly disposable contact lenses are worn for a period of two weeks. The lenses require nightly disinfection before being reworn the following morning.

Monthly Disposable Contact Lenses

Care

Monthly disposable contact lenses are easy to care for with cleaning and disinfecting performed nightly allowing the lens to be re-used for a full month.

Lifestyle

Monthly contact lenses are designed to be worn for 30 days. As the lens is kept for a longer period of time, particular care is required to keep the lens clean.

Semi-Permanent Contact Lenses
 
Soft Contact Lenses
 
Care
Soft contact lenses are designed to be worn for up to 18 months before needing replacement. Generally, these lenses do not provide as much oxygen to the cornea as some of the other more modern lens types, although newer more breathable lens materials have become available in recent years. Soft contact lenses can be worn for about 10 hour per day and 6 days per week.
 
Lifestyle
Soft semi-permanent lenses are often selected as a comfortable option for those with high and unique prescriptions. As the lens is more prone to contamination and lens deposit buildup, particular care is required in maitaining these lenses, including using specific cleaners and protein removing products. These lenses are best suited to those who have limited options available in disposable lenses but still demand soft lens comfort.
 
 
Rigid Gas Permable (RGP) Contact Lenses
 
Care
Rigid gas permable (RGP) lenses are designed to be worn up to 2 years before needing replacement. These lenses are very healthy and provide high levels of oxygen to the cornea. RGP lenses are relatively simple to look after, requiring a multipurpose solution and protein removing enzyme treatment periodically.
 
Lifestyle
RGP contact lenses are often selected for those who demand the sharpest vision, those with irregular corneal shapes and high prescriptions and are great for dry eye and allergy sufferers. RGP lenses may be worn full-time during the day, and just removed for sleeping overnight, although in the case of OrthoKeratology the lenses are worn overnight instead of daytime.
Contact Lens Designs
 
Contact-Lens-AstigmatismToric Contact Lenses Toric contact lenses are specifically designed to correct astigmatism present in the eye and provide sharp vision. Contact lenses that correct for astigmatism are designed to focus light in two different orientations so they are designed to maintain their orientation whilst on the eye. This is usually done by thickening or 'weighting' strategic portions of the lens to minimise lens rotation even whilst the eye is moving and blinking. Toric contact lenses are available in all types of disposable lenses, soft semi-permanent lenses and rigid gas permeable (RGP) lenses.
Contact-Lens-MultifocalMultifocal Contact Lenses Multifocal contact lenses are designed to correct both near and far vision simultaneously, much like progressive lenses in glasses do. Contact lenses that work as multifocals are designed to focus near vision within a specific 'ring' of the contact lens, whilst distance vision is focussed in a different 'ring' of the lens. These 'rings' of clear vision are blended to provide a natural and smooth transition between distance and near targets. Multifocal contact lenses are available in all types of disposable lenses, soft semi-permanent lenses and rigid gas permeable (RGP) lenses.
 
contact-lens-orthoK
Orthokeratology Contact Lenses Orthokeratology contact lenses are worn overnight and designed to gently reshape the cornea to correct for myopia (short-sighted). These lenses are removed from the eye in the morning and provide clear vision for the rest of the day without the need for additional contact lenses or glasses.
