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?

Red, Itchy, swollen eyelids are often due to a condition called blepharitis. Blepharitis tends to be a chronic condition due to thick eyelid mucous gland production that sticks to the bases of the eyelashes. This adherent mucous can allow bacteria to overgrow and also attract and retain allergens. The standard treatment for blepharitis is doing warm compresses and cleaning off the eyelids with a mild baby shampoo and water solution.

This treatment works for some people but there are many more sufferers who have chronic irritation and relapses despite this treatment. If the warm compresses and eyelid scrubs are not quite keeping the condition under control there are several other additional treatments that can be used to control the symptoms.

One such treatment that your doctor may decide to use an antibiotic/steroid combination drop or ointment. We usually use these for short periods of time to try to bring the condition under control. They are not good to use chronically because it can build resistant bacteria and the steroid component can cause other eye issues like cataracts and glaucoma. The treatment is very safe for short term use but chronic use is usually not a good option.

There are also antibiotic eyelid scrubs such as Avenova which can be prescribed and used on a more chronic basis.

Oral Doxycycline can also be used more chronically in very low doses. Doxycycline is an antibiotic that when used to treat infections is generally prescribed in a dose of 100mg twice a day. For chronic Blepharitis suffers we generally use a much lower dose of around 50 mg a day. At that dose we are using the Doxycycline to help thin out the mucous production from the eyelid glands more than for it’s antibiotic properties.

In summary, Blepharitis can be a chronic issue that requires some persistent “maintenance” work be done to keep it under control with further intervention sometimes needed for flare-ups.
