Although there are many different reasons why poor eyesight can develop, recent studies have shown that stress and anxiety have a big impact and are major contributing factors. Very few people are born with visual abnormalities and defective eyesight tends to be acquired later on in life and is related to environmental, cultural, and psychological conditions.
These findings have wide-ranging implications because at least half of the population of the USA either wears prescription glasses or contact lenses and there are many others who are simply unaware that they have visual problems. In the western world, inappropriate response to stress has been cited as one of the primary causes of many of the common ailments that plague modern society.
The good news is that there are a variety of natural treatments that are available which can be used to address the root cause of the problem in order to rectify visual abnormalities such as nearsightedness, farsightedness, astigmatism, or light sensitivity without needing to wear glasses or contact lenses. Learning how to relax the eye muscles and break the habit of straining is crucial, especially when it comes to blurry vision which can be corrected by allowing the whole visual system to rebalance itself.
Overuse and lack of adequate visual rest are common ways in which eyesight can become sabotaged and this is why relaxation techniques are so useful and important. Constant straining will lead to the eye muscles becoming tense and the retina becoming desensitized (letting go of this strain and resting the eyes can be very difficult if the habit has become established over many years). Once these issues have been addressed, the eyes can start to respond to visual experiences in a more relaxed manner which will improve the quality of your vision.
