My close-up vision is not as good as it used to be - is this normal?
Yes - this change in your near vision focus happens to everyone and is called Presbyopia. The effect of presbyopia is similar to that of longsightedness, but they are not the same. See Lingo for more information.
 
What should I do if my contact lenses feel dry?
It is always wise to carry contact lens comfort drops in your handbag or back pocket. The preservative-free single use drops are best recommended and may be used as and when required for extra comfort. Environments to watch out for are smoky and dusty places, gyms, where working out causes your body temperature to rise and eyes to dry out as a result, air-conditioned and heated offices, especially when coupled with staring at a computer all day and long-distance driving. Take care to only use drops specified for use with contact lenses and ask your Optometrist if you are unsure.
 
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.
 
How soon can I get contact lenses?
At OPTX, our stock range allows us to fit and supply most established contact lens wearers in an hour. If you are new to contact lenses then more time is required in order to teach you how to insert, remove and take care of the contact lenses. Our patient contact lens fitters will spend all day with you if necessary, so do not feel pressured and take your time as you are introduced to the new world of contact lenses.
 
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.

Term Definition
CataractA cataract refers to any cloudiness within the natural lens of the eye. Most often, this is age-related, but accelerated risk of cataract is now caused by over-exposure to ultra-violet light. This is worsened by the fact that the Ozone Layer is constantly thinning. Our advice is to take care when in the sun and always don a hat and a good pair of UV-blocking sunglasses. Ask your optometrist for more information. If you develop or are developing a cataract, don't worry unnecessarily. The sky does not fall down even though it might be slightly smeary to look at. A simple operation can be performed by an ophthalmologist whereby the cataractous lens of the eye is removed and replaced by a new implant. You will probably be sent home the same day!
