Myths/Facts

Sunglasses

To help make the experience of buying a pair of sunglasses a little less confusing, here's the truth about some of the most common myths about sunglasses:

Myth #1: Sunglasses with 100% UV protection are expensive
False: You do not have to pay a premium for proper UV protection. While more expensive sunglasses may offer more stylish frames, higher quality lenses, sharper images and less glare, it is very easy to find inexpensive glasses that offer 100% UV protection. Mi OPTICA purchased several pairs of glasses for $19.99 and up at a sporting goods store. When tested, they lived up to their claim of 100% UV protection.

Even two pairs of $10 glasses from a local souvenirs shop also made good on their 100% UV protection claim. However, one of the $10 pair of sunglasses had a “100%” sticker on the lens and turned out to not offer the advertised level of protection. So if you do buy an inexpensive pair of glasses, you might want to have them tested by an optometrist.

Myth #2: Lenses with darker tints are more protective than lenses with a lighter tint
False: The tint of the lens has nothing to do with the UV protection of the glasses. A clear lens with no tint and 100% UV protection is better for your eyes than dark, heavily tinted sunglasses without UV protection. In fact, dark lenses without adequate UV protection are actually worse for your eyes than not wearing glasses at all, because the dark tint causes your pupils to become dilated, thus exposing your eyes to more harmful UV light.

Myth #3: You should have UV coating put on your lenses for extra protection
False: If your glasses already have UV protection, they do not need to have added protection put on them.

Myth #4: Photochromic lenses don't block out UV rays as well as regular sunglasses
False: As long as they offer 100% UV protection, photochromic (such as Transitions-brand lenses) lenses provide the same level of UV protection as regular sunglasses.

Myth #5: Polarized, anti-glare lenses are all you need to protect your eyes from UV rays
False: While polarized and anti-glare lenses may offer better image clarity, a more comfortable viewing experience and give you better vision when driving or playing sports, they have nothing to do with UV protection. That being said, most polarized lenses also offer adequate UV protection. Again, if you are in doubt, have your sunglasses checked by an optometrist.

Myth #6: Lens color is important when it comes to blocking UV rays
False: Just like lens tint, lens color has nothing to do with protecting your eyes from UV rays.

Myth #7: Yellow- or amber-tinted “Blue Blocker” lenses offer more protection than regular sunglasses
False: While some experts argue that the so-called “Blue Blocker” lenses block additional light waves that are harmful, only some research has proven this for certain, and “Blue Blockers” are currently viewed by most experts as a personal preference choice. Most patient had experienced these Blue blockers lenses as smooding effect on the eyes.

Myth #8: Children don't need sunglasses as much as adults
False: Children often spend even more time in the sun than adults, and need proper UV protection just as much. It is also far more common to find cheap children's sunglasses that do not provide adequate UV protection. Always have your children's sunglasses tested for proper UV protection.

Myth #9: You don't need sunglasses on a cloudy day
False: UV rays are just as potent on a cloudy day as they are on a clear day, and proper eye and skin protection is always needed.

Vision

I’m sure you have heard the vision myths while you were growing up. Your mom telling you “you’ll hurt your eyes if you sit too close to the tv” or my favorite “eat your carrots for better vision”. Well, I think it’s time to get to the bottom of all these vision myths and get some vision facts once and for all! Just because something is a common belief doesn’t make it true. A lot of things you have probably heard about your vision turn out to be false. Here are some common myths that have no basis in science.

Myth: Sitting too close to the TV will ruin your eyes

Fact: Your mom may have warned you that you would ruin your eyes forever if you sat too close to the television or if you watched too much of it. Unfortunately for mom, that's not true. Watching televisions, including LCDs and flat screens, can't cause your eyes any physical harm. The same is true for using the computer too much or watching 3-D movies. Your eyes may feel more tired if you sit too close to the TV or spend a lot of time working at the computer or watching 3-D movies, but you can fix that by giving your eyes a rest. The truth is if you need to sit close to the tv to clearly see what is going on, you may already have vision problems.

Myth: Wearing glasses makes your eyes dependent on them

Fact: Eyeglasses correct blurry vision. You may want to wear your glasses more often so that you can see clearly, but your glasses aren't changing your eyes so that they become dependent on your eyeglasses. You're just getting used to seeing things more clearly. Similarly, wearing glasses with the wrong prescription won't ruin your eyes. You just won't see as clearly as you would with the proper prescription.

Myth: Only boys are color blind

Fact: Color blindness, also known as color deficiency, occurs when you are unable to see colors in a certain way. Most commonly, color blindness happens when a person cannot distinguish between certain colors, usually between greens and reds, and occasionally blues. While males are much more likely to develop color blindness, females can also have the problem.

Myth: Eating carrots will make your eyesight sharper

Fact: Carrots are a good food for healthy eyesight because they contain vitamin A, a nutrient important to your eyes. However, a balanced diet can contain lots of foods that offer similar benefits. In any case, eating a lot of carrots won't help you see better unless you suffer from vitamin A deficiency, which is rare in Curacao. Also, eating too many carrots can be its own problem, causing your skin to turn yellow.


Myth: Using the eyes too much and "wear them out

Fact: We wouldn't lose our sense of smell by using our nose too much or our hearing by using our ears too much. The eyes were made for seeing. We won't lose our vision by using our eyes for their intended purpose. 

Myth: Wearing eyeglasses that are too strong or have the wrong prescription will damage the eyes 

Fact: Eyeglasses change the light rays that the eye receives. They do not change any part of the eye itself. Wearing glasses that are too strong or otherwise wrong for the eyes cannot harm an adult's, although it might result in a temporary headache. At worse, the glasses will fail to correct vision and make the wearer uncomfortable because of blurriness, but no damage to any part of the eye will result. 

Myth: Wearing eyeglasses will weaken the eyes

Fact: The eyeglasses worn to correct nearsightedness, farsightedness, astigmatism, or presbyopia will not weaken the eyes any more than they will permanently "cure" these kinds of vision problems. Glasses are simply external optical aids that provide vision to people with blurred vision caused by refractive errors. Exceptions are the kinds of glasses given to children with crossed eyes (strabismus) or lazy eye (amblyopia). These glasses are used temporarily to help straighten the eyes or improve vision. Not wearing such glasses may lead to permanently defective vision. 

Myth: Having 20/20 vision means that the eyes are perfect

Fact: The term "20/20" denotes a person with excellent central vision. But other types of vision-such as side vision, night vision, or color vision might be imperfect. Some potentially blinding eye disease, such as glaucoma or diabetic retinopathy, can take years to develop. During this time, they are harming parts of the inner eye, but the central vision can remain unaffected.

 

Myth: Reading in the dark can damage your eyes

Fact: We have all read in the dark once or twice in our lives I’m sure. Lucky for us, the only thing this will cause is eye fatigue. You may get a slight headache and your eyes will become tired a bit quicker causing words to seem blurry but this is only temporary and no permanent damage has been done to your vision.

Myth: Wearing someone’s glasses will hurt your eyes more then it will help
Fact: There is a slight truth to this one. While you are wearing someone else’s glasses your eyes will not be working as they normally would. This however is only temporary and as soon as you take the glasses off your eyes will automatically adjust back to normal.

Myth: Vision loss happens and there is nothing you can do to prevent it
Fact: There is some truth to this, while as we age our vision will naturally deteriorate and won’t be as sharp. But, you can slow this down with a healthy diet, wearing protective eye gear such as goggles or sunglasses, and having regular eye exams.

Myth: Starring at the computer all day will ruin your eyes
Fact: When you stare at anything for an extended period of time you tend to blink less causing dryness and eye strain but will not affect your vision. It is recommended for you to take regular breaks and frequently glance away from the computer when working for an extended amount of time. Now a days there computer glasses that will take help your eye get less fatigue.

Myth: Staring directly at the sun is okay if you squint or are wearing sunglasses
Fact: It is never recommended to stare at the sun. The sun produces ultra-violet rays which can cause damage to your cornea, lens, and retina. Even the best sunglasses can’t block UV rays 100%. It should also be noted that staring directly at a solar eclipse can cause blindness.

Myth: Crossing your eyes will make them stay like that
Fact: When you cross your eyes for humor or amusement it may cause a few laughs but it will not cause permanent damage to your eyes and once you are done your eyes will return to normal placement. Our eyes naturally come together when we look at something closely so when you purposefully cross your eyes you are just exaggerating your eyes natural response.

Myth: Children with crossed-eyes or misaligned eyes will grow out of it as they get older
Fact: Crossed-eyes, a condition called strabismus, and misaligned eyes, a condition calls amblyopia, will not correct themselves over time. The eye must be forced to correct this by using patching, glasses, eye drops, or surgical procedures. The best results are achieved when the corrections are started as soon as possible and even before the age of 6.

Myth: You don’t have to have regular eye exams and only need to have your eyes checks when you are experiencing problems
Fact: It is very important and highly recommended to have regular eye exams. Regular eye exams can prevent eye disease, help find other health problems, and correct eye problems at an early stage helping to prevent more damage.
