Computer Vision Syndrome Highlighted in The Wall Street Journal

Posted on August 17, 2010 | 3 comments

As our population ages and we all spend more time staring at computers, cell phones and the like, computer vision syndrome becomes more of a problem.  In today’s lifestyle section of The Wall Street Journal there is a good article on computer vision syndrome entitled Becoming a Squinter Nation.  We have covered CVS on The Eye Doc Blog as well. A complete list of all of our Computer Vision articles is available via the computer vision tag.

Setting up your computer workstation to minimize the effects of computer vision syndrome is very helpful. For more information for tips on how to do this see our article on Visual Ergonomics – Setting up Your computer Workstation for Maximum Visual Comfort at TotalEyeCare.com.

The Connection Between Light and Migraines

Posted on February 15, 2010 | Comments Off on The Connection Between Light and Migraines

It seems that virtually everyone that has experienced a migraine wants to crawl into a dark room.  The February 2010 issue of the journal Nature Neuroscience has published a study that explains why this phenomena may occur.

The study links a possible connection between light sensitive retinal nerve cells and nerve cells in the brain that are responsible for the perception of migraine pain.  The study noted that blind patients also avoided light when suffering from a migraine, however blind patients that had lost their eye did not avoid light.  The authors concluded that some of the retinal axons, included some light sensitive axons were sending signals to the hypothalamus, a part of the brain that is responsible for the perception of headache pain.
