Abstract: The disclosure relates to the use of contact lenses for treating ophthalmologic conditions, such as presbyopia, induced myopia, computer vision syndrome, insufficient accommodation, or a condition associated with insufficient accommodation. The contact lens may be selected based on a measured sagittal depth and/or eccentricity of the cornea. When fitted, fluid may accumulate between the cornea of the eye and the contact lens. The lens may exhibit a sufficient amount of apical clearance such that when the wearer blinks, the lens moves no more than 1 mm on the eye. The lens may be structured such that bubbles greater than 0.5 mm in diameter are prevented from forming between the contact lens and the eye. The contact lens may be used in combination with a suitable bioactive agent providing for enhanced visual correction.

Abstract: A pair of glasses has a glasses body and an adjusting structure. The glasses body has a lens frame and a nose pad. The nose pad is combined with the lens frame by two sliding slices and two tracks. The adjusting structure is mounted between the lens frame and the nose pad and has a first engaging block, a second engaging block, and a stopping block. The first engaging block and the second engaging block can be engaged with each other to keep the nose pad from separating from the lens frame. The stopping block is mounted to form a friction between the nose pad and the lens frame. The nose pad can be precisely adjusted and fine-tuned relative to the lens frame because of the sliding slices, the tracks, and the stopping block.

Abstract: A visual display assembly adapted for use as an anti-counterfeiting device on paper currency, product labels, and other objects. The assembly includes a film of transparent material including a first surface including an array of lenses and a second surface opposite the first surface. The assembly also includes a printed image proximate to the second surface. The printed image includes pixels of frames of one or more images interlaced relative to two orthogonal axes. The lenses of the array are nested in a plurality of parallel rows, and adjacent ones of the lenses in columns of the array are aligned to be in a single one of the rows with no offset of lenses in adjacent columns/rows. The lenses may be round-based lenses or are square-based lenses, and the lenses may be provided at 200 lenses per inch (LPI) or a higher LPI in both directions.
