Pinhole glasses can be made of light plastic that also look well. People can use pinhole glasses when doing household...more
As a vision anomaly, astigmatism can cause blurry vision. This common vision problem occurs in many people in different degrees. A slight form of astigmatism hardly affects eyesight and requires no medical treatment at all. However, severe forms of astigmatism can cause many consequences such as distorted vision, general eye discomfort and even headache.Blurry vision always results from either incorrectly shaped cornea or a lens with abnormal curvatures. Both of the two abnormalities can cause blurry vision, because they prevent the lens from directly focusing the light on the retina. Although blurry vision is one of the most common symptoms of astigmatism, causes of astigmatism are still unclear. Some children are born with this vision problem, which may either deteriorate or become better as a child matures.People with astigmatism need to see an eye doctor for a comprehensive optometric examination. Currently, the most common treatment for astigmatism is eyewear, including eyeglasses and contact lenses. These lenses should be made with proper prescription of a specific patient.A procedure named orthokeratology can also be used to treat astigmatism. This painless procedure...more

In general, the eyes focus and pupil size are under control of the internal muscles, while external muscles have more responsibilities. External muscles direct the eyes to the right point and keep the retinal image in constant slight motion. In fact, both internal and external muscles are quite important in maintaining good eye health.Like any other muscle system, eye muscles are subject to fatigue after continuously use without breaks. They can be fatigued if the eyes are used for prolonged ocular activity. In addition, those activities that require added effort and concentration can cause eye fatigue more easily. After proper rest, eye muscles can recover their optimal levels of function. Eye muscles do need proper rest and relaxation, similar to other muscles of the body. Excessive eye use can push eye muscles to their limit, which can lead to vision problems. This abuse of the eye prevents eye muscles from restoring to their normal state.Experts have suggested that eye muscles can benefit from exercises, just like the body. A New York ophthalmologist named Dr. William Bates had developed a series of eye exercises for vision improvement, which can eliminate eyeglasses, contact...more
