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.

What are the advantages of glass lenses over plastic lenses?

Plastic lenses are lighter and have 3 x the impact resistance of glass while glass lenses are thinner.

At the start of spring I can't wear my contact lenses comfortably as my eyes itch - why is this?

You are probably suffering from an eye allergy. Spring often brings about more sneezing and increased pollen counts along with all the daffodils. Certain susceptible individuals will experience a reaction in the eyes and an allergic conjunctivitis results. The itching is usually confined to the upper and/or lower lids and possibly the corner of the eye closest to your nose. If you wear contact lenses, the best thing to do is switch to spectacles for the duration of the allergy and buy a small supply of daily disposable lenses so that you can use them for a few hours out in the evening if you are desperate. Daily disposables would be the best lens type if your allergies are fairly chronic and you refuse to wear glasses. For relief from the itching certain anti-histamine containing drops can be bought from your local pharmacy. Most cannot be used in conjunction with contact lenses. Other types of drops can be used over a sustained period of time to strengthen the membranes of the cells that cause the symptoms of allergy. These drops have a longer-term effect and are called mast-cell stabilizers. The active ingredient is usually sodium cromoglycate. Ask your Optometrist or pharmacist for more information.

What does the eye exam involve?

An Eye Exam allows the Optometrist to:

Determine any relevant prescription for your eyes (far or Near-sighted, Astigmatism, Presbyopia)
Check that the muscles of the eyes work together
Check your Eye Health and screen for any associated general health problems
Perform any further testing as deemed necessary like Eye Pressures, Visual Fields, Color Vision or Pupil Dilation

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.

Bifocals

The gradual decrease in ability of the eye to focus is a natural part of the aging process. Bifocals contain two prescriptions for correcting vision at different distances. Bifocals aid both near and far vision, with a visible line dividing the two areas of power prescription.

Blended multi-focals

These lenses have two focal corrections without the noticeable lines. The area that fuses the two powers together is unusable area.
