Contact lenses, or rather the non-prescription ones are the latest craze in fashion. You don’t need to surgically dye your eyes (if that was possible), or color it in Photoshop to change its color. All you need to do is to buy a pair and voila! Instant eye color! Hurrah!
But trendy as it may be we forget what their original use was.
So, what are contact lenses?
Contact lenses are these small disks made from either plastic or silicone which is used to correct eye problems like nearsightedness, farsightedness, and astigmatism. People who had surgery for cataracts also use them. You can say that they are the miniature and the handier version of prescription glasses.
Okay here’s the little scientific explanation of how contact lenses stick in your eye. Contact lenses stick to the tear film, which covers the front of the eye and is responsible for making your eyes wet and well lubricated. This is done so because whenever the eyelid blinks the movement causes the lens to move slightly therefore allowing fresh tears to flow under the lens so that they won’t dry up and stick to them.
There are two types of contact lenses, the HARD and the SOFT lenses.
However, we are more familiar with the soft lenses for this is what we see in optical shops in malls and online stores. The most popular among these would be the fashion lenses or tinted soft lenses. Others would term them as cosmetic lenses.
Like most accessories and gadgets, contact lenses also have a wear and tear, in short expiration date, and will most likely come fast when used improperly. When that does happen, one can damage their eyes.
So you’re a first timer, huh? How would one know it’s inside out? How does one even put on these lenses?! It’s so hard!
The trick is to place the lens on your finger so that a cup is formed. Then hold the lens up directly in front of your eyes so you’re looking at the side of the cup. If the lens forms a “U” with the top edges flared out, it’s inside out. If it forms just a “U,” it’s in the correct position. If you’re wearing lenses with a handling tint, another way is to place the lens on your fingertip and then look down at it. The edge of a tinted lens should look very blue (or green, depending on the tint); that won’t be the case if the lens is inverted.
Some contact lenses also have laser markings on them, such as the brand name, on the edge to help you. If you can read it properly, the lens is not inside out. Don’t worry if you place a contact lens in your eye inside out. The lens will feel uncomfortable, it may sting or itch but it can’t do any damage, unless you start scratching your eyes.
From a former first time user, this indication’s a big help if you wanna be a bit wiser about lenses.
But do take note that if there are any irregularities with the lens don’t apply them just yet because there must be something wrong with them and could potentially damage your eyes.
Finally, some nuggets of wisdom: You may not get it the first time and it may take you a while to get used to it or to develop your own technique on how to put them on. After all, practice makes perfect.
