JPS6111722A - Special lens for spectacles and spectacles for operator of computer - Google Patents

Abstract

PURPOSE:To maintain the light made incident on the eyeballs to be constant and to cut the incident of harmful light by using polarizing lenses for the lenses of spectacle. CONSTITUTION:A specific polarizing film 2 is manufactured in accordance with the respective astigmatism angles of the right and left eyes of an operator's naked eyes and is adhered tightly to the lens 1 for spectacles to manufacture each one piece of specific polarizing lenses, thereby forming the spectacles for the operator of a computer. The light made incident on the lenses is thus made constant and the light such as irregular reflected light is cut. The asthenopia of the operator for the computer is thus considerably decreased and the weakening of the eyesight is prevented.

Description

DETAILED DESCRIPTION OF THE INVENTION This invention aims to prevent asthenopia and visual acuity caused by computer operations (in severe cases of serious illness, due to stress accumulation, dizziness, A special lens for operators (Claim 1) devised as an effective countermeasure for people who complain of headaches and nausea (Claim 1) and glasses using the W lens (Claim 2)
It is.

The computer operator can read the characters on the display screen,
The operator must stare at a display of figures and other objects while typing on a key board over and over again for a long time, but the light waves of the electronic signals that display the characters, figures, etc. on the display screen enter the operator's naked eye and interfere with the eyeballs. When they converge on the macula, the operator is required to decipher and understand them (in the process, the operator must continue to use the optic nerve to its limits).

Not only that, but electronic waves repeat moment-by-moment fluctuations in strength and weakness, so 1. The brightness of the electronic display is uneven, the display is unstable due to oscillations and vibrations, and furthermore, the infrared rays and solar rays emitted from the display screen enter the operator's eyes.

These factors combine to cause eye strain, weakened vision, and physical exhaustion.

The purpose of this invention is to stabilize the amount of light that enters the eyeballs and cut out harmful light by using special lenses (polarized lenses) for the lenses of glasses.

Additionally, by coating the lens surface, it is possible to cut out infrared rays and radiant rays emitted from the display screen.

This invention measures the astigmatism angle of the left eye and the right eye of the operator's naked eye, and manufactures a specific polarizing film for each based on the calculated astigmatism angle,
These two types of polarizing films are bonded one by one to eyeglass lenses in order to make each specific polarized lens, and this specific polarized lens can be used for computer operators. The glasses should be suitable.

By measuring and calculating the distortion on the eyeball of each operator's naked eye (left eye, right eye, respectively), that is, the astigmatism angle, and using a lens with a specific polarizing film adhered based on the calculated astigmatism angle. , the incident light can be made constant, and light such as diffusely reflected light can be cut.

The special lens according to the present invention and the glasses using the special lens significantly reduce eye strain of a computer operator using the special lens, and are useful for preventing deterioration of visual acuity.

[Brief explanation of drawings]

Figure 1 shows the lens assuming an astigmatic angle of 900. Figure 2 shows the lens that assumes an astigmatic angle of 900.
The longitudinal cross-sectional view of the exploded part in Figure 1 is: The eyeglass lens 2 is a polarizing film (a specific polarizing film adapted to the astigmatic angle of the operator's naked eye). Figure 3 is a lens assuming an astigmatic angle of 600. Figure 4 is
