[metewand]
So, in the present embodiment, the good and bad metewand as evaluation illumination light L, has used average line-of-sight distance
From more short then to the bigger such benchmark of burden of the eyes of observer, but the benchmark is to be based on being carried out by present inventor
Following experiment result obtained from.
Present inventor is directed to the lighting condition of illumination light and the relation between the burden of eyes is tested.
In this experiment, carry out reading and be used as visual task.In addition, one of lighting condition as illumination light, use and " shone
Degree ".
Specifically, as shown in Figure 1, the subject that sit down, please on chair reads under the lighting environment of fixed illumination puts
Put the book of the illumination region 310 (reading face) on desk 300.In this case, for each subject, before visual task
After the specific refraction that eyes are measured (before reading), the visual task (reading) of asking each subject to carry out 60 minutes, and regarding
Measure the specific refraction of eyes after feel operation (after reading) again.That is, before and after having obtained the visual task of set time
Specific refraction variable quantity.In addition, in visual task, with 1 second for interval measurement line-of-sight distance X (reading distance), and calculate
Go out average line-of-sight distance Xa.
Illumination light L illumination be respectively 200lx, 900lx, 1400lx it is each in the case of carried out above-mentioned experiment respectively.
That is, tested for 3 kinds of lighting sources 200 (desk lamp).In this experiment, line-of-sight distance X measurement is to pass through
What method same as described above was carried out, illumination is measured using illumination photometer.In addition, the specific refraction of the eyes of subject is profit
With automatic optometry unit (refraction number of degrees measurement apparatus) measure.In addition, subject is set as 18, whole subjects'
Eyesight is set as 1.0.
By the experiment, the result shown in Fig. 4 and Fig. 5 has been obtained.Fig. 4 be the reading face that represents (illumination region) illumination with
The figure of relation between reading distance (line-of-sight distance), show lighting environment on influence caused by line-of-sight distance.In addition, Fig. 5 is
The figure of relation of the reading distance (line-of-sight distance) between the variable quantity of specific refraction is represented, the distance that shows to read to eyes with bearing
Correlation between load.In addition, in figures 4 and 5, reading distance (line-of-sight distance) represents 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 line-of-sight distance is more long, and the variable quantity of the specific refraction for front and rear eyes of reading is smaller,
On the contrary, line-of-sight distance is more short, the variable quantity of the specific refraction for front and rear eyes of reading is bigger.
The variable quantity of the specific refraction of eyes means greatly big to the burden of eyes.On this point, described below.
People makes the light for entering eyes from object be imaged on the retina by adjusting lenticular expansion, can make eye
The focal involution of eyeball to carry out visual identity to object.Lenticular expansion is adjusted by ciliary muscle, so as to adjust eyes
Specific refraction.
For example, in the case of the focal involution object a long way off of eyes, the ciliary muscle relaxation of eyes, crystalline lens becomes
It is thin.In this case, even if the object of continuous observation distant place, due to ciliary muscle relaxation, therefore it is also small to the burden of eyes.
On the other hand, in the case of focal involution object on hand, the ciliary muscle tenses of eyes, crystalline lens becomes
It is thick.In this case, when continuous observation object nearby, due to ciliary muscle tenses, therefore it is big to the burden of eyes.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 relaxed afterwards, causes to turn into the state (pseudo-myopia) with high specific refraction.Also
It is to say, the variable quantity of specific refraction means greatly big to the burden of eyes before and after reading.
Thus, as shown in figure 5, the variable quantity of the specific refraction of eyes before and after the reading of the more short then subject of line-of-sight distance
Mean that line-of-sight distance is more 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 metewand.
