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?

Lyme disease is an infection that is caused by a spirochete (a type of microorganism) called Borrelia burgdorferi. It is transmitted to humans by the bite of a deer tick.

The disease has a strong geographical incidence, being highly concentrated in the Northeast United States and now also has a high incidence in Minnesota and Wisconsin.

Lyme disease was first discovered in Old Lyme, Connecticut in 1975. It can start with a characteristic “bull’s eye” rash, in which there is a central spot that is surrounded by clear skin that is then ringed by an expanding rash. It can also appear just as an expanding rash.

This rash usually starts within days of the tick bite. Eye problems can occur along with this rash in the first phase of the disease. This includes red eyes that can look like full-blown pink eye, along with eyelid swelling. It also can produce iritis or uveitis, which include sensitivity to light and inflammation inside the eye.

The second phase of the disease usually starts within a few weeks of the tick bite and this occurs because the spirochete gets into the blood stream. This stage often has rashes starting away from the original bite site. It can also produce joint pain, weakness, and inflammation in several organs including the heart, spleen, liver and kidneys.  

There are also several ways it can affect your eyes. It can cause inflammation in your cornea (keratitis), retina (retinitis), optic nerve (optic neuritis), uveitis, inflammation in the jelly-like substance that fills the back of the eye called vitreous (vitritis) and the muscles that move your eye around (orbital myositis). It can also affect the eye if it causes problems with the nerve that controls your eyelid muscles so that your eye will not close properly (Bell’s palsy).

There is a third phase of the disease that is caused by long-term persistent infection.  This phase can create multiple neurologic problems and can appear very similar to the presentation of Multiple Sclerosis (MS). The eyes can show any of the same signs as phase two, but the most common presentation is persistent keratitis.

The diagnosis is made by observing the presenting symptoms, being in an area where there are significant numbers of the disease-carrying ticks, and a blood test that can confirm the diagnosis.  

The symptoms and signs of Lyme Disease can mimic many other problems, so it is important to keep Lyme Disease in mind if you are having multiple problems involving different organs and you know or have any suspicion that you may have had a tick bite while you were in areas where the disease is prevalent.
