This paper is a highlight of the results regarding the ocular temperature held so far by the scientific community. The authors developed an experimental study on a number of 20 subjects. Infrared (IR) ocular thermography determines ocular surface temperature (OST) of the eye and preorbital skin by measuring the amount of IR radiation emitted from the surface with an infrared thermal imaging camera. Noninvasive ocular thermography was first introduced in 1968 and was used to evaluate both normal and pathological conditions. For this, a FLIR Systems camera was used to capture the eye temperatures of the 20 young subjects (male, female). IR-ray thermography is recognized, being a method of analyzing the temperature of the non-invasive eyeball. Following the analysis of the experimental data, the results obtained by other previous studies were confirmed. The acquisition of corneal center temperatures (manually determined) in both eyes led to an average temperature of 34.5 °C, an inter ocular difference of 0.110 °C. Also, a maximum temperature was found in the tear duct, relative to the center of the cornea and the lateral corner. The Flir camera could also be used in the study of contactology, of the efficient adaptation of the patient with the different types of contact lenses.
