Why You Should Wear Blue Eye Glasses
We live in the computer age and this means we are surrounded by screens. Some of these screens include smart phone screens and screens from a variety of devices like tablets, iPads and the like. As people spend long hours on these devices, they run a risk of eye damage because most of these screens emit blue light. Since our eyes are not naturally protected against exposure to blue light, it follows that we need blue light glasses to protect our eyes. However, before discussing the benefits of blue light glasses, it is perfectly in order to talk about blue light glasses, what they are how they can harm your eyes.
Understanding Blue Light Glasses
Blue light is just one out of many forms of light in the light spectrum. Other forms include yellow light, white light, indigo, orange, yellow and violet. However, blue light receives plenty of bad press because of its connection to digital devices. Computers, smart phones, iPad and the like, all these things emit blue light. There are also traces of blue light in the sun’s rays. However, blue light from the sun does not receive as much bad press as blue light from electronic devices do. There are cogent reasons for this.
Why Blue Light Receives Bad Press
Blue light from digital devices receives bad press for a number of reasons. First off, people spend many hours just looking at their phones, laptops and other devices. This means that the blue lights are more likely to harm the eyes because of the number of hours people spend in front of these devices. Again, blue light has a relatively short wavelength and this means it can easily penetrate the eyes. Experts in ophthalmology claim that blue light can even pass through the cornea and the lens and get to the retina. According to experts, this could lead to retina damage and this is something you don’t need. In simple English, excessive exposure to blue light can lead to eye damage and aggravate macular degeneration. This is why you need to protect your eyes from blue lights.
Benefits of Wearing Blue Light Glasses
Among other benefits, blue light glasses protect your eyes by blocking out the harmful blue lights. This stops blue light rays from getting into your lens and getting to your retina. According to Dana from Blue Optical, “blue eye glasses reduce glare and this protects your eyes when you are working with a computer or using your smart phone”. Again, these glasses reduce eye strain, helps you get better sleep and generally improves eye health. Other benefits of blue eye glasses include the fact that these glasses can relieve digital eyestrain symptoms including headaches, blurred vision and even dry eyes.
Caveat
Now, some experts claim that blue eye glasses are a bit over-hyped. According to the experts in this category, there is little scientific evidence to support some of the claims made by advocates of blue eye glasses. However, this writer does not agree with these so-called experts. In any case, it is always better to err on the side of caution. If it turns out that blue eye glasses are overrated people who wear these glasses have not lost anything. However, if it turns out that these glasses have all the benefits they are touted to have, not wearing these glasses can be an all-time bad decision. Final word: Use blue light glasses because they just might save your eyes.
