Blue Light Blocking Lenses in Bandera

What is Blue Light?

The sun is a natural source of blue light. In fact, this is the reason the sky appears blue to our eyes. Light exists in a spectrum of color and some of these are filtered out by our eyes. Blue light, however, isn’t filtered as easily. This means that more blue light enters the retina, compared to other colors.

Digital devices are also a source of blue light. This is why blue light glasses are often known as computer glasses. On average, those who work in an office spend an average of 1,700 hours a year looking at their computer screens. Cell phones and tablets also fall under this spectrum, so your eyes receive a lot of blue light exposure from all three devices.

What are Blue Light Blocking Glasses?

Blue light-blocking glasses are designed to reduce your eyes to the exposure to blue light. There are several types of blue light-blocking glasses. Clear or yellow lenses block a narrow spectrum of blue light, without distorting the colors you see on your screen. Red or orange-tinted lenses block more blue light, but they can distort the colors you see on your screen.

Do Blue Light Blocking Glasses Work?

Blue light-blocking eyeglasses can have various benefits if you utilize them daily or often, which exposes you to a significant amount of blue light. With a pair of these, it’s easy to block some of the exposure of the blue light and they can also help you with a better night’s sleep since they could increase melatonin. Our doctors can provide you with additional insights on the glasses and advise you on which may be best for you.

Insomnia 

If you suffer from insomnia, these glasses may help. Our bodies know that the sun gives off blue light. When we are exposed to blue light, we are not able to produce as much melatonin, which is the hormone that helps to induces sleep. These days, we use our devices day and night, but the exposure to them can keep us awake, so he blue light glasses can help to block out the light and allow for some more rest.

Computer Vision Syndrome 

Computer vision syndrome occurs when you encounter eye strain due to spending a lot of time looking at a screen. Symptoms of the syndrome include dry eyes, blurred vision, and headaches. The blue light emitted by screens is thought to play a role in computer vision syndrome. If you happen to spend the majority of your day in front of a computer, blue light-blocking glasses can be beneficial in helping limit blue light exposure.
