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.

You’ve been diagnosed with a cataract and you’ve been told you should have cataract surgery. The surgeon is also telling you that you should consider paying extra out of pocket it for it.

Where did this come from? Why should you have to pay out of pocket for cataract surgery? Shouldn’t your health insurance just cover it?

In trying to answer those questions, you will first need a little history of both cataract and refractive (correcting errors of refraction such as nearsightedness, farsightedness and astigmatism) surgery.

Radial keratotomy (RK) was the first widely used refractive surgery for nearsightedness. It was invented in 1974 by Russian ophthalmologist Svyatoslav Fyodorov, and it was the primary refractive procedure done until the mid-1990s. Then it was surpassed by the laser procedure called PRK and then, eventually, LASIK; they are still the predominately pure refractive surgeries done today.

Cataract surgery has its origins all the way back to at least 800 BC in a procedure called couching. In this procedure, the cataract was pushed into the back of the eye with a sharp instrument so the person could look around the cataract. Medically that is all that was done with cataracts until around 1784 when a cataract was actually removed from the eye.

The next big advance was implants to replace the removed cataract. The invention of implants was spurred by Harold Ridley, who recognized that injured Royal Air Force pilots could retain shards of their canopy made out of a substance called PMMA in their eye without the body rejecting it. Implants became commonplace after the FDA approved them in 1981. The implants have improved over the years and most implants today are foldable so they fit through a tiny incision of around 3 millimeters.

Medicare and most other insurances cover the cost of MEDICALLY NECESSARY cataract surgery. This means they will cover the surgery when someone has symptoms of visual trouble that is interfering with their normal daily activities AND the cataract is the cause of those visual disturbances. There is no reason to remove a cataract just because it is there. It needs to be causing a problem to make it medically necessary to remove it.

Medicare and most other insurance do not cover refractive surgery (Lasik, PRK, etc.). The general perception of refractive surgery by the insurance industry is that it is not MEDICALLY NECESSARY. You can correct the refractive errors in almost all cases by means other than surgery, such as glasses and or contact lenses.

Today there are methods of doing additional procedures, or using special implants, at the time of cataract surgery to correct more than just the cataract alone. This is where the two types of surgeries, refractive and cataract, have merged into a single operation that tries to take care of both problems.

The merging of cataract and refractive surgeries is why there are now options not only to get your cataract removed but also to have your astigmatism (irregular shape to cornea) and presbyopia (the inability to see well up close that hits nearly everyone in their 40’s) corrected.

This is where the "paying for cataract surgery" comes in. Surgery to correct astigmatism and presbyopia are not considered MEDICALLY NECESSARY because they can be corrected with eyeglasses or contacts.

Your cataract, once it hits a certain point, cannot be corrected with glasses or contacts and therefore it is MEDICALLY NECESSARY and your insurance will pay for that component of your surgery. What it won’t pay for is any additional amount that is charged to correct your astigmatism or presbyopia.

If you want to address your astigmatism and or presbyopia at the time of cataract surgery to be less dependent on wearing glasses after surgery then paying for those components is going to be an out-of-pocket payment for you.
