GLASSES (PROTECTIVE EYEWEAR)
Mechatronics Department safety
rules* require that approved safety glasses be worn by every student
in the classroom when appropriate.
1 class requires ANSI approved safety
glasses (photos below).
correct type of ANSI approved safety glasses, you will not be
allowed to participate in any activity that requires them
(e.g., hands-on activities,
etc.) and may be required to leave the classroom
during that time (if no safe area is available). Activities
usually may not be "made up," so you may lose the grade
for that task if you didn't bring them.
Answers to some often-asked
questions about safety glasses:
When will I first
need safety glasses?
- For MECH 1, safety glasses
will be required by the second class session.
How often do I need to bring my safety glasses?
- Safety glasses must
be available to be worn every session.
- Class schedules may
change unexpectedly and a task that requires safety glasses may
occur without advance notice.
Where are some places I can get safety glasses?
- hardware stores
- tool outlet stores
- building supply stores
- the school bookstore.
How much do safety glasses cost?
- The cost of safety glasses
can be relatively small.
- A local "tool"
outlet sells the "wrap-around" and the "over-the-glasses"
types (see photos below) regularly
on sale for as little as two dollars plus tax.
- Wearing comfortable,
fog-free safety glasses can be an important consideration, which
may increase the cost.
How long do I have to wear the safety glasses?
- Once an activity
begins that requires safety glasses they must be
worn continuously, even if it seems that they are not needed
at that moment.
- A nearby student
may inadvertently cause something to happen that may be hazardous
to your eyes.
- Because the classroom
is full of students who's actions may pose a risk,
anyone not wearing safety glasses may be required to leave the
- If you continue in our
Mechatronics program, you will find that safety glasses are required
and used for many hours of class time. This makes it very
important to buy ones that are both comfortable and easy to
see through (clear and don't fog up).
Are safety glasses available in the classroom?
- No. The instructor
cannot lend you safety glasses.
- You're at your own risk
if you borrow safety glasses, use someone else's or use a pair found
in the room.
May I share safety glasses?
- No. You may not
share the same safety glasses with anyone during an activity.
- There must be one pair
of safety glasses per student.
- Passing them back-and-forth
is not permissible.
May I use my eyeglasses, sunglasses or motorcycle goggles instead of
- No. Your eyeglasses,
sunglasses, skiing and motorcycle goggles are not likely
- Even some cheap "dollar"
look-a-likes that say "safety glasses" may also not be
- They are certified safety
glasses only when the lenses and/or frames are
imprinted with the ANSI standard number, Z87
- When in doubt, the instructor
will check for that imprint.
What are the "correct type" of safety glasses?
- If you wear eyeglasses,
the safety glasses must be made specifically for
- Goggle-type or over-the-glasses
type safety glasses must be used by eyeglass wearers (see photos
- Safety glasses intended
for non-eyeglass wearers may not be used over or under eyeglasses.
- If you are in doubt
about a purchase, ask the teacher, and be sure to save the receipt
and packaging for a possible refund.
- Approved safety
glasses must have clear lenses. Unless there is a
medical reason to use them, dark lenses (like sunglasses) will not
be allowed for safety reasons.
What does "ANSI approved" mean?
- Safety glasses must
conform to a higher standard of impact resistance
than regular eyewear. That standard applies
to both lenses and frames.
- OSHA, the federal government
department that oversees workplace safety, has adopted safety-glass
standards established by ANSI (the private, nonprofit, American
National Standards Institute).
- Safety glasses must
pass a high mass impact test, a durability test and, for the high
impact rating, a high velocity impact test. Non-prescription
safety glasses are marked with either Z87 (basic impact)
or Z87+ (high impact).
Examples of the basic
styles of allowed safety glasses are shown below:
protective eye wear conforming to ANSI Z87.1 must be worn by every
student in the classroom any time there is a potential hazard that
could adversely affect a person’s eyes and/or face. You must
furnish your own eye protection which can be purchased at an automotive
parts retailer, hardware store or from the campus bookstore at a
