Abstract

A method for providing eyeglasses for persons of limited means which includes the steps of providing an eyeglass frame including left and right circular lens support rims, a width-adjustable bridge and a pair of adjustable temples and a plurality of plastic preformed circular lenses, each fitting into the lens support rims and having two lens components, a spherical lens component and a cylindrical lens component. A left and a right preformed circular lens are selected from the plurality of preformed circular lenses which approximate the preferred spherical and cylindrical lens corrective strengths, and these are inserted and rotated in the rims, then it is determined whether the selected lenses provide adequate vision correction. These steps are repeated until the selected left and right preformed circular lenses provide adequate vision correction to the person being fitted.

Claims

1. A method for providing eyeglasses for persons of limited means comprising the steps:

providing at least one eyeglass frame having a frame front including left and right circular lens support rims and a width-adjustable bridge extending between and connecting said left and right circular lens supports and a pair of adjustable temples mounted on opposite sides of said frame front and extending rearwards therefrom to extend over the ears of the wearer;

providing a plurality of plastic preformed circular lenses each having a center axis and a diameter to fit and be secured within said two circular lens support rims, each of said plurality of circular lenses having two lens components, a spherical lens component having a predetermined strength and a cylindrical lens component having a predetermined strength and orientation, said plurality of preformed circular lenses including lenses having different strengths of spherical and cylindrical lens components;

approximating via visual acuity examination of a person to be fitted for eyeglasses the preferred spherical lens corrective strength to correct the refractive error of the eye and the preferred cylindrical lens corrective strength and orientation to correct the astigmatism of the eye to provide corrected vision for the person;

selecting a left and right preformed circular lens from said plurality of preformed circular lenses, said left and right preformed circular lens having spherical and cylindrical lens strengths approximating the preferred spherical and cylindrical lens corrective strength for the left and right eyes of the person being fitted for eyeglasses;

inserting said selected left and right preformed circular lenses into said two circular lens support rims of said at least one eyeglass frame;

rotating said selected left and right preformed circular lenses about said center axis within said two circular lens support frames to generally align said cylindrical lens alignment component for correction of the astigmatism for the eye;

placing said at least one eyeglass frame including said selected left and right preformed circular lenses onto the head of the person being fitted with said eyeglasses;

adjusting said width-adjustable bridge and said adjustable temples to generally align said at least one eyeglass frame on the head of the person being fitted such that selected left and right preformed circular lenses are generally aligned with the eyes for which vision is to be corrected;

determining if the selected left and right preformed circular lenses provide adequate vision correction to the person being fitted with said eyeglasses; and

repeating said selecting, inserting, rotating, placing, adjusting and determining steps until said selected left and right preformed circular lenses provide adequate vision correction to the person being fitted with said eyeglasses.

2. The method of claim 1 wherein each of said plurality of plastic preformed circular lenses further comprises an insignia imprinted thereon which delineates the alignment of the cylindrical lens component within each of said plurality of plastic preformed circular lenses thereby facilitating rotation of said lenses to a preferred alignment of the cylindrical lens component of the preformed circular lens in order to provide astigmatism correction for the individual being fitted for the glasses.

3. The method of claim 1 wherein said at least one eyeglass frame is constructed of plastic.

4. The method of claim wherein said step of determining if the selected left and right preformed circular lenses provide adequate vision correction to the person being fitted with said eyeglasses comprises having the person being fitted read from an eye chart to determine their corrected level of nearsightedness or farsightedness and then view a spoke diagram to relate the direction and level of corrected astigmatism in the person being fitted for eyeglasses.

5. A method for providing eyeglasses for persons of limited means comprising the steps:

providing at least one plastic eyeglass frame having a frame front including left and right circular lens support rims and a width-adjustable bridge extending between and connecting said left and right circular lens supports and a pair of adjustable temples mounted on opposite sides of said frame front and extending rearwards therefrom to extend over the ears of the wearer;

providing a plurality of plastic preformed circular lenses each having a center axis and a diameter to fit and be secured within said two circular lens support rims, each of said plurality of circular lenses having two lens components, a spherical lens component having a predetermined strength and a cylindrical lens component having a predetermined strength and orientation, said plurality of preformed circular lenses including lenses having different strengths of spherical and cylindrical lens components, each of said plurality of plastic preformed circular lenses further including an insignia imprinted thereon which delineates the alignment of the cylindrical lens component within each of said plurality of plastic preformed circular lenses thereby facilitating rotation of said lenses to a preferred alignment of the cylindrical lens component of the preformed circular lens in order to provide astigmatism correction for the individual being fitted for the glasses;

approximating via visual acuity examination of a person to be fitted for eyeglasses the preferred spherical lens corrective strength to correct the refractive error of the eye and the preferred cylindrical lens corrective strength and orientation to correct the astigmatism of the eye to provide corrected vision for the person;

selecting a left and right preformed circular lens from said plurality of preformed circular lenses, said left and right preformed circular lens having spherical and cylindrical lens strengths approximating the preferred spherical and cylindrical lens corrective strength for the left and right eyes of the person being fitted for eyeglasses;

inserting said selected left and right preformed circular lenses into said two circular lens support rims of said at least one plastic eyeglass frame;

rotating said selected left and right preformed circular lenses about said center axis within said two circular lens support frames to generally align said cylindrical lens alignment component for correction of the astigmatism for the eye;

placing said at least one plastic eyeglass frame including said selected left and right preformed circular lenses onto the head of the person being fitted with said eyeglasses;

adjusting said width-adjustable bridge and said adjustable temples to generally align said at least one plastic eyeglass frame on the head of the person being fitted such that selected left and right preformed circular lenses are generally aligned with the eyes for which vision is to be corrected;

determining if the selected left and right preformed circular lenses provide adequate vision correction to the person being fitted with said eyeglasses; and

repeating said selecting, inserting, rotating, placing, adjusting and determining steps until said selected left and right preformed circular lenses provide adequate vision correction to the person being fitted with said eyeglasses.

6. The method of claim 5 wherein said at least one eyeglass frame is constructed of plastic.

7. The method of claim 5 wherein said step of determining if the selected left and right preformed circular lenses provide adequate vision correction to the person being fitted with said eyeglasses comprises having the person being fitted read from an eye chart to determine their corrected level of nearsightedness or farsightedness and then view a spoke diagram to relate the direction and level of corrected astigmatism in the person being fitted for eyeglasses.
