What method same as described above carried out, illumination is measured using illumination photometer.In addition, the specific refraction of the eyes of subject is benefit
With automatic optometry unit (refraction degree measuring device) measurement.In addition, subject is set as 18, whole subjects'
Eyesight is set as 1.0.
By the experiment, Fig. 4 and result shown in fig. 5 have been obtained.Fig. 4 be the reading face that indicates (illumination region) illumination with
The figure of relationship between reading distance (line-of-sight distance), shows the influence that lighting environment generates line-of-sight distance.In addition, Fig. 5 is
The figure for indicating the relationship between reading distance (line-of-sight distance) and the variable quantity of specific refraction shows reading distance and bears with to eyes
Correlation between load.In addition, in figures 4 and 5, reading distance (line-of-sight distance) indicates that the average value in 60 minutes is (average
Line-of-sight distance).
As shown in Figure 4, it is known that the more high then line-of-sight distance of illumination in illumination region is longer, on the contrary, in illumination region
The smaller then line-of-sight distance of illumination is shorter.That is, it is known that the posture of the more high then observer of illumination is more correct.
In addition, as shown in Figure 5, it is known that the line-of-sight distance the long, and the variable quantity of the specific refraction of the eyes for front and back of reading is smaller,
On the contrary, the line-of-sight distance the short, the variable quantity of the specific refraction of the eyes for front and back of reading is bigger.
The variable quantity of the specific refraction of eyes means greatly big to the burden of eyes.About this point, described below.
The light for entering eyes from object is imaged on the retina by adjusting lenticular expansion in people, can make eye
The focal involution of eyeball to carry out visual identity to object.Lenticular expansion is adjusted by ciliary muscle, to adjust eyes
Specific refraction.
For example, the ciliary muscle relaxation of eyes, crystalline lens becomes in the case where the focal involution of eyes object at a distance
It is thin.In this case, also small to the burden of eyes due to ciliary muscle relaxation even if the object of continuous observation distant place.
On the other hand, in the case where focal involution object on hand, the ciliary muscle tenses of eyes, crystalline lens becomes
It is thick.In this case, big to the burden of eyes due to ciliary muscle tenses when continuous observation object nearby.Due to
Reading and long lasting for observation object nearby in a period of, ciliary muscle is always nervous, therefore is terminating reading
The anxiety of ciliary muscle also continues and cannot mitigate afterwards, causes to become the state (pseudo-myopia) with high specific refraction.Also
It is to say, the variable quantity of reading front and back specific refraction means greatly big to the burden of eyes.
Thus, as shown in figure 5, the variable quantity of the specific refraction of the eyes before and after the reading of the more short then subject of line-of-sight distance
Mean that the line-of-sight distance the short then bigger to the burden of eyes more greatly.
In the present embodiment, the evaluation of illumination light (lighting environment) has been carried out using the situation as evaluation criteria.
