Eye glasses, sometimes called spectacles or optical glasses, are visual contact eyewear, often consisting of durable hard plastic or glass lenses mounted in an eyeglass frame that holds them above a person’s eyes, usually using a rim over the eye and hinges around the bridge above the nose. Because of their shape and design, eye glasses are also sometimes called reading glasses or corrective eyewear since they correct vision for people who use glasses or contact lenses. Today, eye glasses come in many different shapes and designs. Some are more streamlined and decorative, resembling glasses used by professional sportsmen. Others, designed for sports-enthusiasts, have large, extended lenses that look like sunglasses.
There are many reasons why people wear eyewear. For some people, wearing eyewear can improve a person’s vision and eliminate blurry vision. In addition, some people wear eyewear to protect their eyes from glare or sun damage. And others wear eyewear for cosmetic or functional reasons, such as correcting nearsightedness, farsightedness or astigmatism.Most eye glasses are corrective, meaning that they correct vision for nearsightedness, hyperopia (farsightedness) or astigmatism. The design of eye glasses is such that light rays entering the eye cannot pass through the top part of the lens and focus on the bottom half, or the cornea. This is accomplished through a special design. One design allows the light rays to focus on the retina at the back of the eye and the pupil in the center. This design enables light rays to enter the eye through both the top and bottom half.
The other design is called a toric lens. This design allows the light to focus onto the retina only on one side. The result is the same as having a thin wafer-like sheet covering the inside of the eye, but without the middle part. Both types of designs are used to treat nearsightedness, farsightedness and astigmatism. They are available for all generations, including newborn babies, and they come in various sizes.
There are many benefits to using eye glasses. Some of these include: * corrective for either nearsightedness farsightedness or astigmatism; * eliminates eyestrain; * improves eye coordination; * provides safety in driving; * improves appearance; * improves eye-hand coordination; * may help prevent age-related eye diseases; * provides comfort, relaxation and a better way to focus. These benefits also apply to pregnant women who wear glasses. Pregnant women can benefit from the improved eye coordination, safer driving and comfort that wearing eye glasses provides.
It is important to be sure that one is purchasing a design that works well with one’s eye. Not everyone’s eyes are the same size, shape or design. This can make choosing the correct design a difficult task. When a professional optometrist is used to the patient and design of the eye surgery, the process becomes much easier. The professional will create a custom fitting chart for each patient according to one’s eye measurements and design needs. This ensures that eye glasses will be the right fit for each patient.
