Ridgic Gas Permeable Lens Handling Advice
|
Much of the advice for RGP and specialist lenses is similar to that of Soft lenses. The major differences being in the removal and cleaning solutions. It is not necessary to check the lens for it's correct shape as the RGP lenses are not flexible and can not be turned inside out.
Insertion is performed similarly to soft except that it is important to place the lens centrally on the eye, over the pupil. If not, or if you dislodge your lens during wear then it will have to be gently coerced back to the centre by manipulating your eyelids, using a mirror, to push the lens from the white of you eye to the area over you pupil. |

Removal is quite different. The idea here is to "tiddly-wink" the lens off your eye by gently pressing your eyelids towards the eye and together thus pushing them under the edges of the lens and popping it off the eye. Be careful as the lens can jump off the eye by some distance. It is often useful to do this over a clean white towel as the lenses are generally tinted a light shade, usually blue, to enable you to see the lens if dropped. Do not use tissue as the lint in the tissue sticks to the lens and can cause severe discomfort if then inserted into the eye. An easier way can be to open you eye wide and use your forefinger to gently pull the corner of your eye nearest your ear towards the top of your ear (this tightens your eyelids) and then blink forcing the lens off the eye.
Cleaning your lenses
Cleaning the lenses is much the same as soft lenses, however, the solutions can be different. When purchasing solutions it is important to check the bottle to make sure that it is compatible with RGP lenses. most solutions have a two step system, one solution for the rub and rinse stage and another to soak the lenses overnight. This is because the lenses are more durable and are disposed of less regularly than n soft lenses, this means that proteins from the tears can build up over time, therefore, a stronger cleaning agent is required to keep the lenses clean and crisp. You can even buy protein remover solutions/tablets if the lenses become very heavily deposited.
