Colour Vision Deteriorates with age

Have you had your eyes tested lately?

Optometrist

Cells in the retina that are responsible for normal colour vision decline in sensitivity as we age, causing colours to become less bright and the contrast between different colours to be less noticeable. You may not notice it as it has happened slowly over time but it might be worth getting your eyes checked. Particularly if you are over 70.

Abnormal colour vision increases significantly with aging – affecting one-half or more of people in the oldest age groups, reports a study in Optometry and Vision Science, the official journal of  American Academy of Optometry. The journal is published by Lippincott Williams & Wilkins, a part of Wolters Kluwer Health.

While few people younger than 70 have problems with colour vision, the rate increases rapidly through later decades of life, according to research by Marilyn E. Schneck, PhD, and colleagues of The Smith-Kettlewell Eye Research Institute, San Francisco. They write, “We find the colour discrimination declines with age and that the majority of colour defects among the older population are of the blue-yellow type.”

The researchers administered colour vision tests to a random sample of 865 older adults — age range 58 to 102 years. The study excluded subjects with any type of congenital colour-vision defect (“colour blindness.”). The types and rates of colour vision abnormalities were assessed in different age groups.

Overall, 40 percent of the participants had abnormal results on one of the two colour vision tests used in the study. Twenty percent failed both tests.

The failure rate was markedly higher in older age groups. Although colour-vision abnormalities were uncommon in people younger than 70, they were present in about 45 percent of people in their mid-70s, up to 50 percent of those 85 and older, and nearly two-thirds of those in their mid-90s.

Nearly 80 percent of the abnormalities involved confusion of the lighter (pastel) shades of blue versus purple and yellow versus green and yellow-green. These “blue-yellow” errors are distinct from the “red-green” errors observed in people with inherited colour blindness, which affects about eight percent of males and 0.5 percent of females. Although the two tests had different failure rates, they detected similar frequencies of blue-yellow errors.

More Severe Defects May Affect Daily Functioning

The results confirm previous studies showing that colour vision “deteriorates measurably” with aging. Most subtle aging-related colour vision abnormalities are likely to go unnoticed, the researchers suggest.

However, they note that nearly 20 percent of older adults failed the easier of the two tests, “designed to only detect defects sufficiently severe to affect performance in daily life.” Dr Schneck and co-authors note, “These individuals would have problems carrying out some tasks that rely on colour vision.”

The researchers discuss factors that may contribute to changes in colour vision with aging, and to blue-yellow defects in particular. These may include reduced pupil size, admitting less light into the eye; increased yellowing of the lens inside the eye; and changes in the sensitivity of the vision pathways. All of these are known changes with age to the human eye.

Increased rates of eye diseases are another potentially important contributor. Dr Schneck and co-authors add, “The most common age-related eye diseases (glaucoma, age-related macular degeneration, and diabetic eye disease) all produce blue-yellow colour vision anomalies, at least in the preclinical or early stages.”

While there is no treatment for this normal, age-related loss of colour perception, you should be aware of this loss if your profession requires fine colour discrimination. If you think you aren’t seeing colours as you should, head to our practitioner page to find a colour vision Optometrist near you.

Why regular vision checks are important at any age

As we all know our vision and the gift of sight is one of the most important and precious gifts we have, but sadly many people wait until they have problems before they see an optometrist. An eye exam is the first step to fix vision problems, the severity of the problem can be reduced if caught with early enough with regular eye exams.

eye-examination-28825735Eye exams have many benefits, as eyes change as we age, we need to stay on top of this to ensure our eyewear prescription is up to date. An essential part of the comprehensive eye exam is the dilated eye exam. This allows your Optometrist to view inside your eye as the drops placed in the eye widen the pupil, which enables your optometrist to see important tissues at the back of the eye, including the retina, the macula and the optic nerve. These check-ups are the best technique for early diagnosis of sight-threatening eye diseases like age-related macular degeneration, diabetic retinopathy, glaucoma, plus many other conditions.

Eye exams can also check alignment in the eyes as sometimes our eyes don’t always work together like they’re supposed to. Patients can often be in pain with crossed or turned eyes with extra strain on nerves and muscles. The alignment can also evaluate the eyes to check if they are focusing at different rates, which can cause blurriness and headaches. Eye exams can also check your eye tone, which measures the muscles that allow the eyes to change focus from short to long range, which may over time diminish due to weak and aging muscles. Corrective lenses can help relieve stress on the muscles and relieve symptoms like blurriness and headaches.

Retina exams are necessary because the blood vessels of the retina are excellent indicators for diabetes and high blood pressure, both life-threatening conditions. Though painless, glaucoma can lead to severe degenerative vision issues that can lead to blindness. Glaucoma generally has no symptoms at early onset, and a routine eye exam can catch the disease before it progresses into a bigger problem.

Diabetic patients need annual exams as they are more susceptible to depleted eye site due to their condition. Diabetes is the number one cause of blindness in adults. If you have diabetes, it is essential to have regular eye exams as your eyesight can change rapidly, especially as you get older. For everyone else, once every two years is the average for a check-up, though if you are over 60 good to be checked out every year as this age group has a higher chance of glaucoma, cataracts and macular degeneration.

Frames and Lenses to be removed from TGA register

Last month ODMA and three other like-minded associations – The Australian Dental Industry Association (ADIA), the Australian Medical Manufacturers and Distributors Association (AMMDA) and the Assistive Technology Suppliers Australasia (ASTA) combined to form The Medical Devices Small Business Coalition, whose mission is to ensure that the needs of small business in the medical devices sector are recognised and supported in government policymaking.  All Members pledge to cooperate in a spirit of mutual understanding and to develop a closer relationship of goodwill and cooperation to support small businesses in the medical devices sector.

ODMA Chairman Robert Sparkes and CEO Finola Carey with Greg Hunt, Minister for Health

ODMA Chairman Robert Sparkes and CEO Finola Carey with Greg Hunt, Minister for Health

The coalition was launched at an event at Parliament House in Canberra and attended by the Minister for Health, the Honourable Greg Hunt, who officiated.

ODMA CEO, Finola Carey raised a number of issues with The Minister including the anomalous situation of GST being charged on medical frames whilst classified a medical device for TGA purposes.

They also discussed Health Funds controlling the issue of Provider Numbers to independent dispensers opening new outlets when they are essentially in competition, plus the classification of frames and lenses as Class 1 Medical devices necessitating paid registrations with the TGA.

The good news is, that following this launch ODMA represented by Chairman Robert Sparkes and Richard Grills participated in several meetings with TGA with the TGA agreeing to remove BOTH optical frames and optical lenses from the ARTG as Class 1 Medical Devices.  The date of removal has yet to be advised but will be in the next few months.

 

Do’s and Don’ts to improve your eyesight

eyechart-780x405

Following are some do’s and don’ts’ you need to follow for a healthy vision.

  1. DO eat foods that are rich in Vitamin A, Vitamin C, beta-carotene, and Lutein as they help to repair the eyes, such as cod liver oil, sweet potatoes, papaya, butter, grapes, blueberries, and apricot.
  2. DON’T say no to greens, kids! Snack on kale, collard greens, spinach, zucchini, and brussel sprouts.
  3. DO get sufficient rest, since sleep lets overworked eye muscles to relax completely.
  4. DON’T stay involved in one activity for long. Take regular breaks in every visual activity just for 5-10 minutes to rest your eyes.
  5. DO increase your water intake, if your eyes are often blurry, dry, or tired.
  6. DON’T just rinse your face. Every time you have a few extra minutes, fill your mouth with water and then splash water with eyes wide open. This will make you feel fresh and relaxed.
  7. DO relaxation exercises. Place your hands together palm to palm and rub them together efficiently, creating heat. Place them over your eyes; it also helps your eyes to relax.
  8. DON’T let the light directly in whenever you’re exercising your eyes. These exercises will help your eyes to not get tired when you are sitting in front of a computer for hours.
  9. DO eat carrots and other foods rich in beta-carotene which gives food their respective orange hue. It helps promote eye health and corrects vision.
  10. DON’T forget Omega 3 found in cold-fish and nuts. These fatty acids help to stop age-related eyesight deterioration and keep your retinas healthy.
  11. DOavoid sugary foods as they have bad effects on your eyes. The more the sugar you eat, the worst will your eyesight grow.
  12. DON’T It has been connected to a bigger risk of developing age-related macular degeneration, optic nerve damage, and cataract.
  13. DO focus on an object that is at least 20 feet away, for 20 seconds, every 20 minutes. You’ll be astonished at how better your eyes feel.
  14. DON’T stare at gadgets for too long. The brightness level of your computer screen and the phone should be at the lower level as it reduces strain.
  15. DO eat bilberry as it is filled with antioxidants and will play a defensive role and increases blood circulation in your eyes.
  16. DON’T depend on your glasses totally. Take off your glasses as often as possible, to promote natural unassisted vision.

What have the Romans ever done for us?

quote-what-have-the-romans-ever-done-for-us-john-cleese-62-19-11

Not for Profit Association Members often ask what does my Association do for me? Particularly in the industry group sector. One answer is “provides advocacy”, but how can this be measured? Advocacy is a bit like advertising in this context. It definitely works but what part works best – no one really knows.

As the CEO of a small optical industry group with just 70 Members resources are limited and as a result, we need to choose wisely to advocate on behalf of and represent our members’ best interests.  

Recently in the space of two weeks, I attended these events to advocate for and represent the members of our Association:

1. UNSW SOVS Visiting Committee where discussion (amongst other matters) surrounded the selection of the new Head of School for the School of Optometry and Vision Science and access to optometry for underprivileged and rural communities.

2. Standards Australia’s Nominating Organisations Forum – Shaping the strategy in how Australian standards are formulated and funded into the future.

3. Macular Disease Foundation’s Australia National Action Plan Workshop – Developing plans for a united approach to assist the macular disease community. 

4. Optometry 2040 Workshop – Posing and answering the big questions ie, What might optometry and the sector look like in 2040?  

5. Australian Institute of Company Directors Annual Essential Director Update – looking at the latest challenges facing company directors and the endless compliance rules that are now applicable to our voluntary Board. Association Board Members are required to uphold the same standards as any director in a public company like BHP. 

How can our members measure the value and level of this advocacy?  

It might not pay off for 10 years and there will certainly be no change next week. Though things we have worked on over the years like removing duty on optical frames, our Start Your Own Practice models, and updating the Standard for sunglasses have benefited everyone.  

Association Membership should be a marathon, not a sprint.  So, should members be able to dip in and out when they perceive they can see results? Or when there is a big issue or cause?  Well yes, they should as membership is voluntary. However, Members that see the big picture and want to shape the future for their industry are the ones that understand the day to day value of lifelong membership. 

Without Associations voices and input at these types of meetings, who will represent an industry?, Who will see the big picture and shape that industry’s future?

These days when posed the question, What does my Association do for me? , I often just smile and think of the scene in the movie The Life of Brian from the brilliant Monty Python team – “What have the Romans ever done for us?” – before launching into my explanation.

HOYA Corporation announces a new product launch: MyoSmart with D.I.M.S. Technology to reduce myopia progression in myopic children and teenagers

ODMA Member, Hoya Lenses has announced a roll out of  “D.I.M.S. Technology”. Clinical research shows children wearing the lenses have significantly less myopia progression as compared with those wearing the single-vision lenses. WEB_HOYA_MyoSmart_Lens

 HOYA Corporation, a key player in the global market for ophthalmic lenses, is proud to announce a new product launch in the Asian Summer 2018: MyoSmart with D.I.M.S. Technology, a lens for myopia control in children and youth, developed in cooperation with their partner, The Hong Kong Polytechnic University. Wearing defocus spectacles daily significantly slows myopia progression and axial elongation in myopic school children aged 8 to 13, according to a two-year double-blind randomised clinical trial in which 160 Chinese myopic children in Hong
Kong participated.

Following the trial, which began in 2014, children wearing defocus lenses had 60 per cent less myopia progression and in 21.5 per cent of the children, the myopia progression halted completely. The findings provide strong evidence that defocus lenses are effective in reducing myopia progression. In 2012, HOYA Corporation and The Hong Kong Polytechnic University launched a cooperation with the focus on developing a new myopia control lens which is capable of preventing myopia from worsening or slowing down its progression.

Following years of academic studies, product design and clinical research, HOYA Corporation and The Hong Kong Polytechnic University developed a revolutionary spectacle lens, based
on a Defocus Incorporated Multiple Segments Technology or “D.I.M.S. Technology”, which just successfully won the Grand Prize, Grand Award and Gold Medal at the 46th International
Exhibition of Inventions of Geneva in April 2018. WEB_HOYA_MyoSmart_KeyVisual

The lens, which has a smooth surface and looks almost identical to a regular lens was presented on the 6 March at a symposium in Shanghai which was organized by Hoya. A second successful symposium for key opinion leaders, “Symposium of Defocus Theory and Clinical Results in Myopia Control”, was held at Hong Kong Hyatt Regency Hotel on 25 April,
organized by Hoya Lens HK Ltd. and the Global Marketing team. Both events were attended by over 30 key opinion leaders and the D.I.M.S. Technology was very well received.
MyoSmart lenses will be launched in Hong Kong and China in the summer of 2018. A broader, global launch is slated to begin in 2019/2020. At this stage, we do not have a launch date for Australia and New Zealand.

Australian Event for the industry by the industry – O-SHOW second showing confirms boutique event’s popularity!

The Australian optical industry has come out in support of the second edition of O-Show, which was held in Melbourne in July. At ODMA we believe in Australian run Events for the Australian industry = events for the industry by the industry.

Robert Sparkes Chairman of ODMA says “We have been delighted with the look and feel of the OSHOW, with excellent feedback from both visitors and exhibitors. This pop-up boutique event is what the independent optical industry asked for and is now a confirmed favourite.” He added, “this is the kind of show that could easily move to Sydney, Brisbane or other locations if there is a demand.”

If you are into stats, here are some facts and figures – OSHOW brought more than 702 industry visits over the 2 days from 640 individuals. Most of the visitors were from the host state of Victoria (77%) followed by New South Wales and QLD with 8%. There was also a small attendance of international visitors.

One thing we noticed was that 250 people who were pre-registered did not attend.  A post-show analysis of these names showed it is common for one staff member to pre-register everyone in a practice but not everyone goes. This is very disappointing, though when we cross-referenced this with attendees it showed someone from the practice usually attended. Perhaps it is something to be mindful of if you are RSVP’ing to attend events in the future to be realistic about attendees and that it is unlikely the whole practice may come.

We look forward to seeing you at the next pop up OSHOW event – but the most important event to prepare for is O=MEGA19 on the 19th-21st of July 2019. Held at the new extension of the Melbourne Convention & Exhibition Centre. This is an exciting new collaboration between ODMA and Optometry Victoria and is the biggest ever seen in Australia. Supporting the Australian Optical industry by the Australian Optical industry!

ODMA and Optometry Victoria launch O=MEGA19

ODMA and Optometry Victoria have announced the most significant change to the optometric
conferences and events landscape in Australia for many years. The two market leaders in optics
education and events have joined forces to launch O=MEGA19, a biennial event which will be the
largest education, eye care and eyewear event ever seen in Australia.
Replacing SRC and ODMA19, O=MEGA combines the most credentialed and largest annual
optometry conference in the Southern Hemisphere with the largest eye care and eyewear show in
Australia.
Speaking at the O=MEGA19 brand launch at OShow in Melbourne, ODMA Chairman Rob Sparkes
said “In the new global landscape of optics we cannot wait for change. We need to deliver change.
We hope the entire industry will embrace this united joint venture.”
Optometry Victoria President Murray Smith said “We think O=MEGA19 will be extraordinary.
O=MEGA19 brings the best of SRC and ODMAFAIR together. We think optometrists and others
involved in the optics industry will really love this opportunity to come together and learn, network,
and work with suppliers to help us all do our jobs better.”
O=MEGA19 will be held in the new expansion at MCEC which is fully integrated with the conference
space. It will have a new modern schedule including dedicated exhibition-only time to suit both
delegates and exhibitors alike. There will also be a 40 point CPD minimum, a new format including
lectures, sponsored sessions, team-based learning and small group workshops, a design junction
fashion eyewear area, and a cocktail party on the Saturday night.
Speaking about the legacy of SRC and ODMA Fair, Murray Smith said “Optometry Victoria is very
proud of SRC and the legacy it has built – many of our members love it. So do we. But the way
continuing education is being delivered is changing, and we need to be at the forefront of that
conversation. O=MEGA19 makes that happen. It’s really exciting and we thank ODMA for their work
with us on this project so far.”
Mr Sparkes concurred: “ODMA Fair and our other products have been the cornerstone of optics
events in Australia for as long as most people can remember. We’re proud of that legacy. In fact, it’s
only because of the strength of our events that we can be so forward-looking and ambitious with
O=MEGA19. It’s a truly exciting initiative and we can’t wait to bring it to market in 2019. ODMA looks
forward to working with Optometry Victoria to deliver an international world class event.”
