Aging eye is a natural age-related condition, in medical terms it is called presbyopia. Beginning in the early to mid-forties, most adults may start to experience problems with near focusing and cannot see clearly at close distances.
This change in the eye's focusing ability will continue to progress over time. This problem remains unnoticeable for years because it develops slowly. At first it affects one of the eyes only. The brain automatically compensates the deteoration of the affected eye, but only for a while. Later on the brain gives it up and one of the eyes remains weaker.
Anyone over the age of 40 is at risk for developing presbyopia. Everyone experiences some loss of focusing power for near objects as they age, but some will notice this more than others.
Presbyopia affects quality of life. People who become presbyopic may complain of headaches and eye strain, experience blurred near vision when reading and hold objects progressively further away from their eyes in order to be able to focus on them.
Presbyopia is widespread in the United States. According to U.S. Census Bureau data, over 140 million Americans were age 40 and older in 2010, and the country is growing older: the median age reached 37.2 in 2010, up 1.9 years since 2000.
More than a billion people in the world are suffering from presbyopic symptons which makes it a pressing health problem world-wide.
When you switch the glasses on the test program is launched first, which tells the weaker eye. The training program is to improve your vision.
The glasses leave the field of vision for the weaker eye free while closing the field of vision for the stronger eye every two seconds. This induces the weaker eye to focus again and again, which under normal circumstances you'd not even try.
By intermittently suppressing the dominant eye, the device forces the weaker eye to try again and again to form a sharp focused image of the objects in the visual field. This eye exercise helps to restore the balance between the eyes and reduces blurred vision at a normal reading distance.
A few minutes of easy but intensive sight training could stop or even revers the deterioration of your eyesight that comes with age!
