How To Save Your Eyes From The Health Effects Of Harmful Blue Light

Health issues related to protecting our eyes and skin from the harmful UV rays of the sun are of great concern as overexposure to these rays can cause skin cancer and sunburn. However, when it comes to issues related to protecting our eye health another source of light that is another cause for concern is blue light.

What is blue light? This form of light is defined as that part of the light spectrum that emits a high level of energy that is described as visible light. Due to the fact that this form of the light consists of one of the highest forms of energy it reaches deeper into the eyes. Our eyes are more susceptible to this form of light that other forms of light including U.V Rays. Overexposure to this form of light has a negative effect on the Retina of the eyes and is linked to the development of the age related vision disorder called macular degeneration.

What are some sources of this form of light? Various sources of blue light include cell phones, the display screens of computers, flat screen television sets and other digital devices such as tablets and iPads. Here are some of the negative effects of Blue Light on the eyes:

Overexposure May Contribute To Macular Degeneration: Due to the fact that this form of light reaches even deeper into our eyes than U.V rays, and other forms of visible light, overexposure to it is associated with damage to the light-sensitive cells of the retina and mimics the symptoms of macular degeneration.

Blue Light Leads To Digital Eye Strain: Due to the fact that this type of light does not emit focused energy but scattered energy, the eyes are more susceptible to this form of light energy. Many electronic devices and digital devices emit a significant amount of blue light, and therefore, this scattered high energy can irritate the visual system and cause digital eye strain.

What can be done to reduce the effects of this form of light so that we can protect our eye health? Health experts advise that you should wear computer glasses with yellow tinted lenses as a remedy to this problem. This reduces the discomfort associated with staring at computers for prolonged periods of time while limiting our exposure to this kind of light to safer levels.

In terms of reducing exposure to harmful blue light on technological devices, a blue light filter is recommended. These are available in retail stores and some examples include illumi-shield and Eye safe Filters. Eye exercises that reduce eye strain are also helpful in reducing this problem. For instance, when staring at digital devices take frequent periodic breaks to look away from your close up work and focus on a distant object about 10 to 20 feet away.

Overexposure to blue light can have harmful effects on the eyes. However, there are safety measures that you can take to eliminate this problem. These include the use of filters on digital devices, computer eyeglasses and the practice of eye relaxation techniques. Ultimately, by applying these common sense safety guidelines we can eliminate the eye problems associated with exposure to harmful blue light.
