First slide it off-centre and allow it to slide back into place. If it is still uncomfortable, remove the lens and rinse it thoroughly with saline or a solution recommended by your Optometrist / Ophthalmologist. If you insert a lens that is inside out it may feel uncomfortable. Remove the lens and check the shape. If you can’t see clearly, the lens may have fallen out when you blinked if it wasn’t properly in place. To find the lens, look first on your eyelashes or cheek, or on the cloth in front of you. Rinse the lens thoroughly with saline or a solution recommended by your Optometrist / Ophthalmologist. Always carry your lens case filled with fresh soaking solution or saline unless you wear daily disposable lenses. Keep your spectacles with you at all times.
