Getting safety sunglasses is essential for sports requirements, but you should understand the differences between regular and sports safety glasses before making up your mind. Generally, they come with a wide array of characteristics, which is why you should learn more about them.
When choosing between two different options that you can find, it is vital to start a process based on the environment you will use them in.
By entering here, you will be able to learn more about ANSI standards in general.
Keep in mind that one of the essential standards for additional security is ANSI, which means that you will not break through lenses. At the same time, you can use them for different work environments.
Since this particular standard is based on lens dislodgement, you will not get the focus and vision the same way as sports shades.
Differences Between ASTM and ANSI Standards
ANSI Z87.1 Standard
The American National Standard Institute or ANSI Z87.1 is a standard that you need to follow when choosing equipment to provide you with occupational safety. Therefore, lenses have to withstand a 1.1-pound pointed projectile at fifty feet to obtain this particular certificate.
We are talking about the High Mass Impact Test, which is highly important for determining the best equipment to protect your eyes.
On the other hand, the second test of frames and lenses is the High-Velocity Impact Test that will require glasses to withstand an impact of a 0.25-feet diameter steel ball that fires it at 150 feet per second.
The best way to determine whether a particular frame features this standard is by checking to find Z87+, which means that it passed both tests we have mentioned above.
This particular sign should be on each frame front and temple, which is another crucial consideration to remember. When it comes to lens markings, you will notice various signs, including:
- V – It means that the lens comes with photochromic features that will provide you variable tints.
- S – This particular option means that lenses are shaded, which means that you will not get enough clarity for sports activities.
- + – Finally, this particular sign means that both lenses have passed High Impact and High-Velocity tests
On the other hand, based on the American Society for Testing and Materials or ASTM F803 is a safety standard for sports eyewear. As a result, special glasses have to withstand projectiles between forty and sixty-five millimetres at ninety miles per hour.
You can find numerous styles and options available on the market that will provide you with this particular safety for handball, tennis, paddleball, badminton, squash, racquetball, basketball, and football.
Frames should feature the brand’s name, date code, and frame style, which is highly important for prescription sports sunglasses. On the other hand, for non-prescription options, they need to feature frame style and brand name.
You can find various options the Oakley Sunglasses website that will provide you the ability to compete in different sports.
When it comes to prescription lenses, they do not require marking, but you should get a lab slip that will feature lens material, frame name, prescription, and laboratory name.
