Another article from Linda M. in regards to progress made researching ETS (nothing too crazy, but it sounds like more to come!)

Updates on ETS
- Thread starter corbinam
- Start date
Thank you corbinam for making that post. Reading several of the articles renewed in me a spirit that had been slowly slipping away. Since the articles in question did not include the one on ETS (although I did enjoy it), I will simply say thank you for the link.

well, there is big can of worms there
NG is human optometrist and what I am hearing from the testing these case studies are largely biased and might be scientifically compromised.
As NG stating the best jumping dogs have no refraction errors translating to human vision 20/20.... duh, there is one small problem here ... there is no dogs that have 20/20 vision
here is blog which shows what dogs are actually seeing... does it look like 20/20 to you?

I've read several people's opinions that disagree with some of the things represented in that article.

People may agree or disagree and have different opinions, but going to local trials and picking up few dogs that have jumping issues and doing eye testing is not a science experiment in my book. There are too many variables exist that will need to be removed for even small case study to create valid conclusions- structure, breed, flooring, footing, training, venues dog competes, age, eye set, handling beliefs to name a few.
Not only that but we can not come from same stand point in viewing dog´s vision as human´s. Dogs simply do not use it same way humans do. Example- I can put a hide/odor/ in very clear obvious area and dog still will be searching using his nose.
Additionally undiagnosable vision issues might not be related to vision at all
http://jn.physiology.org/content/41/4/896.abstract
What if the puppy vision was not stimulated during critical period of development? Because that period is short and by the time handler picks up 8 weeks old puppy all brain functions are formed. Something akin to those cases when in the past human babies were raised by animals, if they were returned to humans past 6 year old they were never able to learn human speech.
I am not saying that ETS does not exist, what I am saying that going around labeling dogs as having ETS based on jumping problems, not finding current eye problems and not being able to fix it with jump retraining is not science in my book.
here is another article, food for the thought

BTW, the article author is hugely talented visual artist who spend years building art on tricks of visual perception
