How Does Blue Light Affect Your Eyes?

As people spend more time staring blankly at computer monitors and other static-prone electronic equipment, they are turning towards blue light glasses as a solution to dry and sore eyes.

So, how does light blue glasses help improve your vision? Basically, your eyes must work harder than normal in order to see clearly through the frosted screen on your computer monitor or TV. The human eye has a natural aversion to nearsightedness or farsightedness, which basically means the moment you look at something that is close up your eyes start to adjust. This natural reaction only becomes more intense as you near the edges of a computer screen or near a bright light source like the sun or a flash. If you’re looking at something far away your eyes will keep track of the movement just fine but your central vision or processing of the information will be impaired. This is what causes the common problems with computer users called computer vision or blurring of the vision.

There are some obvious symptoms of eye strain like headaches, fatigue, dry eyes, auras and even trouble focusing. However, these symptoms do not necessarily mean that you are suffering from computer vision or blurring of the vision. They may just be caused by the type of work you do or the environment you work in. So, to help determine if you are having visual strain the medical history of the patient is often helpful. If you happen to notice sudden or severe eye strain accompanied by other symptoms such as seeing halos around lights, having trouble seeing clearly at night or trouble focusing at night after using the computer for a while, then it is time to check into computer eyeglass wear or light blue glasses.

Many prescription eyeglass users experience trouble focusing at night because they either work too long at night or their work involves a lot of computer activity. In order to make sure that the visual clarity is not severely affected because of work or computer use, many health care professionals recommend that their patients start using blue light blocking glasses or corrective lenses right before bedtime. The reason why blue light eyeglasses or corrective lenses are recommended for people who need to work late into the night or work in a very dark environment is because it helps to alleviate some of the strain that occurs when we go to bed. For people who work in a very bright environment, they could use sunglasses or even simple reading glasses to maintain the amount of light they absorb during the daytime.

As we age, changes occur in the amount of daylight we can observe and the amount of blue light our eyes are capable of seeing. The amount of light we can see also depends on the amount of strain our eyes have to carry, as well as the amount of light our eyes can tolerate. There are many products available today that help to relieve some of these challenges, allowing you to work longer and stay awake without suffering from visible light eye strain.

A great example of technology that helps you fight against visible light rays and keep your eyes from becoming strained is progressive lenses. The biggest difference between the different kinds of lenses available is how the light rays are refracted. Progressive lenses provide a smooth transition from light to shadow, as well as allow you to transition from direct sunlight to varying amounts of light, depending on what you are doing.

Some of these blue light rays can enter your eyes and cause you to become light sensitive. This is why you will often times see people in the sun with dark circles under their eyes. They experience what is called the “snow effect” when standing under a large amount of sunlight, because the amount of visible light their eyes are exposed to is greater than what they can tolerate. When this happens, their vision starts to blur until their eyes become accustomed to the lack of light, and they develop light sensitivity.

The best way to combat this problem is to wear sunglasses, or at least wear a filter that filters out blue light before going outdoors. You can also buy blue light blocking glasses if you don’t want to be so dependent on artificial light. While you might not think blue light blocking sunglasses would actually help you see better, studies have shown that they do reduce the amount of blue light your eyes absorb, allowing you to see better throughout the day. So, you might not think it’s an effective solution to how does the blue light affect your eyes, but the truth is it could save your sight for good!
