Blue light is the type of light with the shortest wavelength and highest energy. It’s everywhere! Although many people associate blue light with technology, the sun is the primary source of these rays.

Many human-made devices also emit blue light, and in recent years, the time individuals are spending on these devices has increased dramatically.

Key Points

About Blue Light

The anterior structure of your eye, made up of the cornea and lens, is very effective at blocking UV rays from reaching the retina, located at the back of your eye. However, blue light cannot be filtered naturally by the eye and passes through the cornea and reaches your retina. Your retina’s continued exposure to these harmful rays can result in a higher risk of developing macular degeneration over time, and eventually, permanent vision loss.

Not all blue light is bad, though. Some exposure is proven to be good for your health. Blue light–taken in appropriate amounts–can boost alertness, improve memory and cognitive functions, and elevate your mood.

Symptoms of Overexposure

Some of the most notable signs of overexposure are:

  • Eye Strain
  • Headaches and Migraines
  • Blurry Vision
  • Dry Eyes
  • Inability to Focus
  • Disruptions in Sleep Patterns

Protecting Your Eyes

Digital devices aren’t going anywhere, so it’s essential to ensure that you are taking preemptive steps to protect your eyes from blue light. With electronic devices, consider these few tips to reduce the harmful rays reaching your retina.

  • Hold your Device at an Angle
  • Wear Blue Light Blocking Glasses
  • Use a Screen Filter
  • Install a Blue Light Blocking App
  • Take Advantage of “Comfort View” Settings

Ready to take protection to the next level? Ask us about computer eyewear! Computer eyewear will drastically reduce eye strain by filtering emitted light before it reaches your eyes. Many electronic devices are starting to offer apps or different settings that are intended to lessen the amount of blue light that is emitted so it’s less harsh on your eyes. While these settings don’t necessarily protect your eyes from the blue light, it does cut down on eye strain considerably by lessening the contrast.

Do you have more questions about how you can protect your eyes? Stop by our office or give us a call and we would be more than happy to answer your questions!

COVID-19 Office Reopening

We are scheduling routine eye exams again.  We have missed our patients, and are very excited to safely get back into the swing of things after our temporary pause due to Covid-19.  Give us a call at 918-745-9700.

Rest assured, we have developed new office protocols to protect the health and safety of our patients and our staff.  For the time being, we will be lengthening the time between patient appointments with the goal of having only one patient in the office at a time.  We will check the temperature of every person entering our office.  Thorough disinfection will take place after every patient.  We will be wearing protective equipment and ask all patients to wear face coverings into the office.  We are asking that patients do not bring any family or guests with them into the office (unless the patient is a minor or requires a caregiver).  Please make appointments for glasses adjustments and dispensing to assure social distancing is observed.  Lastly, if you or a member of your household is ill, please reschedule your appointment.

We will be monitoring conditions and recommendations and will update our policies accordingly.

Thank you,

Andrea Dudley, OD and staff
