 Dr Michael Lange discusses the importance of filtering the blue light. Blue light defense and blue light damage is becoming a main stream topic in the eye care industry.  Filtering  the Blue Light is proving to be good for the eyes and entire body.   Minimizing Blue Light Damage should be addressed by all health care providers and parents.  

The high energy visible spectrum (HEV) or Blue light is a topic that is being studied and lectured about extensively . This is  the wave length  between 390-500 nm.  Blue light is emitted by the sun , computers, Smart phones, television, tablets, and many types of lighting.  Eye care providers are now recommending blue filtering lenses to their patients.   www.bluelightdefense.com

Blue light does have some beneficial effects and is not all bad. The blue light that comes from the sun  during  the daytime has positive biological effects on the human body.  Exposure to Blue light during the day time regulates our internal biological clock and maintains a normal circadian rhythm allowing us so get a good night sleep.  Blue light exposure during the day keeps our brain functioning well, keeps us alert and helps maintain psychologically well-being.

When the sun sets the Human body is supposed to start to wind down ,relax and get a good nights sleep.  In today’s society this isn’t  happening do to the pro longed exposure in the evening to various devices that emit blue light.   We are using digital devices like smart phones, computers, tablets and even television that are  emitting the  potentially harmful blue light rays .   These frequencies  of blue light may interfere  with the human  biological clock and disrupt sleep patterns.  A good nights sleep is crucial for overall health.

Blue Light exposure to the eye is becoming more and more prevalent  since the majority of us are using digital devices in our daily routines.   Studies  indicate that chronic exposure to blue light  may increase our risk of macular degeneration.  Prolonged exposure of blue light from near work on computers, smart phones and tablets increases eye strain , fatigue and dry eye symptomatology.  One of the main culprits  for computer vision syndrome (CVS)  is prolonged near point use on computers that emit blue light.

Many lens companies are now selling blue light protection  lenses that filter this blue light.  All blue filtering lenses are not the same. Some lenses have certain tints that are used to absorb some of this blue light. These lenses can be yellow, orange or purple in color.  Some companies are using a coating to absorb the blue light and some are actually putting this filtering technology into the lens monomer so it is throughout the entire lens.  Many lens companies are filtering only a small percent of the harmful blue light and some are filtering close to 100% of specific harmful rays.

I recommend  looking for certain specific characteristics when shopping for blue lens blocking technology.  1. look for a lens that is as close to being clear as possible, lenses that have a tint to them will block some of the transmission of light and decrease night vision, tinted lenses can also be cosmetically un appealing .  2.  make sure the blue filtering properties are in the actual lens material ( monomer) and not a coating that can  flake off and scratch .  3.  ask what percent of blue light  and what wave lengths are actually being filtered.   4.  check the lens for your self with a blue laser, a good blue filtering lens will block the majority of a blue laser from going thru the lens, this a simple test that will rule out much of the competition.  If your lens meets these 4 criteria you will minimize the blue light exposure  to your eyes and entire body.

A  new generation lens I have been using with patients with incredible results since 11/14  that will qualify for all 4  of the characteristics from above  is:   Blue Light Defense  and Blue Light Extreme.  These lenses come in a variety of materials and designs.  This is brand new technology that is just starting to emerge in the eye care centers throughout the country and wont become mainstream probably   until the Fall of 2015.

The science is pretty conclusive that we need to filter this blue light especially in the evening when working on  computer, tablet, smart phones or watching tv. Relatively new research has been directed at filtering the  the blue /violet light .  This research also sugests that around 411 nm is one of the worse frequencies of blue/violet light for the retina.   Blue Light Defense filters close to 99% of the waves between 400-420nm.  and then filters smaller amounts up  500nm  Take control of your future health and your children’s future health by investing in these new blue light defense lenses.

  2. I have been wearing the Blue Light Defense lens for about one month now thanks to my optometrist recommendation. I am on a computer eight hrs a day at work and three to four hrs a day at home. I have noticed a significant reduction in eye fatigue, my eyes do not feel worn out by the end of the day. However the number one benefit is I actually get a much better night of sleep. I can honestly say these lenses have made a big difference in my life!

  3. Hi Dr Lange. I did get the plus,2 readers in the blue light defense . You asked me to let you know,how they are working. I was kind of skeptical at first but oh my goodness was I surprised at the difference. I don’t feel the “heat” coming from the computer screen that I work in front of all day. And I really am dreaming again. It’s truly amazing. I would not have believd it if I didnt’t experience for myself. I’m really glad I invested in them. Thank you again. Looking forward to the new protein drink from Fortifeye Vitamins.
