Contact Lens have always been gift and a boon to patients who were using thick heavy glasses for years. One can change the cosmetic look of the face by using contact lenses, it also provides a functionally better clarity of vision and better field of vision. On insertion of contact lenses for the first time there is likely to be a little watering redness & irritation for a few minutes because of the eyes reaction to a foreign body. This should not be a cause for worry. On prolonged wear these symptoms gradually fade out and completely disappears in about a week in case of semi-soft lenses and much less time in soft lenses.
Always wash your hands with a soap and water before using the lens.
Wear the right lens first and then the left. Similarly, remove the right lens first and then left. This will prevent the lenses getting mixed up.
