CONTACT LENSES ARE AN ALTERNATIVE TO GLASSES AND COME IN A VARIETY OF FORMS. A CONSULTATION WITH YOUR OPTOMETRIST WILL DETERMINE IF YOU ARE LIKELY TO BE A SUCCESSFUL CONTACT LENS WEARER AND WHAT TYPE OF LENSES WILL SUIT YOU BEST.
Some of the contact lens options include:
Daily Disposable Contact Lenses
These lenses are worn once and then disposed of. With daily replacement, these lenses provide maximum comfort and sterility. They also provide a very effective option for people who want to wear contact lenses occasionally.
Fortnightly/Monthly Disposable Lenses
These require disinfection between each use and are available in several different designs. These are more cost-effective for those who wish to wear lenses most days.
Extended Wear Contact Lenses
These are made from a special silicon hydrogel material that allows them to be worn overnight. They are currently available in 1, 2 and 4-week versions. The lenses must initially be assessed at the one-day, one-week and one-month stage to determine suitability.
Multifocal Contact Lenses
Available in a variety of different disposable lens designs. They allow for far and near vision at the same time. A frequently used alternative to multifocal contact lenses is
This is a system by which one eye is focussed for reading and the other is focussed for distance.
Custom-Made Contact Lenses
Made to last up to 1-2 years. Because of higher maintenance requirements, increasing allergy rates and dry eye issues, these lenses are now less frequently used.
Rigid Gas Permeable (RGP) lenses or Hard Contact Lenses
These are a lot more rigid in their structure. Although initially less comfortable than the soft lens designs, RGP lenses still have their place in specialised contact lens fittings for conditions such as keratoconus and are the lenses required for Ortho-Keratology.
Short Sightedness Treatment
Ortho-Keratology is a contact lens treatment for myopia (short sightedness) and low degrees of astigmatism. It involves wearing a rigid contact lens worn at night to re-shape the cornea so that glasses and contact lenses are not required during the day. Ortho-Keratology is adaptable to changing prescriptions and research shows this to be the most effective method of keeping short sighted progression at bay.

Keratoconus is a condition in which the cornea becomes thin and stretched, bulging outwards into a conical shape. This causes vision distortion and significant vision impairment if left without treatment. Thankfully, modern treatments allow individuals with keratoconus to live normal lives.
Graham Hill Eyecare provides treatment for keratoconus in Shepparton in the form of RGP contact lenses which can maintain the shape of the cornea. Jenni Sorraghan and Sao Tyler specialise in fitting these lenses.
