LED technology and retinal damage

The bright, unhealthy light emitted from digital media devices may be adversely affecting your eyes. High-energy visible (HEV) light, commonly referred to as blue light, can cause retinal cell damage and is being studied as a possible cause of macular degeneration.  My office now offers Crizal Prevencia No-Glare lenses to protect your eyes:

Selectively filter out harmful light (Blue-Violet & UV)

Allow beneficial light to pass through (visible light, including Blue-Turquoise)

Maintain excellent transparency (clear No-Glare lens) for optimal vision at all times

LED technology in smart phones, tablets and other similar devices emits an intense bright, blue light. This distracting light causes other objects in your surrounding view to go in and out of focus. To correct this many of us will begin squinting. This is due in part because people tend to hold their mobile devices between two & nine inches closer to their eyes than they would printed reading material. The closer range causes strain on your eyes.

This is especially true for people who wear corrective eyewear or contact lenses. They are more likely to experience digital stress, as their prescription lenses may not have been designed for the mid-range distances of digital devices.

Please contact our office @ 708-686-5266 to learn how your eyes and safety glasses can start using Crizal Prevencia.


...  an often overlooked essential part of eyeglasses for some prescriptions is adding an anti-reflective coating. Just an expensive add on you say? What if I explained that with an anti reflective coating on your lenses; it is the difference between seeing 20/20 versus 20/30. You wouldn't have to live day after day with the eye fatigue associated with computers, whiteboards, and lighting. And I could demonstrate that your eyes recover a full 5 seconds faster from headlight glare with anti reflective coated lenses. That means your improved reaction time can help you stop your vehicle 20+ feet sooner. Take a minute to examine the information below.....


The 2nd highest ranked employee complaint concerns glare. Glare not only reduces employee comfort; but employee productivity. And quite possibly compromise their health and safety. 3 specific conditions can be identified as caused by glare…..


Sources for this condition include light reflected off a computer monitor and paper documents, from unshaded windows, and the intensity of overhead lighting. Night time drivers are distracted by oncoming traffic's brilliant headlights. Employees who fall into the following categories will all be more sensitive to glare’s effects: those with light colored eyes (such as blue, green, & gray), taking certain prescription and over the counter medications, post refractive surgery, and which have cataracts-diabetes-glaucoma.

  Very Intense sky

Employees who work outside are the most affected by this type of glare and UV rays.



Examples for this type of glare and UV exposure are:  driving into the sun

Employees who work outdoors with highly reflected surfaces such as metal and glass

Maintenance employees on rooftops

Reflections off surfaces covered with snow or water

Glare’s effects on you….

Your eyes become tired and strained which reduces your overall visual accuracy. Your eyes are forced in many of instances of glare, to compensate by squinting. Your vision can become blurred and the ability to judge various contrasts is reduced.

                                                                Remedies for glare....

Distraction glare can be minimized for the computer user through proper layout of the office environment. Indirect lighting as a main illumination source with supplemental lighting for work surfaces is more effective than bare bulbs suspended from the ceiling. Prescription glasses should be made of a polycarbonate material (which has a tint and UV filter included). Prescriptions glasses users will also benefit greatly from a significant reduction in glare's effects when an antireflective coating is added to the lens surface. Non prescription safety eyewear should contain a mirror coating.

Glare caused by bright  intense sunlight can be reduced for prescription glasses users by incorporating Transitions, or a solid grey tint (at level 3 darkness) Non prescription safety eyewear should have a solid grey tint at level 3 darkness.

Blinding effects can be controlled for safety glass users, both prescription and Plano, by adding a mirror coating to the front surface of a solid grey G-15 tinted lens.

In conclusion; we all have experienced glare firsthand and know; is quite bothersome. Without a doubt we are more comfortable because of antiglare measures. We see more accurately and in turn are able to address our job responsibilities with greater productivity. And when your vision is protected from the harmful affects of glare: you are safer whether its from poor ergonomics, damage to sensitive internal workings of the eye, or unsafe job execution.
