Block the Blue Light

The truth is, blue light isn’t all bad. It shouldn’t be blocked at all times. It can help memory, boost alertness, and elevate your mood! Still, the eye cannot take blue light all day long and it can easily contribute to eye strain especially when it is coming from computer screens and tablets and cellphones.

These days, we’re working, learning, and relaxing in front of screens emitting blue light all throughout the day—and night. Even your average indoor lightbulb can give off blue light.

You’re probably wondering. Okay, but what is blue light anyway?

Blue light is the highest energy visible light on the UV spectrum, and before the advent of technology, the sun was our only significant source of blue light. Problems arise, however, with the amount of blue light to which we are exposing our brains and bodies, potentially causing undue stress to our eyes and even making it hard to sleep at night.

There are a few ways to avoid this strain. First, let us introduce you to one of the best options on the list: blue light blocking lenses.

What are blue light blocking lenses?

Good question. Glasses equipped with lenses with blue light protection are a simple solution to combat the symptoms caused by increased screen time. The technology in these lenses has a subtle tint that softens harsh blue light rays as they pass through, reducing the amount of blue light to which the wearer’s eyes are exposed. They aren’t heavy or thick and can be made without a prescription attached to them. They can be made to fit adults, teens and children and are safe for all to wear. All blue light blocking glasses aren’t made the same. They can be made to block a certain percentage of blue light. How much you decide to block, well, that is up to you. Give our practice a call and we will gladly talk you through your options!

What else can I do to block blue light?

While you won’t be able to block it without the correct lens as your shield, you can still manage it.

When working at a computer, for example, you’re often looking up and down, from screen to paper, and your eyes are moving around and refocusing time after time. This is where the 20-20-20 rule can come into play. For every 20 minutes you’re in front of a screen, turn your head and look at something at least 20 feet away for 20 seconds. Just, give your eyes a break.

Another option: simply lower the brightness. The display settings for your screen on your phone or computer allow you to adjust the amount of light seeping from the screen. If your screen looks like a light source, lower the brightness. If your screen looks dull and a bit too dark, it’s okay and probably for the best to brighten it up. A dull screen can also strain your eyes.

Bottom line, protect your eyes the best way you can and remember that we are here to help! Looking to get a pair of blue light protection glasses that fit your lifestyle and your budget?

Have you ever tried to look into a room by looking into the keyhole? You only see part of the room... right? Well, that is what it would be like for your eye doctor to look into your eye through an undilated pupil. They would only see a partial view of your retina, with the possibility of missing vital information about the health of your eyes.

That is why it is important to have your eyes dilated for your exam, whether through traditional eyedrops which will wear off in several hours, or through new technology that can take a panoramic digital picture of the inside of your eye without dilation. Either method will provide your eye care professional valuable insight into your ocular and systemic health. Here are the top 5 reasons to have your full retina evaluated through a dilated view:

  1. To have the health of your retina evaluated. The retina is like the film of the camera of your eye that processes the vision accurately. The central retina contains cones for your color and detail vision, and the peripheral outer retina contains rods for your night vision.
  2. To detect ocular and systemic diseases early. Ophthalmic diseases such as glaucoma, and macular degeneration need to be caught early and treated for optimum vision. Furthermore, the saying “the eyes are the window to the soul”, is true. Systemic diseases such as diabetes, hypertension, and high cholesterol can be detected sometimes before they show up in the rest of your body. Your eye care practitioner can coordinate care with your family physician to ensure optimal health.
  3. Dilation can help your doctor get an accurate glasses prescription, especially for children. In the pediatric population the eye muscle can contract extensively more than adults, so their muscles work harder, thus fatiguing the visual system. Dilated exams can ensure a more accurate glasses prescription.
  4. To give you peace of mind, and also provide a baseline for your eye doctor for future examinations. If you move or relocate with a new doctor, have your records transferred for maximum eye health benefits.
  5. Lastly.......A dilated exam could save your life! Numerous reports show that cancers such as lung, or breast cancer metasticize to the eye and can be detected in the retina during an eye exam. In children up to age 15, there is a 3% chance of an aggressive cancer in the eye called Retinoblastoma. Symptoms of this in a child’s eye are a “White Pupil “ reflex in a photo. When detected, this cancer can be caught early by dilating the eye.

Overall, the benefits far outweigh the risks in a dilation of the eyes. The side effects are blurry vision, and sensitivity to light for several hours following the exam (so bring a driver with you). The benefits, however, could be larger than life!
