Inserting and removing contact lenses - By: RandaFritch

Nowadays, many people use contact lenses to get vision correction, although they may not be clear how this correction works. As a small, round and transparent disc, a contact lens requires some skills of inserting and removing.

The eye¡¯s structure also plays an important role in the lens fitting. The eye¡¯s moisture acts as an adhesive and the eyelids slightly press the lens and hold it in place. In addition, the blinking of the eyes helps the lens keep clean. The fitting of a lens has still other requirements. In detail, the inside of the lens should perfectly fit the corneal surface and the outer surface should meet with the wearer¡¯s prescription.

Contact lenses on the eyes help the natural lens refocus the light rays to provide clear and crisp vision. Without vision correction from eyeglasses or contact lenses, blurry vision may occur. Another aspect is lens insertion and removal, which are usually routines for contacts wearers every morning and evening.

Before inserting contact lenses, a wearer should be clear about which eye should be applied first and maintain this order every day. The two lenses can not be interchangeably inserted into the eyes. That wrong application may significantly increase the risk of discomfort and even infection. Some other preparations are needed, such as rolling up the sleeves, cleaning the eye area, washing hands and so on.

Then a wearer can take a lens out of the case. Apply some rinsing solution after balancing it on the tip of the index finger. Control the blinking and use the free hand to lift the upper eyelid slightly. The middle finger of the other hand can be used to pull down the lower eyelid. Place the lens onto the center of the eye and it will adjust its position during the wearer¡¯s blinking. The other eye just needs a similar process.

Lens removal also needs hygiene required by lens insertion. A wearer should look into a mirror and move the eyelids away from the lens. Soft lens should not be grabbed so that a wearer can slightly push it and the lens buckles up. The wearer should push a rigid lens to the side and the lens will fall out while blinking. The removed lens should be carefully rinsed and cleaned before being put back in the case.

For details and further instruction of lens insertion and removal, contacts wearers can visit a doctor, who will give a training session.
