Tell me about one day contacts
Daily disposable contact lenses (CLs) have made things much more convenient for people who want contact lenses part-time. This suits people who wear glasses most of the time, but like an occasional change, or for people wanting to wear contact lenses for specific purposes - like going out, sports, holidays or special occasions.
Daily disposable CLs now come in a wide range of prescription powers, and in a variety of colours. They also come into their own for people with dry eyes, tear film problems and allergy - because each day is a fresh new lens.
Depending on the condition of your eyes, you may be eligible for Medicare funding for the fitting of contact lenses - be sure to ask.
Eye Health Facts
Aura, after-images and things like that.
Most of the time our vision works automatically, adjusting to changing light levels, colours and shapes and movement, without us noticing the complex task it is performing. But in certain situations so often we get a glimpse at the workings of our visual system:
- Bleaching takes place when you look at something bright - it takes a little while for the 'afterimage' to fade and vision return to normal.
- Look at an object of a bright colour for a while, and then at a white page, and you'll see an 'afterimage' in its complementary colour.
- Stare at an object of a bright colour against a blank background for a while, and because of the small movements the eye makes, this complementary colour afterimage will appear as an 'aura' at the edges of the object.
