Blue light

There is a lot of current discussion about blue light and its effect on the eyes.  The reason for the increased concern is the amount of time we spend on digital devices that emit blue light.  Because of the relative newness of these devices, we are not positive of the long term effects of blue light.  We do know however that it has an adverse effect on the cells in the retina, the back portion of the eye that light is focused on.  Most of the optometric community believes it is important to protect our patients from these harmful rays.  There are several ways to do this.

  1. You can increase the macular pigment density in your eye by increasing the amount of Lutein and Zeazanthin in your diet. Eating lots of kale, spinach, orange bell peppers, paprika and corn is one way to increase you macular pigment or you can take supplements.
  2. Many companies like Apple have put blue light settings on their devices so you can turn them off.
  3. You can have coatings or lens materials on your glasses that either reduce or block out the blue light.
  4. Sunlight is the greatest source of blue light for most people, so wearing good sunglasses are important.

Using a combination of the above treatments will provide the best protection.  Ask your eyecare provider for more information.
