First of all, you need to wash your hands properly with soap. Make sure that there is no dust or dirt left on your hands before touching your contact lenses. After washing your hands properly, clean them.
Now you should take off lenses from your eyes gently and keep them in a container or you can hold them in your fingers. Alternatively, you can also put them on your palm.
Then pour a few drops of water into the container or on the palm of your hand where you put the lenses. Keep pouring the drops of water until the lenses get completely wet. Make sure you do not put enough water that could be spilled out of your hand.
After that, gently rub the lens into water with your finger and you will notice that the lens is getting clean and water absorbs the dust or dirt. Continue doing it for a few seconds until all dirt from the lens is removed.
Now pour in a few drops of water and again rub the lens gently which will completely wash away the dirt or dust from the lens. Now you can use these contact lenses as they are ready for use.
