Always the Little Things: Bad Habits That Can Damage Your Eyes

Always the Little Things: Bad Habits That Can Damage Your Eyes

Everyone’s got their funny little habits. They range from quirky to cute to well, sort of gross (nail biters unite), but they’re all generally pretty harmless. However, as we always seem to say, even the little things can have big impacts on your sensitive, sensitive peepers.

Follow along, and we’ll delve into a couple of the everyday habits many of us have developed that aren’t so easy on the eyes. With any luck you’ll be able to whip through this article and leave armed with some basic eye-protecting knowledge. No one ever drops a habit overnight, but if you catch yourself consistently doing anything on this list, then it’s probably time to start thinking about making some changes.

Always the Little Things: Bad Habits That Can Damage Your EyesEye Rubbing

We all do it. Eye rubbing is a perfectly natural behavior, and generally not an awful one. Rubbing encourages the eye to produce tears, making it a natural response to dry, itchy eyes caused by allergies or sleeplessness. Not only that, but it also presses down on a specialized piece of equipment called the sensory trigeminal nerve, which in turn communicates with the vagus nerve, and that’s where things get interesting.

Stimulating the vagus nerve actually helps reduce heart rate and blood pressure – a phenomenon called the oculocardiac reflex. The changes induced by this reflex can help a person relax during tense situations, and effects can be pretty dramatic. Ever seen someone step away from a heated argument to rub their fists in their eyes? They’re unconsciously taking advantage of the oculocardiac reflex. Rubbing also helps relax the muscles around the eyes, which can be strained by long periods of visual concentration.

So, wait… all that sounds pretty great. What’s wrong with eye-rubbing? If done in moderation, the answer is probably “not much”, but it changes quickly the more you rub. Excessive rubbing can rupture blood vessels in and around your eyelid, giving you the “caffeinated panda” look sported by students and other late-night workers. Your hands are also less-than-cleanly, and rubbing too much puts you at greater risk of transferring germs from your hands to your eyes.

Finally, and perhaps most worryingly, rubbing can physically damage the cornea, thinning it out and causing it to distend forward, resulting in a condition known as keratoconus, which can require surgery to treat.

If you’re becoming increasingly worried about your own eye-rubbing after reading all that, there are a few ways to trim the habit back. An awful lot of rubbing comes as a response to dry or strained eyes, and guess what we all do that dries out and strains our eyes? Hate to say it, but you’re doing it now.

Staring at a laptop or tablet screen for too long results in what some physicians call “computer vision syndrome.” The combination of a an unblinking gaze and the close proximity of most screens to your face gives you those scratchy, tired eyes, and encourage more rubbing.

Fortunately, there are some things to do to combat it. First, sit a bit further way from your computer screen, many manuals recommend arm’s length or more. Second, try to take breaks. Grab a few seconds every so often to stand up, walk around, and focus on something other than the screen.

Catching a Bit Too Much Light

“Don’t stare at the sun” is parental advice as old as “don’t go swimming after eating.” And, believe it or not, they’re both fairly sound advice. We won’t go into the precise mechanisms of munching and swimming, but we do need to talk turkey about your eyes and UVB damage. An awful lot of the study into the exact effects of ultraviolet radiation came about several years ago amidst panic about a depleting ozone. The ozone hasn’t exactly stopped depleting, so all findings from then seem to be doubly applicable moving forward.

By far the most common sun-related injury to the eyes is photokeratitis, a condition similar to sunburn that affects the eyes. Symptoms include the usual sunburn suspects: discomfort, redness, tearing and, most poetically “a sensation similar to having sand in the eyes.” Lovely.

However, it’s not the only thing that can happen after an overzealous day at the beach, and it’s actually far from the worst. UV radiation has a well-documented tie to cancer. Those harmful rays can easily damage tissue if you overexpose yourself to them. And while you’ve probably heard about the importance of sunscreen a million times or more, it’s important to remember that your eyes are equally at risk. Carcinomas and melanomas can both develop if you let your eyes cook for too long – and believe it or not, your orbs won’t even get much of a tan.

A host of other chronic conditions, notably cataracts, can also be exacerbated by too much time in the sun. Pingueculas, pterygium, and similar problems are among the nastiest-looking things that can happen. They’re small, but very visible deposits that form on and around the eyes as a response to UVB damage – if you didn’t wear sunglasses before getting them, you’ll likely want to start afterward.

Thankfully, there’s a pretty easy solution here: wear your shades. Specifically your polarized sunglasses, which help filter out harmful forms of radiation. Even cloudless days can have plenty of light filtering down through the gloom, so if you’re planning to be outside for a long period of time, haul along your favorite pair of sun blockers.

Everyday Maintenance

At the end of the day, try as we might to prevent it, our eyes will still take some hits. Short of wearing one of those doggy elizabethan collars, we can’t really keep from rubbing our eyes every so often – reflexes are reflexes after all. And the sun? Sort of hard to avoid as we can’t really sanction never going outdoors.

Still, you’ll be doing yourself and your eyes a favor if you follow the above advice, and that’s just the tip of the iceberg. Instituting a regular regimen of proper nutrition specifically tailored for your eyes can help make up the environmental risks they normally face. Our Ocu-Plus Formula might not be able to block out UV radiation (though a sweet pair of aviators might), but it can help ensure your eyes are in the best shape they possibly can be all day, everyday.

    Always helpful information given here. For night riding on my bike, I purchased
    work related goggles to protect my eyes from bugs, dust, rain,cold wind and sometimes even blowing snow.
    All the tips have helped me to keep my vision at 20/20. I passed my driving medical test with flying colour,s only last month.
    Thank you Rebuild your Vision.

    Among our various organs, the eyes are our most valuable asset.
    Thanks for helping preserve our vision. At 80, in my last exams,
    I was informed of a loss of optic nerve fibers in both eyes. The
    opthalmologist impressed the importance of keeping the eyes well
    moistured by applying recommended eyedrops several times 3-4
    during the day.

    During my last eye exam (~2 years ago) the opthamologist said, “this will be your last prescription change, you will need cataract surgery next.” I am 69 & have been wearing corrective lenses since I was about 12; UNFORTUNATELY. The usual victim, Billy can’t seem to read the blackboard when actually Billy was uninterested in paying attention and had un-matured eyes. I do not have “obscured vision” rather out of focus. The Dr. explained the condition was a matter of change in the refractive index in the light’s pathway. This makes sense since I can press my current glasses closer and experience sharper vision. I am EXTREMELY RELUCTANT to get “cataract surgery.” What nutritional means or OTC holistic eye drops, or Billbarry or ??? would be effective? And, as a last resort how about careful use of contact lenses used with glasses added for close vision? Quite some time ago I tried soft contacts, weighted to include astigmatism correction with poor results, including the fact that my normal tear production had long since largely became dormant. Thank you for your ideas and time.
