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 a cataract?
A 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!
 
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.
 
Can I use any contact lens solutions or fluids for my lenses?
No. Always discuss your solutions with your Optometrist if you are thinking of changing types. It is quite possible to change from one brand of multipurpose solution to another, however, it is not wise to change from a multipurpose solution to a peroxide type where neutralization is required. Many contact lens wearers have made the mistake of using 3% hydrogen peroxide as a multipurpose solution.

Term Definition
AstigmaticOften the eye is shaped like an egg or football. This is what we call astigmatism. It is quite a normal condition and most of us have to some degree. Like an egg, two main areas of curvature are found: one is flatter and the other is steeper. This causes the light to focus in two different positions such that the steeper or more curved area focuses further forward and the less curved or flatter further back. The effect on vision is to distort shapes so similarly shaped characters become confused. The letter G may be confused with a C and the number 2 may be mistaken for the letter Z.
