How to wear contact lens?
First step is to rinse your hands with anti-bacterial soap or solution (NOT SANITIZER), wash them of well with water, so that no soap remains on your hand and completely drying them off before handling contacts with towel (would recommend not to use tissues as they leave some particles, which may stick onto your contacts and you will have foreign body sensation while you are having them on).
Contact lenses usually comes in sachets like shown below:
Peel of the foil covering
And take out lenses carefully from the sachet (remember to keep your nails cut while handling them, as they are very soft, and there is more chance of the contacts getting damaged)
Then place them on your index finger to check if they are straight or inverted.
To check them if they are straight or inverted keep them in front of your eyes and observe their shape.
An inverted contact lens would look like a saucer
A straight contact lens would look like a bowl
Positioning your hands
Many people come up with their own style in wearing contacts. But the common and most taught method by practitioners is like below:
Whether you are a lefty or a righty, keep the contacts on your dominant hand's index finger. Bring other hand's index, middle and ring finger together from backwards of your head (not sideways, as it may block your view of looking at the mirror) to hold the upper lid's margin.
Now use your dominant hand's little, ring and middle finger to hold the lower lid's margin while you have the contacts on the index finger. Hold in such a way that the index finger is right in front of your eye.
Move your index finger forward to make the contacts touch your eye. Do not leave your hand's positions till the lens has properly stuck to your eye. After the lens is placed, while your hands remain holding your eyelids, look down and leave the lower lid first and then upper lid. Now the contact lenses will be perfectly placed onto your eye.
Removing contact lenses:
Hand positions remain same. Only index finger was used while wearing them, now while removing, you also have to use your thumb finger along with index finger to pinch the contact lenses out.
Please note, Serious complications because of using contact lens only arise when one doesn't maintain hygiene. Maintaining hygiene is essential everywhere. It plays an important role in keeping our bodies healthy. Our surroundings have many disease-causing micro-organisms along with the good ones, which if comes in contact with us, may cause serious illness. We take bath daily and wear washed clothes daily to avoid skin infections. We wash our hands before we eat food, so that harmful bacteria's or viruses don't enter our body. Just think how important is it to wash our hands and the contact lenses we wear on our eyes.
