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.

Why do we become more "far-sighted" as we grow older?

This is due to a progressive change that occurs within the natural lens of the eye and is called Presbyopia. Although similar to far-sightedness in its effect, these two conditions are not identical. Please see far-sightedness and presbyopia for more information.

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.

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.

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.
