Method for facilitating pinhole effect and tool to manipulate eyelash spacing for pinhole effect

A method of compensating for a refractive error, comprising:

• manipulating eyelashes on an individual to project into a line of sight of an eye at least when an eyelid from which the eyelashes extend is partially closed or when the eye is moved relative to the eyelid, wherein manipulating the eyelashes includes curling upper eyelashes downward;
• further manipulating at least one of spacing, orientation, direction, contour or shape of the eyelashes on the individual to create a space between the eyelashes;
• inserting an aperture structure containing a circular aperture into the space to create an optical effect that improves visual acuity when the eyelashes containing the circular aperture project into the line of sight;
• and
• providing a training instruction to the individual to position at least one of the eyelid and the eye such that the manipulated eyelashes containing the circular aperture project into the individual's line of sight to obtain the optical effect that improves visual acuity when desired.
