Avatude - Blue light filtering glasses

Not all blue light is bad - some exposure is good for our health. 


Sunlight is the main source of blue light but there are also man-made sources. Fluorescent and LED lighting, flat-screen televisions, computers, smartphones and other digital devices all emit significant amounts of blue light. The amount of blue light from these devices is small compared to what comes from the sun. But the amount of time that people spend, with a these devices at close range, raises concerns about possible long-term effects of blue light over-exposure on eye health.

We are mindful of potential long term health effects of prolonged exposure to blue light, and the short term disruptive effects blue light may have on our daily circadian rhythms. Blue light exposure is implicated in eye strain symptoms, dry eyes and can interfere with sleep patterns. We experience comfort and relief when it is filtered out. This is an easy step if you are already wearing glasses, but what if you don’t need personalized prescription lenses?

 Avatude are glasses with optical grade, blue light filtering lenses. These are going to prove popular for anyone spending long hours on screens, including children. Available in a variety of frame styles, sizes, powered and non prescription lenses – there is something for everyone.

Plastic bags and packaging are much talked about at the moment! So if you want to reduce your plastic waste this year remember we can recycle your contact lens packaging. These are small items but every little bit helps.

Most disposable contact lens blisters are classified #5/PP Plastic, a designation shared by a wide range of medical and food packaging. Save these and drop them in to us for recycling. 

The cartons and cardboard packing are recyclable paper and can go in your regular household collection. The small piece of foil topping is the only part of packaging which should be discarded. Remember used contact lenses themselves go in the bin - not down the sink. Just one more way we can help protect our environment.

Does blurry distance vision mean you are short sighted?

Behavioural Optometrist Sally Adams shares Vision Therapy case notes. 

Paul, aged 8 years, came to see me because he could not read what his teacher had written on the board, and he was having headaches. His eye examination showed he was not short sighted, even though his  vision was blurry to the extent he would have failed the driving vision test, and his 3D vision was reduced.

Paul’s focus was not flexing normally and his eye movements for reading were not smooth. So he was not focussed on where he was looking, making reading a struggle.

Vision therapy for Paul was two fold; he started using reading glasses to reduce focusing stress, combined with vision exercises to improve the flexibility and accuracy of his focusing and eye tracking system. Within only a few weeks Paul’s distance vision returned to better than 20/20, his 3D vision returned to normal, and his headaches had reduced.  The next step was to help him maintain this improvement so he would not suffer with the same problems again. He worked through 12 sessions of vision therapy with me for 30 minutes each week, while at home he completed 10 to 15 minutes of vision activities each day. With practice and commitment Paul’s vision system is automatically working efficiently which means he sees clearly and comfortably.

How eye disorders may have influenced the work of famous painters

Visual art invites us to view the world seen through the eyes of the artist or creator. This concept is very familiar to us with modern art, there is a role for interpretation. However a few hundred
years ago, the artists of the day were typically creating more real life images of their subject matter.

There is a long history of scientists and clinicians arguing particular artists were affected by vision disorders, based on signs in their works. Included is the hypothesis that leaders of the Impressionist movement were short- sighted, for instance, and that their blurry distance vision may explain their broad, impetuous style.

The fact that Claude Monet had cataracts is well documented and seen in the changing colours of his paintings. In other cases supporting evidence of such disorders and their influence on artworks is often speculative, and hampered by a lack of clinical records to support the diagnosis. There is still fun in speculating, did El Greco suffer from astigmatism? Perhaps Australian painter Clifton Pugh had a colour vision deficit?
