Give Thanks For your Eyes

0 21 450 Eye 534x276

With Thanksgiving being 24 hours away, we thought this article by the Huffington Post was a perfect way to toast to our eyes on this thankful week. Its also fitting that this article was by written by Visian ICL doctor, Dr. Brian Boxer Wachler. See below the 7 reason why we should give thanks to our eyes.

1. The retina in the back of your eyes are made up of at least 120 million cells that are extremely sensitive to light. Of those cells, between 6 and 7 million of them are “cones,” which allow you to see the color and details of the world surrounding you. The other more than 110 million cells are called “rods,” which help you to see better in the dark and distinguish between black and white. So surprisingly, less than a tenth of your visual receptors actually detect color.

2. On average, you blink around 17 times per minute, 28,800 times per day, and 5.2 million times per year. On that note, you actually blink less when you’re reading, which is why your eyes can feel tired very quickly when you spend a lot of time reading or on the computer. Conversely, you blink more when you’re chatting away! The old saying, “In a blink of an eye” came about because the muscle which allows you to blink is the fastest muscle in the body. A blink typically lasts 100-150 milliseconds, and this action plays a vital role in keeping your eyes moist and debris-free.

3. Your eyes are incredibly adaptable. In fact, if you decided to wear your glasses upside down, your brain would eventually correct your vision on its own. You would see upside down for a few days, but your brain will do marvelous things to ensure survival and would soon process that information into the correct orientation. Pretty cool!

4. The lens in your eyes, which focuses on the object you’re looking at, is faster than any man-made camera on earth. These changes occur almost instantly, before you even realize it’s happening. If it took a second or two like most cameras, things would continually seem like they are out of focus.

5. Your eyes have the best “auto-correct” function around. Whether you’re born with them or they are caused by health conditions such as glaucoma or a stroke, many people have blind spots which would be extremely debilitating if it wasn’t for your brain and your eyes working so well together. These gaps in your vision are essentially “filled in” by the brain, completing the picture that you see in front of you despite having a missing piece or two.

6. Your eyes are made up of more than 2 million working parts that function in unison to create vision. While doctors have not yet been able to transplant eyeballs from human to human due to the sensitivity of the optic nerve, surprisingly enough shark corneas (yes, sharks!) are very similar to ours and research is underway to discover if they can successfully be used in human transplantation.

7. Eye color is controlled by the level of melanin in your iris. Brown yes have more melanin (a dark pigment) in the iris, and blue eyes have less melanin which allows blue collagen to show through. Interestingly enough, if you have blue eyes then you share a common ancestor with every other blue-eyed person in the world. The first person ever to have blue eyes lived somewhere between 6,000 and 10,000 years ago. Before then, all people had brown eyes!

Important Safety Information

The Visian ICL is intended for the correction of moderate to high nearsightedness. Visian ICL and Visian TICL surgery is intended to safely and effectively correct nearsightedness between -3.0 D to -15.0 D, the reduction in nearsightedness up to -20.0 D and treatment of astigmatism from 1.0 D to 4.0 D. If you have nearsightedness within these ranges, Visian ICL surgery may improve your distance vision without eyeglasses or contact lenses. Because the Visian ICL corrects for distance vision, it does not eliminate the need for reading glasses, you may require them at some point, even if you have never worn them before.

Implantation of the Visian ICL is a surgical procedure, and as such, carries potentially serious risks. Please discuss the risks with your eye care professional. Complications, although rare, may include need for additional surgical procedures, inflammation, loss of cells from the back surface of the cornea, increase in eye pressure, and cataracts.

You should NOT have Visian ICL surgery if:

  • Your doctor determines that the shape of your eye is not an appropriate fit for the Visian ICL
  • You are pregnant or nursing
  • You do not meet the minimum endothelial cell density for your age at the time of implantation as determined by your eye doctor
  • Your vision is not stable as determined by your eye doctor

Before considering Visian ICL surgery you should have a complete eye examination and talk with your eye care professional about Visian ICL surgery, especially the potential benefits, risks, and complications. You should discuss the time needed for healing after surgery. For additional information with potential benefits, risks and complications please visit DiscoverICL.com
