Technology and Blue Light Overload

by Blog

Do you find yourself spending more time in front of your computer?  Working from home, remote learning for your kids, texting, social media, TV – we never seem to be able to take a break from technology.  All that blue light can cause a number of symptoms.  The artificial blue light emitted from our smart devices is high-energy and can have some long term effects on our vision.

Blue light is all around us, there are both natural blue light and artificial blue light.  Natural blue light comes from the sun. It is a short wavelength of visible blue light and high in energy.  Artificial blue light also a short wavelength of visible blue light is high-energy and remains high all the time. Prolonged exposure to blue light has shown to damage the retina, the part of the eye that detects qualities such as color and light intensity.

Blue light comes primarily from the sun and artificial light sources like digital screens and fluorescent lights. Blue light could be the reason your kids find it difficult to fall asleep at night, struggle with concentration, and develop eye-strain.

Ever wonder why you can’t go to sleep after scrolling on social media, checking email, or texting?  Did you know that blue light disrupts your circadian rhythm by reducing melatonin production? This is the hormone that tells your brain when it’s time to sleep. Blue light tricks your body into thinking it is daytime.

Other symptoms include:

  • Headaches/Migraines
  • Eye Strain
  • Blurry Vision
  • Dry Eyes
  • Inability to focus
  • Disruptive Sleep Patterns

Although there are many alternatives to blue light blocking, the most effective is blue light protection eyewear glasses because it provides protection all day. Just think about it, how quickly do you switch from looking at your computer screen to your phone or television to take a break? How about the LED lights at the supermarket or workplace? We can’t escape blue light, but we can surely decrease our exposure to it.

Up Your Game to Better Eye Health

by Blog

No matter what age you are, taking care of your eyes should in your game plan for optimal health.  Often patients take their eyesight for granted until they begin having problems with their vision.  Keeping up with annual checkups is as important as your annual physical.

When day-to-day activities become challenging, that will trigger a call for an eye appointment.  Having good vision and healthy eyes may determine your ability to remain independent and self-sufficient.  Here are some tips to maintain optimal eye health.

EAT A BALANCED DIET

As part of your healthy diet, choose foods rich in antioxidants, like Vitamins A and C; foods like leafy, green vegetables, and fish.  Many foods – especially fatty fish such as salmon – contain essential omega-3 fatty acids that are important to the health of the macula, the part of the eye responsible for central vision.  As the gardening season gets underway, be sure those green vegetables are part of your crop.  High-fat diets can also cause deposits that constrict blood flow in the arteries. The eyes are especially sensitive to this, given the small size of the blood vessels that feed them.

EXERCISE

Not only is exercise good for the body, but the increased blood circulation improves the oxygen level to the eyes.

CATCH YOUR ZZZZs

A good night’s sleep allows your eyes to replenish the supply of natural tears.  Go too long without enough sleep, and you might start getting twitchy eyelids, eye strain, or dry eye.

STOP SMOKING

Smoking increases the risk of eye diseases such as cataracts and age-related macular degeneration.  Tobacco smoke worsens dry eye.

WASH YOUR HANDS

Maintaining good hygiene practices will help to prevent eye infection.  Always remove makeup before going to bed.    Bacteria will form from your eyelashes and requires daily eyelid hygiene. Like brushing your teeth, your eyelids need daily care.  Hot compresses help keep tear-producing glands working at top efficiency.

BREAK OUT THE SUNGLASSES

Exposure to ultraviolet UV light raises the risk of eye diseases, including cataracts, fleshy growths on the eye, and cancer.

DEVICES AND BLUE LIGHT OVERLOAD

Digital devices have become appendages – TV, computer, tablets, ipads, and smartphones.  Between work and personal use, we can’t get away from technology.  These devices are exposing your eyes to high energy blue light. It’s called blue light because the wavelengths emitted are near the bluer part of the spectrum.  To avoid digital eye strain, take a break every 20 minutes, blink often, keep your computer screen within 20-24 inches of your eye, and adjust the lighting to minimize glare.

The good news is most vision loss is preventable. During a comprehensive eye exam at Bissell Eye Care, dilation and our state-of-the-art technology allow us to look at the overall health of your eyes.    During these exams, we may discover conditions that affect your eyes.   In addition, an underlying medical condition in your overall general health could be uncovered.  This will ultimately help your primary care provider enhance your overall health and wellness program.
