We are now offering Sil-Ophtho H in addition to our other artificial eye lubricants. Sil-Ophtho H is a heavy viscosity silicone oil used when the medium thickness Sil-Ophtho is no longer providing you with adequate dryness relief with your eye prosthesis. It is especially helpful when you live in dry climates or work outside in windy conditions.
