Lens Shock Impact Ability Lab Testing Machine With Graphic Users
Interface
Introduction:
Lens Shock Impact Ability Testing Machine will test the impact of lenses to meet the applicable ANSI,FDA and
European requirement. All the lenses must pass an impact test,
known as the "Drop Ball Test": a 16-millimeter steel ball is
dropped onto the lens from a height of 1.27 meter
Specification:
1) 5/8-inch steel ball weighing approximately 0.56 ounce
2)Dropped from a height of 50 inches upon the horizontal upper
surface of the lens.
3)The ball shall strike within a 5/8 inch diameter circle located
at the geometric center of the lens.
4)The ball may be guided but not restricted in its fall by being
dropped through a tube extending to within approximately 4 inches
of the lens.
5)To pass the test, the lens must not fracture
2)Drop ball System
Drop ball system includes pneumatic finger, lift synchronous belt,
cleaning brush, steel ball recycling and reputing system
3) Pneumatic finger
Pneumatic finger is used to clamp and release ball.
4) Lift synchronous belt
Lift synchronous belt delivers the pneumatic finger with steel ball
to requested drop height 1.27m.
5) Cleaning brush
Cleaning brush sweep the tested lenses to recycling box
6) Steel ball recycling and reputing System
Steel ball recycling and reputing system will sort out balls from
tested lenses and return to initial drop point, wait to be clamped
by cylinder finger. Reputing system will automatically supply new
steel ball to continue testing once balls can not be returned to
initial point.
7) PLC Controler
PLC controller and touch screen panel for easy operation system
What kinds of Lens should test?
1. Q. What are the impact testing requirements for prescription (Rx)
glass lenses?
A. The manufacturer must test each finished Rx glass lens
individually for impact resistance (21 CFR 801.410(c)(3)). The lens
must be capable of withstanding the impact test provided in 21 CFR
801.410(d)(2) as described later in this document under “Testing
Apparatus and Procedure.” You should perform testing after the lens
has been edged (cut to the shape of the frame) but before the lens
is put into the frame.
2.Q. What are the impact testing requirements for non-prescription
(over-the-counter) glass lenses, e.g., magnifying spectacles and
nonprescription sunglasses?
A. You must test a statistically significant sample of
over-the-counter glass lenses from each production batch. The
sample must be representative of the finished forms as worn by the
wearer, including forms that are of minimal lens thickness and have
been subjected to any treatment used to impart impact resistance.
