How much do you know about how your eyes work? Probably you don't think about them very much - only when something goes wrong and then you realize how precious they are. In fact, you probably spend more time being concerned about your teeth!
There is a lot we still need to learn about the eye. New research is appearing from neuroscientists updating current information - despite the view of opticians in the 1940s and 1950s that there was no more to discover. In February 2002, scientists at Brown University, Rhode Island, USA announced the discovery of a third photoreceptor deep in the retina of rats' eyes and it is quite likely that we have the same cells. (The other two photoreceptors are rods and cones.) The new cells appear to play an important part in setting the body's internal 24-hour clock. According to Dr David Benson, "It is a visual system that runs parallel to the one we have been thinking about all these years. Now we have to rethink how the retina works and how the brain understands what is going on in the visual world."
Remember his lack of certainty if you are considering Lasik (laser) eye surgery, and you should be aware that there is a risk to night vision. Current advice from the Food and Drugs Administration of the USA is: "A patient may no longer be able to drive a car at night or in certain weather conditions, such as fog." For this reason, laser light correction is banned by the armed services, most police, fire and ambulance services and the Civil Aviation Authority for pilots' licences.
Before you do anything drastic, consider using a Tibetan Eye Chart. The Tibetan Eye Chart is a fun way to help underused eye muscles regain their flexibility and can eliminate astigmatism. The Tibetan Eye Chart is a simple pattern designed to be used in combination with several eye exercises. And here's the good news, the Tibetan Eye Chart is now available for use on your iPad and iPhone so it's easier than ever to use. Check out TibetanEyeChartApp.com to get your copy today.
