Dr Michael Lange founder of Lange Eye Care and Associates  and Fortifeye Vitamins discusses how Blue light may be harmful to the eyes and entire body.  11/12/14

The High energy visible ( HEV) spectrum from about 380-500 nm is the blue light. This blue light is very important to our health during the day time. This blue light is responsible for us being alert, full of energy and cognitively functioning well during the day. However when it gets dark blue light can hinder us.  Blue light is not only out doors it is found indoors as well.  Many of the day-to-day items that we use like television, computers, tablets , cell phones and indoor lighting  emit this blue light.  New University based studies  indicate Blue -Violet light exposure in the evening  may cause  suppression of melatonin. Melatonin is an antioxidant responsible for a good nights sleep and good health.  When melatonin levels drop our biological clock ( circadian rhythm) is interfered with.   Theses lower levels of melatonin may cause sleep deprivation and other health issues.   It is crucial that we minimize our exposure to blue- violoet  light at night-time. How can we do this? well  simply by  adopting a rule of no tv, tablets , computer, smart phone three hours before bed will help dramatically. However realistically this may not work.  Another great option is to wear glasses that filter the blue light. “Blue light defense ” is becoming  the buzz word among eye care providers.   Many blue filtering lenses are now available that you can wear in the evening when you are working on the computer or watching television.  Dr Michael Lange says talk with your local optometrist to see which particular blue filtering lens is best for you.  Many companies now manufacture blue filtering lenses that can be purchased through a local optical. Dr Lange recommends a brand new  almost completely clear blue filtering lens in all Lange Eye Care locations called Blue Light Defense.  .  Dr  Michael Lange also recommends  eating more foods that are high in two carotenoids lutein and zeaxanthin.  These carotenoids are found in spinach , orange bell peppers and gogi berries.   There are also many supplements on the market that contain these nutrients along with many other beneficial nutrients.  Dr Lange has developed a supplement called Fortifeye Focus  that contains a mixture of astaxanthin, lutein and zeaxanthin.  This formula was developed to give the nutrients necessary to decrease focusing strain while on the computer and  help absorb the harmful blue light .    Dr Lange recommends everyone at any age wear blue filtering lenses especially at night and eat plenty of  dark green leafy vegetables and orange bell peppers.  If you cant eat these frequently then he recommends supplementing with the Fortifeye Focus or Fortifeye Focus for kids ( coming July 2015) or a similar brand.  Fortifeye Focus Chewie ( for kids and adults) is all non gmo natural delicious chewie containing  lutein, zeaxanthin isomers and astaxanthin.    Learn more  at , or  to learn more about the latest blue filterning lens called Blue Light Defense go to

    Can a person wearing the Blue Light Defense lenses see the color blue in blue objects, blue sky, blue clothing, blue cars, etc.?

      Yes blue light defense lenses block only the harmful blue light not all the blue light. Since it is a selective blue filter it allows u to see all colors including blue .
