Protection from Blue Light

What is Blue Light?

Blue light is an important consideration when discussing woman reading a tablet in Kennett Squarethe need for glasses. Dr. Ganly of Ganly Vision Care explains, “High energy Blue light is a component of visible light and it surrounds us everywhere we go. But, it also is more prominent on computer screens, televisions and smart phones, and has been known to cause eyestrain, headaches and fatigue. Even more alarming, recent studies also point to growing evidence that blue light exposure has the potential to significantly increase a person’s risk of Macular Degeneration over time. It has also been shown to affect our melatonin levels which are important in regulating our sleep patterns. Fortunately, the last few years have seen significant strides in blue light blocking technologies that can be widely applied to make glasses even more effective at protecting your eyes.”
Do you often experience blurred vision, eyestrain or headaches after being on your computer or smart phone for an extended amount of time? If so, you may be experiencing a condition known as Computer Vision Syndrome. Fortunately, eye doctors have developed a special type of eyeglasses, known as computer glasses, that are made specifically to address the unique needs of those who are on the computer or other electronic devices for extended periods of time each day.

Benefits of Computer Glasses

In explaining the benefits of computer glasses, Dr. Ganly first points out, “Usually, computer screens are positioned around 20-26 inches from your eyes, in what is commonly referred to as your ‘intermediate’ zone of vision. Because traditional eyeglasses are not made in a way that is conducive to intermediate viewing of the type required by computer work, blurred vision, eyestrain and headaches often result. By comparison, computer glasses are specifically made to emphasize comfortable intermediate viewing, helping your eyes more easily focus on the computer screen with less effort and making computer viewing over an extended period of time noticeably more comfortable.”
Computer glasses are often equipped with specialty lenses, that are meant to reduce or eliminate many of the harmful side effects linked to increased time in front of computers and other electronic devices. This is accomplished by selectively filtering out blue light, which enhances visual comfort and minimizes eyestrain. At the same time, these lenses allow non-harmful light to pass through, allowing for the clearest vision possible.
Computer glasses are an absolute necessity for maintaining both your short term visual comfort and long term visual health as you work and play in a world increasingly dominated by computers and smart phones.
