Eyeglasses have been around for years. Historians claim Italian monks are responsible for the invention of what we know and depend on today as eyeglasses — way back in the early 1200s. Small magnifying eyeglasses, set or tied into bone or leather, were the beginning design of the eyeglasses we wear today. It wasn’t until the 1400s that corrective lenses were born. The first pair of lenses helped farsighted individuals. Years later, in 1825, British astronomer George Airy created the first pair of cylindrical eyeglass lens to correct his own astigmatism (curvature of the eye’s cornea that can impact vision). This became the solution for correcting all cases of astigmatism moving forward.
Astigmatism occurs in about , but researchers are still unclear about how it develops. For some, it is hereditary — these individuals are born with a misshaped cornea. Occasionally, intense trauma to the head can cause astigmatism to develop.
The most interesting part? “Everyone has some degree of astigmatism,” states VSP network doctor Randall Fuerst. But slight astigmatism doesn’t affect vision or require treatment. In fact, most people likely don’t even know they have it. That is because the symptoms can be easy to miss. Headaches, eye fatigue and dizziness are common symptoms of astigmatism, making it difficult to self-diagnose.
If you have astigmatism, there is a solution to the problem, no matter how severe your astigmatism is. Containing special cylindrical lens prescription, astigmatism can be corrected with eyeglasses. Contacts are also a solution for astigmatism. Although, contacts require regular cleaning.
Seeing double causes triple the trouble, making everyday life frustrating. Double vision, medically known as diplopia, can be caused in many ways — by a head or brain injury, dry eyes or paralysis to name a few. And double vision doesn’t always affect both eyes. Astigmatism can also cause double vision. As you can imagine, seeing two images of a single object can cause symptoms of dizziness, nausea and fatigue. Both children and adults can develop double vision and experience the same symptoms. Depending on the cause, double vision can be corrected by eyeglasses or contact lenses, depending on the patient’s preference.
If you think you have astigmatism or double vision, you should schedule an appointment with a VSP doctor in your area today.
