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.

What are polarized lenses?

These are special tinted lenses that polarize light as it passes through. This means that light from only certain planes is allowed to pass through while the rest is eliminated. Visually, the effect would be to get rid of unwanted stray light. This can be quite useful for the avid fisherman, for example, who wants to see just beneath the surface of the water without having to worry about distracting reflections from the surface. They can be made with or without prescription, but may take slightly longer to put together as they need to be ordered. Ask your dispenser for more information on these lenses.

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.

Is my prescription the same for both specs and contact lenses?

No. A contact lens prescription is only 100% complete when the details of their fit are included. This means that although the powers may seem similar to your spectacle prescription, the powers alone are not sufficient when specifying a contact lens prescription. Additional parameters like lens type, diameter and base curve must also be included.

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.
