May is Healthy Vision Month.  There are lots of things that you can do to protect your and ensure healthy vision such as exercising , eating healthy, regular eye exams and of course wearing sun protection such as our Jonathan Paul Fitovers. However, there is a new concern with our increasing use of smartphones, tablets and computer screens: Blue Light.

We cover a few of the big questions concerning Blue Light and what it means for you.

What is Blue Light?

Simply put, Blue light is a color in the “visible light spectrum” that can be seen by the human eye. Blue Light can be found everywhere including the sun, digital screens (TVs, computers, laptops, smart phones and tablets), fluorescent and LED lighting.

 


The component of light in the blue-violet band between 390 and 500 nm is known as high-energy visible (HEV) light. Wavelengths between 390 and 440 nm are seen as particularly critical.

What are the long-term effects of blue light exposure?

At this time there aren’t any long term studies linking the HEV light from our smart devices to degeneration of the human retina partly due to that face that these devices are relatively new. However, there are scientific sources strongly supporting a correlation.

EM007Y-F&OAs the saying go, there is too much of a good thing! Too much light in the UV and blue violet scale can be damaging to our eyes. It can lead to painful inflammation of the conjunctiva and cornea and also damage the eye’s crystalline lens (e.g., cataracts) and retina (macular degeneration).

We think that it’s best to err on the side of caution. Be sure to take breaks from your devices throughout the day and wear protective eye wear that can block HEV.

Does Jonathan Paul Fitovers block Blue Light?

Yes, our  yellow lens is polarized and allows 30.76% of visible light through the lens. It blocks 96.44% of HEV Blue Light (High Energy Visible Light) between 400 and 500nm. HEV light is considered most concentrated between 410 and 460nm
