There are persons who enjoy practicing target fire of hunting as a way to spend their spare time, and many of them were confronted at some point or another with shooting safety glasses. Vision problems prevent some of them to continue these activities from a certain age. Bifocal shooting safety glasses are a way of both improving your sight and still relishing the pleasure of hunting or firing at a target.
Characteristics of Shooting Safety Glasses
This type of safety glasses consists of a pair of bifocal lenses incorporated in a sturdy polymer frame. A golden or a yellow tint is often drawn on the shooting safety glasses in order to limit glare, whereas wrong evaluation of the setting distance is prohibited by a lower bifocal point. Hence, any person that has eyesight difficulties but enjoys hunting and shooting can use these glasses to correct the respective visual disabilities.
In what concerns the fact that shooting safety glasses are colored, this has two underlying reasons:
- the coloring amplifies the outline of the object;
- the colors lower glare produced by sun or strong light, as said earlier.
These glasses are not to replace the ones prescribed for optical correction and they have to be worn only when hunting or shooting.
The Importance of Shooting Safety Glasses
The National Rifle Association is very strict when it comes to following safety guidelines for shooters. According to them, any shooting range requires eye protection which is best ensured by wearing such glasses. Thus, the occurrence of injuries as a result of discharging a weapon is avoided. Not only the shooter has to wear safety glasses, but all the persons in his vicinity too. When a weapon is fired, some fragments might fly through the air and cause injuries to the observers. By wearing safety glasses, the possibility of such event to happen is diminished.
Therefore, the major function of shooting safety glasses is to ensure impact protection. In the United Stated of America, there are three impact standards that must be applied to any protective eye-wear in order to certify its quality. These are:
- Occupational Safety and Health Administration,
- ANSI Z87 and
- MIL-V- 43511C.
The materials usually used to fabricate the protective eye-wear by most of the manufacturers are polycarbonate, SR-91 and Trivex. OSHA and the U.S military conduct tests to establish their impact resistance ratings. When one wants to buy a pair of shooting safety glasses, optical clarity and impact performance have to be taken into consideration.
