The bottle has horizontal orientation, of the first and second chamber that assures a user's thumb is on the front wall and a user's fingers are on the rear wall of the bottle when dispensing. The horizontal orientation provides an ergonomically advantageous wide range of motion. The positioning of a user's thumb on the front wall of the bottle allows for design adjustments in the bottle to achieve equal dispensing from both chambers.Type: GrantFiled: August 9, 2002Date of Patent: June 24, 2003Assignee: S.C.

Publication number: 20030109390Abstract: The present invention is directed to new and improved solutions for packaging contact lenses and to methods for treating contact lenses with such solutions to improve the comfort of the lenses during wear. In particular, the present invention is directed to packing solutions comprising certain non-ionic surfactants containing a poly(oxyalkylene) copolymer and having a molecular weight of 4000 to 30,000. Such surfactants are retained on the surface of an unused lens for extended periods of time, resulting in surface modification that persists in the eye, thereby providing significant improvement in the wetting properties of fresh contact lenses used for the first time and, moreover, even several hours after lens insertion, preventing dryness and improving lubricity.Type: ApplicationFiled: July 18, 2002Publication date: June 12, 2003Applicant: Bausch & Lomb IncorporatedInventors: Anil Salpekar, Stephen Ronald Tonge
