Do you stock children's' frames?
Yes. Ask about our Fisher designer children frames. Remember to buy your child a frame that fits snugly, but has room for lengthening of its temples and is not too narrow. This way the frame can be readjusted to match your child's facial growth.
 
How often should I have a Sight Test?
We recommend that you have your eyes checked once every year, but this may vary depending upon the nature of your prescription. At the very least, you should have your sight checked once per two years. Should you wear contact lenses, a more frequent interval of every 12 months is advised. These recommended intervals assume that you are not experiencing any symptoms of visual change.
 
What is the difference between an ophthalmologist and an optometrist?
Ophthalmologists are sometimes known as eye surgeons or eye specialists as they concentrate on diagnosing and treating eye diseases. They are essentially medical doctors that specialize in eyes and may perform surgery and prescribe medication as they see fit. Some also undertake the prescription of spectacles, contact lenses and recommend eye exercises, although this is quite rare. Optometrists will screen the eyes for diseases and refer to ophthalmologists if necessary. However, optometrists concentrate on spectacle and contact lens prescriptions. Some specialize in eye exercises to improve eye muscle conditions.
 
How difficult is it to adapt to multifocals?
The first time any spectacles are worn some adjustment time is required mainly because the new, clear vision needs to be accepted by your brain. Once it has learnt to recognize the images seen through the spectacles and become familiar with them, the initial “WOW” effect should have worn off. Multifocals are slightly trickier than single focal specs since they change in power as the eyes look from the top to the bottom of the lenses. Your eyes need to learn which parts of the lens to use when looking either close-up, far-away or in-between. Your Optometrist can advise you on tricks to help you get started and in no time you should be well on your way to successful multifocal wear. A few individuals may struggle with these type of lenses simply because they cannot tolerate the changes in power which is inherent in the design of these. We advise that a period of 4 weeks be allowed before deciding that multifocals are not for you.
 
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.

Term Definition
Long-sightednessAlso known as Far-sight or Hyperopia, long-sighted individuals have difficulty with anything close-up while their general distance vision is not as bad. Light from objects viewed will theoretically focus behind the retina and not on it. However because the eye is able to naturally fatten the lens and cause light to bend more, this error in focus is overcome, which explains why distance vision is generally pretty good. When the same individual tries to look at something up close, much more effort is required, as light from a near object will fall much further back behind the retina. Vision at near is therefore worse.
