And old Creek Indian proverb states, "We warm our hands by the fires we did not build, we drink the water from the wells we did not dig, we eat the fruit of the trees we did not plant, and we stand on the shoulders of giants who have gone before us."
In 1961, the Eye Bank Association of America (EBAA) was formed. This association stewards over 80 eye banks in the US with over 60,000 recipients each year of corneal tissue that restores sight to blind people. Over one million men, women, and children have had vision restored and pain relieved from eye injury or disease. The Eye Bank Association of America is truly a giant whom shoulders that we stand upon today. Their service and foresight into helping patients with blindness is remarkable.
It is important to give back the gift of sight. You may be asking, “how does this affect me?” On the back of your drivers license form there is a box that can be checked for being an organ donor. Many people forego this option because they are not educated on the benefits of it. There are many eye diseases that rob people of sight because of an opacity, pain, or disease process of the cornea. Keratoconus, a disease that causes malformation of the curvature of the cornea, can be treated by a corneal transplant. Chemical burns that cause scarring on the cornea leave people blinded or partially blind. This is another condition that requires a corneal transplant.
When it comes to corneal tissue, virtually everyone is a universal donor, because the cornea is not dependent on blood type. Corneal transplant surgery has a 95% success rate. According to a recent study by EBAA, eye disorders are the 5th costliest to the US economy behind heart disease, cancer, emotional disorders, and pulmonary disease. The cost is incurred when the person, for example, is a working age adult and can no longer hold a job because of vision issues. The gift of a corneal transplant can be one way to restore not only their vision, but their way of life, and their contribution to society.
By becoming a donor, or educating others to consider being an organ donor, you can give the gift of sight to someone on a waiting list. When you educate others to give the precious gift of sight, you become a giant whose shoulders others can stand on. Become a donor today.

The word “astigmatism” is used so much in the optometric world that most people have talked about it when discussing their eye health with their doctor.
“Astigmatism” comes from the Greek “a” - meaning “without” - and “stigma” - meaning “a point.” In technical ocular terms, astigmatism means that instead of there being one point of focus in the eye, there are two. In other words, light merges not on to a singular point, but on two different points.
This is experienced in the real world by blurred, hazy vision, and can sometimes lead to eye strain or headaches if not corrected with either glasses or contact lenses.
Astigmatism is not a disease. In fact, more than 90% of people have some degree of astigmatism.
Astigmatism occurs when the cornea, the clear front surface of the eye like a watch crystal, is not perfectly round. The real-world example we often use to explain astigmatism is the difference between a basketball and a football.
If you cut a basketball in half you get a nice round half of a sphere. That is the shape of a cornea without astigmatism.
If you cut a football in half lengthwise you are left with a curved surface that is not perfectly round. It has a steeper curvature on one side and a flatter curve on the other side. This is an exaggerated example of what a cornea with astigmatism looks like.
The degree of astigmatism and the angle at which it occurs is very different from one person to the next. Therefore, two eyeglass prescriptions are rarely the same because there are an infinite number of shapes the eye can take.
Most astigmatism is “regular astigmatism,” where the two different curvatures to the eye lie 90 degrees apart from one another. Some eye diseases or surgeries of the eye can induce “irregular astigmatism,” where the curvatures are in several different places on the eye’s surface, and often the curvatures are vastly different, leading to a high amount of astigmatism.
Regular astigmatism is treated with glasses, contact lenses, or refractive surgery (PRK or LASIK). Irregular astigmatism, such as that caused by the eye disease keratoconus, usually cannot be treated with these conventional methods. In these circumstances, special contact lenses are needed to treat the condition.
The next time you hear that either you or a loved one has astigmatism, fear not.
It is easily corrected, and although astigmatism can cause your vision to be blurry, it rarely causes any permanent damage to the health of your eyes.
If you experience blurred vision, headaches, or eye strain, having a complete eye exam may lead to a diagnosis and treatment of this easily-dealt-with condition.
