How do Contact Lenses Work?

A contact lens is nothing more than a tool crafted to adjust the optics of your existing biological lens, the human eye. When you suffer from blurred or impaired vision, it is simply due to the fact that your eyes aren’t able to focus the light coming in directly onto your retinas.

Your retina is the layer of membrane at the back of the eyeball; its center dimple, called the fovea centralis, is the sharpest point of vision, as well as where the majority of color is perceived.

Contact lenses are applied to the cornea of the eye, where they operate in largely the same capacity as eyeglasses do – by helping your eye focus the light coming in directly through to the focal part of your retina.

For those with myopia, or nearsightedness, the inability to see farther away is the result of an elongated eyeball, wherein the light that is focused in the eye lands in front of the retina, rather than on it. This is corrected by minus lenses, whose concave shape is thinner at the edges than at the center so to spread the light away from the eye’s lens, adjusting the focal point of the light forward.

Conversely, an eye that is too short is cause for hyperopia, or farsightedness. This contact lens will bend the light toward the center and move the focal point back through its convex design, which is thicker at the center. In this way, the light is focused on the retina, rather than behind it.

Depending on how much the light bends, your vision will require contacts or bifocals of different strengths, which are expressed in diopters: The higher the diopter, the stronger the lens. As for the choice between hard and soft contacts and glasses, that is a matter of personal preference.

Most importantly, contact lenses bring the wearer as close as possible to corrected natural sight, since they move with your eyeball, allowing for a more natural field of vision. Contacts do not get in the way of your line of sight, and brands like Biofinity and Acuvue can be worn daily for weeks or even a month before they need replacing.

Applied to the cornea of the eye, contact lenses are able to stay in place by a combination of pressure from the eyelid and adhesion to the layer of tear fluid which floats on the eye’s surface. Each time you blink, your eye will secrete lubrication to the cornea which flushes out bacteria and impurities that may get stuck to the lens. These days, soft contact lenses are more popular as they can be worn longer without causing the same rough irritation as hard lenses. Made of soft, gel-like plastic, the material is designed to absorb water and allow oxygen flow for the sake of both comfort and hygiene.

Other irregularities that can be improved with the use of contact lenses include astigmatism (the curvature of the eye’s lens or an oddly shaped cornea), and presbyopia (the natural aging of the lens). Talk to your eye doctor about what steps you can take to improve your sight today.

 

Famous Cartoon Characters Without Their Glasses

Whenever a cartoonist gives a character glasses, he/she seems to make the spectacles a focal point of the character’s appearance. As we at RMC are always the curious bunch, we decided to search out pictures of notable cartoon characters without their glasses to see what they would look like if they were loyal Replace My Contacts customers and were not chracterized by their frames.

Daria

Daria’s “manstopper glasses” were easily the most recognizable aspect of our favorite grunge-inspired 90’s hipster (before hipsters existed).

Chuckie Finster (of Rugrats)

Chuckie

Millions of children grew up going on adventures with Tommy, Chuckie, and the rest of the gang. Unfortunately, it seemed that Chuckie lost his glasses (and Rugrat friends) more often than not. Though, as a toddler, he was a wee bit too young for contacts, most children can benefit from lenses as young as eight-years-old.

Dilbert

DilbertIt’s hard to tell if our Sunday mornings would be the same if Dilbert was sporting Acuvue contacts instead of his iconic circle glasses. That being said, he certainly seems more Milhousewide awake and ready to face the day!

Milhouse Van Houten (of The Simpsons)

The self-proclaimed king of cool, Milhouse Van Houtten could never seem to get lucky with his love, Lisa Simpson. His iconic coke bottle glasses never seemed to helped his case either. Not unlike Steve Urkel, we feel that this iconic character is better off without the frames.

Velma Dinkley (of Scooby Doo)Velma

Prone to losing her glasses, Velma always seemed to need contacts in the worst way. Whether it was being chased by ghosts or monsters, she could have really benefited from picking up a pair of Avaira contacts.

Did You Know These Athletes Wear Glasses or Contacts?

Athletes – we think of them as super heroes that are capable of unparalleled acts of strength, perseverance, agility and speed. Their forms and physical aptitudes are placed on pedestals and envied by thousands. However, one detail that we tend to overlook is that many sports heroes rely upon contact lenses when engaging in their chosen profession. Yes, these women and men may seem bodily flawless, but the perfection does not extend to their eyes. These following athletes often sport glasses in their ordinary lives, reminding us that anyone can use an ocular boost now and then.

There are many reasons for a person to wear glasses including fashion, necessity, and protection.  Athletes are no different.  From all walks of life, these superstars decide to look great and see their life through the eyes of a perfect pair of specs.  Here are a few athletes that you might not have known wear glasses.

There are many reasons for a person to wear glasses including fashion, necessity, and protection.  Athletes are no different.  From all walks of life, these superstars decide to look great and see their life through the eyes of a perfect pair of specs.  Here are a few athletes that you might not have known wear glasses.

LeBron James is the perfect example of an athlete that steals the camera lens on and off the court. Aside from his excellent 3 point shots and amazing court game, loyal fans know him for his off the court antics and fashionable choices head to toe. Increasingly becoming an iconic staple for the basketball player is his “hipster” black framed glasses. However, these are for aesthetic purposes, as he underwent LASIK surgery years ago to correct astigmatism and myopia.

Washington National’s Baseball player Bryce Harper caught the media’s attention by sporting red contact lenses during a game. Yes, it might have come across as somewhat intimidating, but the real motivation behind his action was to lessen the glare of the sun. This tactic is not unheard of among athletes, but there is a lack of sufficient evidence to universally support this effort. However, many Acuvue contact lenses like Oasys for Astigmatism and Advance Plus provide UV protection in order to shield this sensitive part of the body from the sun’s rays.

AndersonWith 20 plus knockouts, Anderson Silva is an all-around UFC super champion.However, you might have never guessed this if you stood next to this gentleman on the bus; while he isn’t exactly built like Arnold Schwarzenegger, the real reason this elite athlete blends in so well is undoubtedly due to his glasses. Upon stepping in the ring though, when his death glare is undiluted by his frames, no one doubts that Silva is not a man to be messed with.

Lastly, even footballers like Von Miller benefit from contact lenses. Though this Broncos player is often photographed sporting stylish glasses, he always ditches the delicate frames for contacts when it comes to hitting the field. He’s so passionate about corrective vision that he started Von’s Vision, a nonprofit that provides contact lenses and glasses to youths.

Coffee and Eye Health: Dry Eyes and Glaucoma

3311551526_9fb4e662a0_bCoffee is often seen as the end-all-be-all solution to fatigue and lack of focus. 54% of Americans over the age of 18 drink this beverage on a daily basis, and the average number of cups that someone in the US consumes day-to-day is 3.1.

Coffee is naturally produced from cocoa beans, but what people commonly drink is synthetically produced with the purpose of being used for in many of our medications and beverages. Besides stimulation, it is being produced for the satisfaction it provides with many flavors. It’s something that we as a culture have come to expect as a necessity in our days. What is commonly forgotten is that coffee wasn’t intended to be used for long durations.

The Side Effects of Coffee:

You know the old saying: “too much of a good thing is a bad thing.” In the case of coffee this phrase is accurate.

Constantly drinking our beloved beverage can have noticeable damage to our health. When consuming the beverage, your body can experience various changes in blood sugar levels. The results of this happening can include blurred vision and waving flashing lights. With changes in your vision you can additionally experience migraines and lingering pains near your eyes. The damage that occurs to your vision will be temporary in most cases, but as they occur it will be uncomfortable.

Researchers have found that those people who drink three cups or more of coffee a day put them at risk for exfoliation glaucoma, which is the leading cause for blindness.

2295096211_1c641c008eBesides your eyes high blood sugar can cause you to experience flushed skin, nausea, stomachaches, constant urination, loss of appetite, and issues with breathing. Low blood sugar causes major increases in hunger, rapid increases to heart rate, shaking, and confusion.

It is widely stated that people should not consume more than 1 to 2 cups of coffee, 3 is pushing it, and 4 will lead to increased health risks over time. These increased risks are seizures, convulsions, and as mentioned above, exfoliation glaucoma.

Does it help with Dry Eyes:

Coffee isn’t without its merits as well. On top of the elevated energy, studies are now saying that caffeine could also boost tear creation for those with dry eyes. This common and irritating condition can lead to a burning feeling, redness and the feeling of eye fatigue. If you’re suffering from such a condition, incorporate a cup of joe into your morning routine and consider switching your prescription to a lens that inherently stays lubricated, like Acuvue TruEye or Avaira contacts. 

Going Forward:

No, you don’t have to stop drinking coffee. Try limiting the amount of coffee that you ingest everyday. Your body will grow to adjust to the new volume that it is taking in and will be able to run off of that. You can also try substituting decaf in place of one or two of your typical drinks. Another thing that helps wake you up may be a surprise to some, exercise. If the endorphin release is timed well before work, they could get you through much of your day without the assistance of coffee.

Regardless of what approach you choose to take, protecting your eyes and your body should be important to you; make the extra effort and pull the reins back.

Causes of Dry Eyes

SONY DSCThe distracting discomfort that accompanies dry eyes is enough to ruin almost any happy day – it brings about unnatural feelings of fatigue, inability to focus when reading, redness and sometimes physical pain. Many of us reach for the bottle of eye drops to remedy this symptom, and give little thought to what could be causing this irritation. To consider what may be the culprit for your own dryness, check out the popular causes below!

1)      Age. Our skin isn’t the only thing to lose moisture with the passage of time; it’s fairly common for people in their twilight years to naturally produce less tears. This is especially true for females who are postmenopausal.  Furthermore, diseases that are commonly associated with old age are also tied with dryness, like rheumatoid arthritis, shingles and lupus.

2)      Exterior influences. There is plenty in our environment to cause dryness, like wind, smoke and dust. However, there are plenty of physical conditions that can lead to irritation as well. For example, it isn’t uncommon that people with blepharitis, eczema and dandruff have particles of dry skin fall into their eyes. It’s important that your contacts are clean of all such debris; make sure you diligently clean your lenses or consider purchasing daily options like Focus Dailies and Acuvue 1 Day Moist that can be replaced after a single use.

3)     OLYMPUS DIGITAL CAMERA Working with computers. How many times did you blink while you were reading this blog post? Chances are, not enough.  In addition to making a conscious effort to blink more, consider looking away from the screen every 15 minutes to let your eyes rest, darkening the screen’s luminosity, and sitting 1.5 – 2 feet –way from the device.

4)      Sun exposure. Similar to the above note, being exposed to UV rays for a long period of time can have a damaging, drying effect on your eyes. While the dryness should be temporary (if you give your peepers a chance to rest), it can also lead to serious outcomes like cataracts, macular degeneration and more. Therefore, consider wearing sunglasses outside between the hours of 10 AM and 4 PM, even if it is not summer. Furthermore, consider lenses that incorporate UV protection, like all of Acuvue’s contacts.

5)      Fluctuating hormones. Women commonly develop this annoying condition at points in their life in which their bodies are undergoing changes. Whether you’re pregnant, taking estrogen supplements during menopause or are dealing with a inconsistent thyroid, the physical readjustment can all spur feelings of dryness.

6)     Avocado_Whole_and_Crossection Not receiving enough Vitamin A and Omega 3 Fats. This nutrient shelters the cornea against bacteria. While there are eye drops infused with Vitamin A, you can also incorporate items like sweet potatoes, cantaloupe, tuna and mango into your diet. Omega 3 fats have been credited with improving everything from our circulation to our complexions, and our eyes are no exception. Found in foods like tofu, chia seeds, salmon and avocados, it assists with the creation of tears.

7)       LASIK. While the idea of not having to daily sport heavy frames is certainly appealing, eye surgery can diminish your eye’s ability to generate moisture. Luckily, this effect is often temporary, lasting upwards to six months.

8)      Certain Medications. A wide range of medications have been credited with spurring the dryness of eyes, from acne aids and decongestants to birth control and antidepressants. It’s important to learn about the potential side effects of anything you put in your body, so make sure to ask your doctor whether whatever medications or supplements you take could be causing the unnatural dryness.
