The FDA (Food and Drug Administration) ✔Correct Answer-? classifies lens material by how
much water is in it and by the electronic charge. The water is either low or high, and
percentages are given. The electronic charge is indicated with ionic or non-ionic. The materials
are in four groups as follows:
The FDA classifies lens material by four groups as follows: ✔Correct Answer-Group 1-low
water < 50% water, non-ionic polymers (this group includes silicone hydrogel polymers)
Group 2- high water > 50% water, non-ionic polymers
Group 3- low water < 50% water, ionic polymers
Group 4- high water > 50% water, ionic polymers
The FDA tests disinfectants for their successfulness against these four microorganism groups:
✔Correct Answer-•gram-positive cocci
•gram-negative rods
•yeast
•fungi
"disposable lenses" ✔Correct Answer-The FDA classification for ? means the lens is disposed
of after removal.
extended wear (EW) ✔Correct Answer-The FDA classification for ? is 1 week,
Continuous wear (CW) ✔Correct Answer-refers to wearing contact lenses both during the day
and while sleeping for periods of up thirty days and nights consecutively; however the FDA still
recommends an overnight removal of continuous wear every 6 nights/7 days.
Good Manufacturing Practices (GMP) ✔Correct Answer-standards is that part of quality
assurance which ensures that medicinal products are consistently produced and controlled to
the quality standards appropriate to thei intended use and as required by the marketing
authorization (MA) or product specification. GMP is concerned with both production and quality
control.
FDA approval for marketing ✔Correct Answer-All materials are tested, evaluated, and
quarantined until all of the standards have been met. Lens blanks are inspected, tested, and
quarantined until all of the standards are met and documented. Inspection continues to happen
through all stages of production.
, HIPAA ✔Correct Answer-The Health Insurance Portability and Accountability Act of 1996
("HIPAA") authorized the Department of Health and Human Services to adopt regulations to
require certain health providers to limit the use and disclosure of protected health information.
The regulations became effective on April 14, 2003.
FCLCA ✔Correct Answer-The Fairness to Contact Lens Consumers Act became law on
February 4, 2004. The Act mandates that eye care practitioners, including optometrists, release
contact lens prescriptions to their patients. It also requires contact lens sellers to verify the
validity of contact lens prescriptions before releasing contact lenses to consumers.
FTC ✔Correct Answer-The Federal Trade Commission enforces both the Contact Lens Rule
and the Eyeglass Rule. These Rules require that eye care providers give their customers copies
of their prescriptions: Contact lens prescriptions must be given to the customers once the lens
fitting is complete; eyeglass prescriptions must be given to customers at the end of the eye
exam.
CDC ✔Correct Answer-The Centers for Disease Control and Prevention is working with the
Food and Drug Administration (FDA), eye care providers, contact lens and product
manufacturers, and academic partners to develop messages about the healthy wear and care of
contact lenses.
OSHA ✔Correct Answer-The United States Occupational Safety and Health Administration is
an agency of the United States Department of Labor. Congress established the agency under the
Occupational Safety and Health Act, which President Richard M. Nixon signed into law on
December 29, 1970. OSHA's mission is to "assure safe and healthful working conditions for
working men and women by setting and enforcing standards and by providing training,
outreach, education and assistance".
Snellen chart ✔Correct Answer-is an eye chart used by eye care professionals and others to
measure visual acuity. ? are named after the Dutch ophthalmologist Hermann Snellen who
developed the chart in 1862.
The ? is placed at a standard distance: 20 ft in the US.
acuity chart ✔Correct Answer-The symbols on an ? are formally known as "optotypes". In the
case of the traditional Snellen chart, the optotypes have the appearance of block letters, and
are intended to be seen and read as letters.
ten Sloan letters ✔Correct Answer-Only the ten Sloan letters C, D, E, F, L, N, O, P, T, Z are used
in the traditional Snellen chart. The perception of five out of six letters (or similar ratio) is
judged to be the Snellen fraction.
