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.

Obesity is now hitting critical levels, and affecting every branch of medicine. The Center of Disease control (CDC) now reports obesity affects 4 out of 10 people. Furthermore, 3 out of 10 people are considered overweight, just shy of obese. The effect on eyes is greatest on the small blood vessels of the eye, which can cause bleeding which leads to blindness. This is mostly in association with systemic diabetes or hypertension in which obesity is a leading factor. Obesity has a very real and lasting effect on individuals and families.

Certain health effects that come as result of obesity are as follows:

Cancer: In some cases, excess fat cells can affect the growth of tumors, according tho the NCI (National Cancer Institute), and thousands of cancer cases are linked directly to obesity.

High blood pressure: Aneurism,stroke, heart failure, and death are the consequences of hypertension. According to the American Heart Institute, obesity is a leading cause of heart disease. Blood pressure is simply the force of the blood pushing against the arteries, and too much pressure weakens those vessels over time. Obesity causes these vessels to strain more than normal.

Diabetes (type 2): Being obese puts extra work and stress on the body’s natural ability to maintain proper glucose levels for the bloodstream, which in turn creates a greater need for insulin. Over time, the body cannot make enough insulin to keep up, thus creating a diabetic state. Over 80% of people with type 2 diabetes are overweight, so decreasing obesity can markedly lower your chance of developing type 2 diabetes.

Infertility and premature birth: Overweight women have greater risk in delivery, because too much fat can weaken the cervical membranes. Additionally,overweight women have more trouble getting pregnant because of the effect of obesity on hormonal changes that impact conception.

Insomnia: According to the American Sleep Foundation, obesity is linked to sleep apnea, preventing a restful night sleep. Interruption in sleep patterns due to momentary gasping for breath can have a poor overall effect on all health aspects of life.

Losing weight through daily diet, exercise, and the help of your physician and dietician are viable solutions and treatment for obesity. Eliminating obesity can attribute to a healthier lifestyle and in many cases can extend or save your vision and your life.
