How To Keep Your Eyes Healthy – Even If You Already Wear Prescription Glasses

How To Keep Your Eyes Healthy – Even If You Already Wear Prescription Glasses

February 5, 2022 Off By Jennie Cox

For years, doctors have been telling us to worry about the sun causing skin cancer and eye damage. Today, we also have to worry about blue light. People of all ages spend time on the computer, playing video games, and staring at their cellphones and tablets, and these activities can be harmful because your devices project blue light. You can shop for blue light filter glasses at Blue Optical to improve your vision, comfort, and your overall health.


What Is Blue Light?

We see a wide range of colors, and they all have a place on the color spectrum. Blue light is at the lower end of the spectrum and contains shorter wavelengths that emit more energy that can be damaging to your eyes.


Is Blue Light Harmful?

In small doses, blue light is relatively harmless; however, it can be harmful in large doses. If you spend most of the day staring at a screen, blue light can have negative effects, including:


Eye Strain: Eyestrain is common when reading a book or doing closeup work for too long; however, it can occur much faster when you stare at a digital device for hours. Eyestrain causes a number of symptoms, including:


  • Sore, tired or itchy eyes
  • Dry or watery eyes
  • Headaches
  • Double vision
  • Increased sensitivity to light
  • Struggling to keep your eyes open


Eye disease: Our eyes weren’t built for the digital age, and they weren’t designed to filter blue light. Spending too much time in front of the blue light emitted from your digital devices can result in cataracts, which often require surgery. Extended exposure to blue light can also cause macular degeneration, which is a condition that causes permanent loss of your central vision, and there is no cure.


Sleep disturbances: If you don’t get seven to eight hours of sleep a night, it can be challenging to get through the day. In addition, a lack of sleep can cause high blood pressure, obesity, depression, a weakened immune system, and lower sex drive.


Overexposure to blue light can cause sleep disturbances. Your circadian rhythm is your sleep/wake cycle, and it tells you when to wake up and when to go to sleep. The sun emits blue light, which helps you get up in the morning. If you spend your evening in front of digital devices and are overexposed to blue light, your body will think it is time to stay awake when it is really time to sleep. This can make it difficult to fall asleep at night, making getting seven to eight hours of sleep each night challenging.


Increased risk for cancer: Studies have shown that overexposure to blue light can increase your risk for cancer. One study found that people who work the night shift in front of blue light are at greater risk for prostate, breast, and colorectal cancer.


Preventing Issues Caused By Blue Light

Unfortunately, it is almost impossible to avoid blue light in today’s technological world. We rely on computers and cellphones to get things done and connect with others. In addition, we rely on technology for entertainment, including scrolling through social media, playing video games, and reading books on your cellphone or tablet. Fortunately, there are ways you can prevent issues caused by blue light.


Taking frequent breaks from technology can help. The same is true if you avoid using your devices a few hours before bed. The best way to prevent these issues is with blue light filtering glasses. These glasses contain a blue light filter capable of blocking 50 to 99 percent of the blue light emitted from your devices.


If you wear glasses to treat nearsightedness, farsightedness, or astigmatism, your eye doctor can add a blue light filter to the lenses. If you don’t wear glasses, your eye doctor can prescribe a pair of non-prescription glasses with a blue light filter.


When you start wearing the glasses, you may see a difference right away. You will see that you can spend more time in front of your digital devices without developing eyestrain, and you could find it easier to fall asleep at night.


If you spend a large part of the day in front of your digital devices, it is best to look into getting blue light filter glasses now before you begin experiencing more severe symptoms. Everyone is affected by blue light, and it can negatively affect you now, even if you haven’t experienced any symptoms yet.
