Role of FDA in optometry
Protects public health. Ensuring safe medical devices such as glasses, lenses and CLs.
They write the impact resistance standards!
Who writes the impact resistance standards?
FDA
Drop ball test
- When did it start
- requirements
- by who?
1972
FDA
5/8 inch steel ball weighing 0.56 Oz, dropped from 50 inches.

Legally, it can be seen as the standard of care. Sometimes, OSHA will adopt ANSI standard as regulation. In that case, it is no longer voluntary.
ANSI standards we need to know.

Ansi Z80.1-2015 prescription ophthalmic lenses recommendations
Each variable of a spec lens Rx has a range of tolerance.
Sphere
- under 6.50D +/- 0.13D
- Above 6.50D +/- 2%
Cyl power
- Under 2.00DC +/- 0.13D
- 2.00 to 4.50 DC +/- 0.15
- Greater than 2.50DC +/- 4%
Cyl axis- as cyl goes up, tolerance goes down.
Add power
- under 4.00D +/-0.12 D
- Above 4.00D +/- 0.18 D
Ansi Z80.1-2015 prescription ophthalmic lenses tolerance for axis
0-0.25: 14 degree
- 25-0.50: 7 degree
- 50-0.75: 5 degree
- 75-1.50: 3 degree
- 50 or more: 2 degree
Requirements for polarization axis location
Within 3 degrees
OSHA mission
Creates and enforces regulations.
To ensure safe and healthful working conditions for men/women by setting and enforcing standards. Provide training, education.
Has the power to make regulations- make standards mandatory
Diff between ANSI and OSHA
