Novel vision monitoring, screening, and testing tools and help-seeking enablers that may be used individually as or in combination with other vision monitoring and screening testing systems that improves patients' ability to recognize the onset and progression of visual changes over time. Patients' ability to identify acute or chronic visual conditions on their own may drive earlier help-seeking behavior by the patient, enable earlier clinical diagnosis by an eye care specialist, and therefore resulting in earlier treatment and reduced likelihood of severe vision loss.

A tamper evident closure (1) includes a housing (5) containing a blister pack (2) and a substrate (3), wherein the blister pack (2) contains a first reagent which is visible prior to first opening and the substrate (3) contains a second reagent. First opening of the closure ruptures the blister pack thereby exposing the first reagent to the second reagent and effecting a reaction that causes a visual change that signals the closure has been opened. The tamper evident closure of the present invention is primarily intended to be used as an anti-counterfeit measure on a spirit or pharmaceutical bottle. In the preferred embodiment, the closure incorporates a liquid that when brought into contact with a reagent chemical contained in an absorbent pad, effects an irreversible color change. This color change will indicate to a consumer the bottle has been previously opened or tampered with. The design makes it very difficult for a counterfeiter to cover up or eradicate the visible effects. In particular, the only way a counterfeiter could do this would be to put in a replacement blister and an absorbent pad. Filling a blister pack with a liquid is a highly specialist task which makes replication very difficult. The ability to control the color change to complement the branded goods provides a way of building up consumer recognition of the product and thereby establishing confidence in those products that carry the tamper evident closure of the present invention.

A system for teaching music with input and output devices, musical representations presented on vertically and horizontally oriented musical staffs, output responsive to selective application of input data, confirmation of propriety of input choice, and scrolling presentation of sequential musical representations constituting music. A method to develop a positive association of correct learning input to music representation presented and a negative association of improper response, to music presented in a scrolling manner along a center bar for timing visual change in musical representation upon input. Musical representations such as notes, lines and bars may be presented and the user is required to make choices through input devices to correctly identify or play the musical representation. The system and method use both visual and audio responses to input and uses color and graphical associations between the staff and notes to teach intervals and music.
