Abstract
A visual field observation training lens is disclosed, along with corresponding training eyewear. An associated method for training visual observation toward a designated field of view is provided.
Claims20
A visual field observation training lens comprising:
- a total surface area;
- a first transparency region that is disposed at an upper portion of the visual field observation training lens;
- and
- a second transparency region that is disposed at a lower portion of the visual field observation training lens;
- wherein the second transparency region is less transparent than the first transparency region,
- wherein the visual field observation training lens comprises a top edge portion, a bottom edge portion that is disposed substantially opposite to the top edge portion, a first lateral edge portion, and a second lateral edge portion that is disposed substantially opposite to the first lateral edge portion,
- wherein an upper edge of the second transparency region comprises a delineation line at an interface between the second transparency region and the first transparency region, and
- wherein the delineation line of the second transparency region that is disposed at the lower portion of the visual field observation training lens extends horizontally across the visual field observation training lens from the first lateral edge portion to the second lateral edge portion.
5 more elements
A visual field observation training lens comprising:
- bifurcated tinting,
- wherein a lower portion of the visual field observation training lens is more tinted than is an upper portion of the visual field observation training lens,
- wherein the bifurcated tinting of the visual field observation training lens comprises a demarcation boundary line at an upper edge of the lower portion that is more tinted, such that there is a significantly noticeable difference in observability between the lower portion that is more tinted and the upper portion,
- wherein the visual field observation training lens comprises a top edge portion, a bottom edge portion that is disposed substantially opposite to the top edge portion, a first lateral edge portion, and a second lateral edge portion that is disposed substantially opposite to the first lateral edge portion,
- wherein the demarcation boundary line at the upper edge of the lower portion that is more tinted extends horizontally across the visual field observation training lens from the first lateral edge portion to the second lateral edge portion,
- wherein the visual field observation training lens defines a nose cutout, and
- wherein the demarcation boundary line at the upper edge of the lower portion that is more tinted runs adjacent to an apex of the nose cutout.

A visual field observation training lens comprising:
- a total surface area;
- a first transparency region that is disposed at an upper portion of the visual field observation training lens;
- and
- a second transparency region that is disposed at a lower portion of the visual field observation training lens;
- wherein the second transparency region is less transparent than the first transparency region,
- wherein the second transparency region comprises 10% to 70% of the total surface area of the visual field observation training lens,
- wherein the visual field observation training lens comprises a top edge portion, a bottom edge portion that is disposed substantially opposite to the top edge portion, a first lateral edge portion, and a second lateral edge portion that is disposed substantially opposite to the first lateral edge portion,
- wherein an upper edge of the second transparency region comprises a delineation line at an interface between the second transparency region and the first transparency region,
- wherein the delineation line of the second transparency region that is disposed at the lower portion of the visual field observation training lens extends horizontally across the visual field observation training lens from the first lateral edge portion to the second lateral edge portion, and
- wherein the delineation line comprises at least one of (i) a straight line and (ii) an arched line.
