The eye and its structure :
The most common visuel defects :
The nearsightedness (myopia)
The myopic eye of the eyeball is too long built. That means that the images in
front of the retina. The myope thus sees things in the relatively near
significantly, but at a distance blurred. Depending on the degree of myopia can
be the shooter the Diopterloch, and the block or the ring is relatively clear,
but the disc blurry exercise.
The farsightedness (hyperopia)
The eyeball of uebersichtigen eye is too short built. The causes behind the
images of the retina. In hyperopia weak, it may appear that the stakeholders in
the recent years, none of this notice. Through accommodation (muscle strain) can
make this mistake, to a certain point corrected. Depending on the degree of
hyperopia, and the disc can block or ring with a large Accommodation expenditure
quite clearly seen.
Suggestions :
| Eye drop
|
Beware, the changes may cause tears films |
| Eye training | Yes, active recovery is not called eyes closes, but different Sehziele on short distance successively fix approx. 5 sec. then distanc change. Accomodation muscles are operated. |
| Alcohol
|
Caution, dangerously, bodies racts differently |
| Eyeglasses - accustomed
|
The eye does not need habituation to the lens |
| Sight
|
Not to small attitude. Rule of thumb : Too much light is better than too few |
| Filter
|
Yes, if own adaptation is not sufficient. Contras improvement however individually |
| Korn beam
|
Individuelly, broad grain better detectably, however larger side errors possible |
| Contact Lenses
|
Not suitably, interference factor light, tear film etc. |
| Means to rub
|
Ability to be likewise drunk, belive make blessed |
| Mental training
|
Yes, however a certain condition requires |
| Tablets
|
Only after medical regulation |
| Visor clip
|
Light gap should approx. 1/3 the grain width amount to |
Color filter :

To increase contrast in changing light conditions,
we recommend filter intentions

A good vision is one of the first prerequisites for optimum performance. The athletes must at every sport like Long jump, high jump, or at all ball games and all the distances to estimate accurately detect objects. Of all the sports, but certainly when shooting for the highest standards of our visual organ. The shooter must have a longer time to different distances detect very small objects, and always equal good exercise.
Minor visual defects, which in normal daily life remain mostly imperceptible, effect may be shooting at the already negative. Thus, not only to the eye but also to the necessary Sehhilfe extremely high demands. From the outset, it should be said that the shooting contact lenses are almost always inappropriate because it was based on the cornea and swim with each Eyelid impact move. This produces small optical shifts, which are the targets immediately felt bad, because the picture is different shots. In addition, the shooter over relatively long time without blinking as the target fixed. Due to the low Eyelid flapping mode frequency dries the front lens surface faster, including the optical quality of the target image suffers. As we conclude that the gunman shooting exactly visually and technically adapted needs.
The vision for changing light conditions
The conditions are changing for the shooters are often very problematic. If the athlete but to an optimum See contrast instructed. But is an ideal image is very often just a dream. From my own Shooting practice I experience again and again, that the ideal conditions a maximum of 3 - 4 times per season are available. Rather, there are disturbing light bills, back-light situations, scattered light, wind, etc. Now it is behind the weapon the right to do so. Not the desired image on, but with the given situation best possible deal. A major factor is the mental adjustment. The healthy human eye is always in a normal situation changing light conditions to adapt (That is to say: the pupil regulates the incidence of light). Certainly, it is interesting to know how much light at all on our visual organ effect.
Some examples: For the lunch time in February, the average daily light intensity about 10,000 LUX. In June and July, however, about 70,000 LUX. In September, we have from 06.00 - 12.00 an increase in the daylight intensity of 100 - 40,000 LUX to cope.
As a comparison, for a well erleuchteter workplace are about 500-1000 LUX necessary. An Indoor Shooting should 1000 LUX which after ISSF standard. The practice shows the following situation: As a rule, expresses the gunman in the so-called normal light conditions or with no light rather dull effort a good contrast picture. In bright flash disks, or even the larger problem. Quite specifically, in shallow sunlight, the glare sensation substantially greater than with a high sun. Now it is for the Protect the right thing to do.
Basic rule :
The personal feeling is dependent on several factors, age, visual defects, retinal sensitivity, adaptive ability, just to mention a few possibilities. Each eye interprets the current situation different. So each shooter must also his own personal action.
With the technical capabilities of the weapon, the gunman certain problems. The
army weapons should necessarily use iris aperture, so that the depth of focus
regulated. At sporting weapons is a ring of iris advantage. But it is with these
tools properly. Equally important, especially when the target block grain
technology.
For the different lighting conditions, with a corresponding color filter significantly improves the contrast. For the active shooter, I recommend that basically 2 filter types: The ACE blue filters suitable for light to flash and changing light. The yellow filter is especially to the light situations to their advantage. He is also suitable for the B disc. In addition, there are several intermediate hue.
The sporting weapons are integrated color filter in the iris diaphragm. This result, however, uses a big disadvantage: eg The gunman used a dark filter no matter what color to each attack, the visual organ, respectively, the color adapt. After the shooting, the weapon away from the eye, therefore, the condition changed again adapted. The eye has an extra burden to overcome.
Finally, I must emphasize again and again that every eye its individual
sensation. Each shooter must ultimately judge his personal situation. As for a
good, the other is bad.
