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? Here at Infinity Eye Care, we can customize any style of frame and lens prescription with blue light-blocking technology.

Eye exams, education are important when it comes to knowing about cataracts

Cataracts affect millions of Americans and are a common cause of vision loss as we age.

That’s why it’s important to be aware of cataract symptoms and to have regular eye exams to help diagnose problems and monitor your vision.

Cataracts affect your eyes by causing cloudiness or opacity to the normally clear lenses that focus light to the retina at the back of your eyes. A cataract distorts that light, which can cause blurry vision and make your eyes sensitive to bright lights – especially at night.

The water and protein that make up the lens or each eye can change as you age, with the protein clumping together to cloud the lens. As the cataract grows it becomes harder to see clearly and may require surgery to remove and replace the lens.

Causes of cataracts:

  • Aging is the most common cause.
  • Diseases such as diabetes or hypertension.
  • Exposure to ultraviolet light from the sun.
  • Smoking and excessive alcohol use.
  • Injury to your eyes.
  • Use of steroid medications
  • Family history.

Symptoms of cataracts include:

  • Blurry or cloudy vision.
  • Problems with night vision.
  • Glare from the sun, headlights or other light sources.
  • Colors may start to seem faded.
  • Double vision.

Diagnosis of cataracts:

While it is important to have regular eye exams, you should contact your eye care professional if you notice cataract symptoms. Testing can include:

  • Visual acuity testing to determine how well you see at different distances.
  • Visual field testing to check your peripheral vision.
  • Questions about your vision and medical history.
  • Examination of the lenses of your eyes to check for things that indicate a cataract.

Treatment of cataracts:

  • The necessity of cataract surgery and the surgery itself is something that should be discussed by you and your eye doctor.
  • Cataract surgery is very common and usually is performed without complication on an outpatient basis.
  • The lens with the cataract is removed and often replaced with an intraocular lens (IOL), which is implanted in the eye about where your original lens was.
  • Your doctor will discuss the recovery period after your surgery with you.
  • While the IOL may correct your distance vision, it’s likely you will need reading glasses.

If an IOL can’t be used, your doctor will discuss options with you.

Things you can do to protect your eyes:

There is no scientific proof that you can prevent cataracts, but here are some things experts say can reduce your risk:

  • Get regular eye exams. Early detection of eye problems might save your sight.
  • Wear polarized sunglasses to protect your eyes from harmful UV rays.
  • Quit smoking and limit alcohol consumption.
  • Eat healthy, including fruits, vegetables, nuts and fish high in omega-3 fatty acids. These foods provide vitamin C, vitamin E, as wells as lutein and zeaxanthin. Be sure to discuss any diet change with your eye care professional.
  • Keep diabetes under control.

It’s important to know how cataracts can affect your vision and even more vital to have regular eye exams to screen for cataracts and other problems that can affect your sight as you age.
