Those who are using contact lens for the first time will have a few practical questions regarding the proper way of wearing it and the usage. Here are some tips that will answer your concerns.

The Right Way of Wearing Your Lens

The best way to place your optical lens is by sticking it to one of your fingers to form the cup that will assume the bulge of your eyeballs. Then, hold it directly against the front of your eyes to you can see the side of the cup. If the edges are flaring out, then it means you are doing it the wrong way.

If you are using the aid of a handling tint, use your fingertip to hold the lens. You will find that the tint of the lens’ edge is very visible, which isn’t the case if the lens is inverted.

Placing Your Contact Lens

Before applying the lens into your eyes, make sure that your hands are properly cleaned. Avoid using products that might adhere to the surface of the lens and could damage your eyes when used.

Before using, you can try to shake the lens case gently to loosen up the lens in case it gets stuck inside. Never attempt to pull it out using your fingers as it can damage the lens. Once loose enough, rest the contact lens in the palm of your hand and rinse it with the lens solution. After that, you can place it on a dry middle or index finger. Use your other hand to gently pull up your eyelid and pull down your lower lid. Look upward so you can properly position the lens. Make sure to place the lens on the white of the eye, nearest your ear. Allow the lens to settle by slightly rolling your eyes and blinking.

Removing Your Contact Lens

As with placing, you must also wash your hands thoroughly before removing your contact lens. Then, look upwards as you would when applying it. Pull down your lower lid so you can gently maneuver your finger inside the eye to remove the lens. Use your index finger to slightly pinch at the lens and lift it off slowly. It is highly recommended that you clip your nails to avoid hurting your eye in the process as you might accidentally hit the white of the eye instead of the contact lens in the process. Basically, it is all just a reversal of the process of applying the lens into the eye.

There are several devices sold for removing contact lens such as “plungers” but it is very easy to do on your own, provided that you properly follow the steps provided.
