February 9: What YOU need for UV: 1. Modern spectacle lenses can provide layers of UV protection. Polarisation in your lenses significantly reduces the amount of glare (and improves clarity of vision too). Less glare, means less UV directly and indirectly hitting the eye. 2. Request that a specialised UV anti-reflection layer is added to the back surface of the spectacle lens. As explained above in the diagram, UV light reflected off the back of lenses is as damaging as light penetrating through the lens. A back lens surface can reflect up to 90% of incident UV, so it is important to have a protective layer that acts on reflected UV generated by light hitting the back lens surface. This can lower your risk of eye conditions caused by UV damage, such as pterygium. Protecting you from future disease is just as important to us as treating any current conditions. Come in and see us and let us help.

February 4: INDIRECT LIGHT IS THE ISSUE...Research shows that a significant amount of ocular damage occurs due to indirect light – light that comes from the side or slightly behind, or is reflected off the ground, water etc. Continuing from this finding it has been found that peak exposure times for the eyes are "between 8 and 10am and 2 and 4pm for most of the year because of the angle of the sun in relation to the eye at those times". These are typically times when people are less likely to wear sunglasses. Fulltime UVR protection for the eyes is needed, not just when you think the sun is bright.

February 1: Did you know?... That in 2007 the "slip, slop, slap" jingle was updated to include "seek (out shade) and slide (on some sunglasses)"? And, did you know that the peak UV exposure for your eyes occurs between 8 - 10am and 2 - 4pm most of the year? According to the World Health Organisation "your sun exposure behaviour now determines your chances of developing skin cancer or cataracts later in life". Contact Us on 341 4850

December 19: ENJOY EATING, DRINKING, READING OUTSIDE? Don't forget to wear your SUNGLASSES when you are outside. The sunlight is a risk factor for a number of eye conditions, and it can be avoided. Polarised prescription sunglasses are great for blocking out the glare; they enable you to see correctly, clearly and comfortably.

November 30: TREATMENT OF KERATOCONUS: In the early stages keratoconus causes myopia (short-sightedness) and astigmatism, and this can typically be corrected by spectacles. As the condition progresses, the cornea becomes highly irregular and spectacles can no longer adequately correct the vision. At this stage rigid gas permeable contact lenses are required. (Soft contact lenses are typically not an option because they can not correct the irregular astigmatism).

November 26: 
WHO IS AT RISK OF KERATOCONUS? Keratoconus typically affects:individuals who excessively rub their eyes; people who have another 'atopic' disease, such as asthma, eczema, hayfever, allergy; those who have family members affected by keratoconus. Keratoconus has also been associated with Down's syndrome, Marfan's syndrome or mitral valve prolapse. The cause of keratoconus is generally unknown, although recent evidence has suggested a genetic origin for some individuals.

November 9: 
THE FUTURE FOR DRY EYE...Compliance is very important for people with dry eye - watering eyes can actually indicate dry eye, and so people should not cease treatment just because the bottle has run out. Also, if you are not happy with your eyecare regimen, speak to your optometrist. If multiple conservative measures have not been beneficial, or the dry eye has resulted in central corneal staining or reduced vision, then you may be referred to an ophthalmologist. With an increasing prevalence of dry eye, research is being directed at finding solutions to alleviate symptoms.
