Cloudy Crystalline Lens – the Cataract!

sim-cataractCataracts are one of the leading causes of blindness in the world. Cataracts are formed when the natural crystalline lens in the eye becomes clouded or opaque. Cataracts can be removed surgically once they become significant enough. Cataract progression can be minimized by wearing sunglasses to block harmful UV light from entering the eye. Nutrition has also been found to play a role in minimizing cataract progression. Many studies have shown that the vitamins C and E are helpful in delaying cataract formation. Studies have also shown that the daily intake of the carotenoid antioxidants lutein and zeaxanthin, the only carotenoids found in the lens, can be beneficial as well. These nutrients can be obtained through a healthy diet of fruits and vegetables, or through vitamin supplementation. Many eye doctors carry supplements in potencies stronger than that which can be obtained over-the-counter, as these nutrients have also been found to benefit the area of the retina called the macula.

What is a cataract?

Many people have heard the term cataract before, but are unsure as to what exactly it is. A cataract is a clouding of the natural crystalline lens of the eye. This lens sits right behind the iris, the colored part of the eye. It is used to help focus when reading at near. Due to ageing, ultra-violet light exposure, injury, or certain medications, it can start to yellow and become opaque. This clouded lens, or cataract, can cause a glasses prescription change, glare, blur, and washing out of colors. Once the visual symptoms become bothersome enough, your optometrist will refer you to an eye surgeon to have it removed. An artificial lens is then inserted into the eye to help maintain the optical power of the eye.
One of the best ways to slow down the progression of cataracts or delay their onset is to protect your eyes from UV light. This can be achieved by wearing sunglasses when outdoors. This is important year round, not just in the summer months. Your optometrist will monitor for any cataract changes at your yearly eye exam.

Eyes in the Sun

Exposure to the sun may be damaging to the eyes just as it is to the skin.  The sun emits UV-A and UV-B radiation that is absorbed by the tissues in the front and back of the eye.  This can result in an increased risk of cancers in all the different areas of the eye.  It may also increase the risk of certain types of cataracts and macular degeneration.  Although cataracts may be improved with surgery, macular degeneration is a leading cause of blindness as we age.  It is very important to wear good sun protection that covers the eyes well and has adequate UV-A and UV-B protection.  Also most of us remember to wear our sunglasses in the summer, but it is just as important to wear them in the winter when UV radiation may be just as intense.  Finally, remember to continue annual eye exams with your eye doctor to diagnose and monitor any problems that may result.

The Lens of the Eye

The lens of the eye or often called the natural lens, is a transparent bioconvex structure positioned behind the pupil. The lens and the corneal are the predominate refracting surfaces of the eye…..that is they provide the power or our prescription in order to see. The internal structure of the lens allows for a large amount of elasticity to thicken or thin its size. This property of elasticity provides the eye the increased power to do most near tasks, as in reading. However, as we age, the lens gradually loses this elasticity, so by the age of 45 years, we have to supplement this loss with reading glasses. This decrease of elasticity or power is called presbyopia. Any loss in the transparency of the lens , which can greatly reduce our vision, is called an opacity or a cataract. We as optometrists during a normal comprehensive vision examination will evaluate the elasticity and transparency of the lens.
