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?

What are conditions that can affect a child’s vision and the potential for learning? What is Amblyopia? What is Strabismus? What about Convergence Insufficiency? These are serious conditions of a child’s eye that need addressed. Did you know that 80% of learning comes through vision? The proverb that states, ”A picture is worth a thousand words” is true! But what if a child cannot visually see or process those words?

Let’s explore Amblyopia , or “lazy eye”. It affects 3-5% of the population, enough that the federal government funded children’s yearly eye exams into the Accountable Care Act or ObamaCare health initiative. Amblyopia occurs when the anatomical structure of the eye is normal, but the “brain -eye connection” is malfunctioning. In other words, it is like plugging in your computer to the outlet and the power never gets to the computer all the way.

Amblyopia need to be caught early in life, in fact if it is not caught and treated early (before age 8) it can lead to permanent vision impairment. Correction with glasses or contacts and patching the good eye daily are ways it is treated. Most eye doctors agree that the first exam should take place in the first year of life. Early detection is a key.

Strabismus is a condition that causes an eye to turn in (esotropia), out (exotropia), or vertically. It can be treated with glasses or contacts, and if needed surgery. Vision therapy or strategic eye exercises prescribed by a doctor can also improve this condition. In fact, vision therapy is the treatment of choice for Convergence Insufficiency.

When we read, our brain tells our eyes to turn in to a comfortable reading posture. In Convergence Insufficiency, the brain tells the eyes to turn in, but they instead turn out, causing tremendous strain on that child’s eye for reading. Another tell tale sign of this condition is the inability to cross your eyes when a target approaches. The practitioner will see instead, that one of the eyes kicks out as the near target approaches. This condition can be treated with reading glasses or contacts, and eye exercises that teach the muscles of the eye to align properly during reading.

It is important to understand the pediatric eye and all the treatments that can be implemented to augment the learning process. Preventative care in the form of early eye examinations can mean the difference between reading properly or struggling badly in a child’s learning. Remember, a young child can’t tell you if they have a vision impairment or not. For the success of the child: be proactive in encouraging exams in the first year of life and beyond.
