Apparatus for enhancing visual perception of selected objects in recreational and sporting activities

Claim 1

A viewing apparatus for enhancing visualization of a pre-determined target object against a background of other objects comprising: a. lens means for transmitting a high percentage of light to each eye of a user over a spectrum of wavelengths within a visible light spectrum, to define a filter spectrum; b. the lens means including optical filter means for attenuating light at wavelengths outside the filter spectrum such that the filter spectrum is broader than a target spectrum and narrower than the visible spectrum, and whereby the filter spectrum has upper and lower edges defined by wavelengths where light in the visible spectrum outside the upper and lower edges is substantially attenuated as compared to a center portion of the filter spectrum, the optical filter means having a color tint visible to the user; c. the target spectrum comprising a spectrum of wavelengths of light which emanate from the target object to define a true color of the object, the target spectrum corresponding to a relatively narrow portion of the visible light spectrum of wavelengths, and wherein the target spectrum is further defined by at least one target wavelength which corresponds to a point within the target spectrum of peak light intensity, with light intensity within the target spectrum both above and below the target wavelength being of decreased intensity compared to the target wavelength; d. the optical filter means further attenuating light such that the target wavelength is within the filter spectrum and proximate either the upper or lower edge of the filter spectrum whereby the target object is perceived by the user as having its substantially true color and background objects are perceived as having a contrasting color which is substantially the same as the color tint of the optical filter means; and e. support means for positioning the lens means between the user and the target object such that visual perception of the target object is enhanced concurrently in each eye of the user.
