Know How to Remove Soft and RGP Lenses with Greater Ease

Removing contact lenses is a bit tricky for the beginners and the occasional users. There are different methods which are used to remove different kinds of lenses. In major we have two lenses Soft lenses and Gas permeable lenses. Let us see two different methods for removing these two lenses.

Pinch method to remove soft lenses: Proper washing and cleaning of the hands should be done prior to either applying or removing contacts. After washing, with the help of your left hand pull the lower eyelid downwards and try to look upwards or sideways. Using your finger tip gently slide the lens which is in the center of the eye on to the white part of your eye. After making sure that it has come out, with the help of your thumb and index finger lift the lens off the eye and remove them carefully. Also make sure that you do not have nails for your fingers so that you can save your eyes from scratching.

Finger and thumb method to remove RGP lens: In this method, before removing the lens itself you have to get ready with the other hand to catch the lens. If you are removing the lens from the right eye use your left hand should catch the lens and vice-verse. Bend yourself forward, make your hand in to a cup shape and place it right below your eye with the palm side facing up in order to catch the falling lens. Now place the finger of the other hand at the outer cornea of the eye and drag the skin towards outside. This helps the lens to loose contact with the eye. Now blink your eye and the lens will fall down in the cup shaped hand.

What ever the lens may be, the condition of the mind while removing the lens is so important. Don't do anything in a hurry or don't panic if you have failed for the first time. It is important to be calm and do the process in a smooth way.

All About Rigid Gas Permeable Contact Lenses

Rigid gas permeable lenses have distinct characteristics, which are designed to upgrade the existing hard and soft lenses. They are designed in such a way to overcome the drawbacks which people faced with those soft and hard lenses. Gas permeable lenses which are popularly called as GP lenses are made of firm plastic like that of hard lenses but still allow the oxygen to reach the eye just like the soft lenses. They do not contain water or any gel but moves every time we blink our eyes and transmits much oxygen to the eyes. Hence, they are named as gas permeable lenses.

Even though the old fashioned hard contact lenses are made of PMMA material which is of high quality they fail to transmit the oxygen to the eyes which result in other eye problems and hence those lens are a great failure. Unlike those lenses, GP lens with constant movement along with the eye transmit more oxygen to the eye and hence prevents problems caused due to contact lenses.

Few other advantages of these GP lenses are they can be designed to fit exactly to your eyes. Especially, in case of people suffering from astigmatism, they have the corneas which are not perfectly round in shape and all other lenses will not fit for them and for them these GP lenses are much useful since they can be customized according to the shape of the eye. Hence, these lenses are pretty good for people suffering with astigmatism.

Moreover, these lens are rigid and more durable when compared to the remaining two types of lenses. Because of their hard surface they can withstand any conditions and can resist deposits than the soft lenses. They are easy to handle and clean and offer more comfort while wearing and removing. Above all they are healthy to the eyes and do not affect them in anyways.
