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?

A common in-office procedure is an eye injection for treatment of various eye conditions, such as wet macular degeneration, diabetic retinopathy or vein occlusion.  

It is normal to be anxious prior to your first eye injection but knowing what to expect may alleviate some anxiety.  

Your eye will be numbed with topical anesthetic drops. Usually, a cotton-tipped applicator soaked in anesthetic will be held against the white part of the eye to numb it.  Sometimes, a thick gel may also be used for numbing. Once the eye is numbed, it will then be cleaned and a small instrument will be used to hold the eye open. During the actual injection, some patients feel pressure while others may feel a quick sting. Each person will have a different experience and each injection will be different.

The medicine is injected into the white part of the eye. Sometimes a blood vessel may be encountered during the injection and you may notice a little redness on the outside of the eye. This is purely a cosmetic symptom and the redness will disappear within the next couple of days. Patients may also experience some mild irritation after the injection due to the drops that are placed in the eye. I usually recommend over-the-counter artificial tears drops to use after the injections. Usually, the eye should feel normal by the next day.  

Another common symptom after an injection are floaters. These floaters usually appear as small bubbles in the lower half of your vision, but they will disappear in in a day or two.  

There are no activity restrictions after the injection and no antibiotic drops are needed.  

Things to watch for after the injection:

- If your eye gets painful or redness develops a couple of days after the injection, then you should call to be seen.  

- If your vision declines or you notice increased or hundreds of floaters then you should call to be seen.

Otherwise, patients are usually initially seen once a month after they first start injections
