Will my sight worsen if I start wearing specs or contact lenses?
Wearing a prescription does not make your vision worse. Often when someone gets spectacles for the first time the visual improvement is so amazing that vision without them seems much worse, especially as time goes by. However, this is simply because the brain can now compare two images directly: one with specs and one without.
 
What is the difference between a squint and astigmatism?
A squint is when one eye is turned either up, down, in or out relative to the other eye. The term 'lazy eye' is sometimes used when the turn is not detected at an early age and left uncorrected. It is essential that any parents noting a turn in their child's eye have them assessed by an Optometrist or eye doctor as soon as possible. The sooner it is treated the better the prognosis for use of this eye in later years. By the time the child has reached 9 years of age, it may already be too late.

Squints are sometimes confused with Astigmatism. Astigmatism is a condition where the shape of the eye is like an egg, whilst a squint refers to a turn in the eye. See Sight Conditions for more information on Astigmatism.
 
I feel odd in my new spectacles even though they are made to the same prescription as my old ones -
A change in your prescription is not all that causes a new pair of specs to feel weird. The frame change requires adaptation as you may be looking through a smaller or larger viewing area and the lenses may be closer or farther from your eyes compared with before. The lenses may also be tilted at a different angle in the new frame and perhaps the frame does not wrap your face as much or as little as it did previously. The type of lens design in the new specs will also influence your vision. For example, thinner, flatter, aspheric high index lenses often seem less clear when looking through the extreme periphery of the lens. Perhaps the centers of the lenses are higher or lower than before. This can also influence your initial comfort. Perseverance is the key to adaptation, but after 3 weeks without improvement, please see our spectacle collections team for further assistance.
 
How long will the eye exam take?
This should not take longer than 30 minutes assuming no extra tests or contact lens fittings are required. We endeavourer to have completed our service to you within an hour.
 
Can my contact lenses get 'lost' behind my eyeball?
No, this can NEVER happen as the eyeball has a 'safety net' situated underneath both eyelids. This 'safety net' is a membrane called the conjunctiva. The conjunctiva is a continuous membrane enveloping the outer portion of the eyeball as well.

Term Definition
GlaucomaThere are two types of adult-onset glaucoma and both refer to an increased abnormal pressure within the eyeball. The rarer form is when an acute attack occurs. Symptoms include a painful, red eye and possible light sensitivity and nausea. The most common form of Glaucoma is the preventable chronic type. Sight is adversely affected if it is not picked up early, the long-term effect being progressively worsening tunnel vision. It is essential to have your eyes screened for glaucoma once you are over the age of 40 years as the relative risk increases from this point. Other factors increasing the risk of glaucoma are diabetes, high levels of short-sightedness, age and family history.
