good drops strange bottle [SEP] the drops do seem to lubricate my eyes but the delivery system for the drops themselves is the worst i have encountered why not just a simple drip bottle like most others i have to use them in a magnifying mirror operating the plunge system with both hands and still i miss the mark occasionally and that is irritates me because they are so expensive these would be fine if you were confined to lying in bed and had to have someone else put drops in your eyes
