In general, removal is easier than insertion. Lenses are removed, not with the fingers but with the lid margins. When you are wearing lenses your lids, on closing, slip easily over the lens to be in front of it. Indeed, for most of the time your upper lids will be covering the upper part of the front surface of the lenses so that when your eyes close, the lids simply slip down over the front surfaces.

When you are able, quite happily, to look straight ahead with wide open lids while touching the centre of the contact lens, you are in a good position to remove the lens.

Sometimes the people who need contact lenses most are those who may have the greatest difficulty in inserting and removing them. This seems a good place to deal with some of the problems such people have in inserting lenses, and how these may be relieved.
