OBJECTIVE
To reduce the inappropriate identification of eye drops, through the use of different colors.
METHODS
A group of 34 healthy volunteers was presented to two groups of four eye drops each. All eye drops were placed in identical, unlabelled vials. In one group, all four eye drops were transparent. In the other group, each had a different color. A number was assigned to each eye drop, and the volunteer was asked to identify it by color. We measured the correct index in the identification of the eye drops of the two groups.
RESULTS
The volunteers had a level of education from incomplete junior school to complete graduate course, with 16 males (48%) and 18 females (52%), age range of 21 to 87 years. The success rate in the group of colored eye drops was 88% and, in the group of transparent, 24%.
CONCLUSION
The use of colorings in eye drops can help distinguishing the vials and preventing misidentification.
