Introduction:
The energy that reaches the Earth is composed of light waves of different length and energy charge. Ultraviolet rays remain outside the visible spectrum and, in case of absence of protective habits and in excessive doses, they are a source of damage that can be irreversible.
Aim:
The aim of this article is to present the results obtained with a camera for the detection of changes on the eye surface and the results from a survey regarding people’s awareness of the effects of UV radiation.
Materials and Methods:
The current study is randomized and presents the results obtained from 120 participants, with a mean age of 50.03 years, SD +/- 14.279, of which men—71.67%, women—28.33%. All were provided with informed consent and a questionnaire about age, occupation, and the methods they use for UV eye protection, after which a complete eye examination was performed and the anterior ocular surface was photographed with the UV change detection camera.
Results:
In some of the participants—40.83% (n = 49), with a mean age of 33.45 years, SD +/- 12.48, no areas of conjunctival autofluorescence (CUVAF) were detected. In 59.17% of the participants (n = 71), with a mean age of 45.42 years, SD +/- 13.23, areas with changes on the anterior ocular surface were observed. As the age increased, there was also an increase of the changes both in area and intensity. The results of the survey show relatively low levels of awareness about UV light.
Conclusion:
The method of detection of conjunctival autofluorescence can be used as an objective marker for changes in the anterior ocular surface. Increasing awareness among the population can reduce the incidence of a number of diseases of the ocular surface.
