Contact Lens Fitting and Exam


Only once we have measured the shape and size of your eye, conducted a comprehensive examination of your overall eye health and discussed your lifestyle, habits and work, can we recommend lenses. The idea is that they fit not only your eye, but also that they seamlessly integrate into your day-to-day life. Of course, we will also re-evaluate your prescription at every exam.

Not all contact lenses were created equal. Depending on the outcome of your assessment, your optometrist Dr Armstrong may discuss the need for a speciality lens. These types of lenses are specialized to meet specific needs, and include:

Scleral lenses

These are larger-than-average lenses which are more stable on the eye, and are often prescribed to those for whom regular lenses are not an option.

Toric lenses

Designed specifically to correct astigmatism due to an irregular curvature of the cornea. They have no “normal” shape and are made to suit each pair of eyes.

Multifocal lenses

Multifocal lenses are, as the name suggests, lenses which offer multiple prescription within a single lens: one for short distance, one for long distance. These are very useful in helping those with presbyopia when their reading vision degrades with aging.

RGP lenses

These are often described as the most comfortable contact lenses. They transmit oxygen through to the eye, rather than being lubricated by water. These are custom-made to fit snugly onto your cornea.

A Typical Contact Lens Fitting and Exam

Our standard exam comes in 3 parts: evaluating eye health, assessing visual acuity and measuring properties of the eyeball.

Eye health

As with any eye exam, we use a range of technologies in order to fully understand your eye health. These technologies include Visual Field Screening (to measure the quality of your peripheral vision and consequently the existence of diseases like glaucoma) and Optomap Retinal Imaging to get a detailed look at your retina.

Visual Acuity

We employ common eye tests to assess your vision at varying distances, as well as the quality of your central and peripheral eyesight. This is doubly important as they can indicate underlying conditions, but also so that we can update your prescription if required.

Measuring the Eye

The exact shape of the cornea can vary from person to person, and by obtaining accurate dimensions for each eye, we can provide tailored lenses for improved comfort and vision.
