Foveated rendering technology is a mathematical model that helps accurately predict the next gaze fixation point and reduces the inaccuracy caused by blinking.
Dry Eye - Symptom Evaluation
Dry eye may be due to a decrease in tear production, alteration of the tear consistency, or faster evaporation of the tears.

‘Foveated rendering technology helps improve computational performance and eliminates issues caused by the gap between the limited capabilities of graphic processors and increasing display resolution.’
"We have effectively solved the issue with the foveated rendering technology that existed in the mass production of VR systems," researcher Viktor Belyaev, Professor at the RUDN University in Russia. Foveated rendering is a basic technology of VR systems. When a person looks at something, their gaze is focused on the so-called foveated region, and everything else is covered by peripheral vision. Therefore, a computer has to render the images in the foveated region with the highest degree of detail, while other parts require less computational powers.
This approach helps improve computational performance and eliminates issues caused by the gap between the limited capabilities of graphic processors and increasing display resolution. However, foveated rendering technology is limited in speed and accuracy of the next gaze fixation point prediction because the movement of a human eye is a complex and largely random process.
Dry Eye Syndrome - Causes, Symptoms, Diagnosis, Treatment and Prevention
Dry eye syndrome, also called keratoconjunctivitis sicca, is a progressive condition characterized by dry eyes due to the absence of tears. There are many causes and symptoms of dry eye. Dry eye syndrome is treatable.

The predictions of the model are based on the study of the so-called saccadic movements (fast and rhythmic movements of the eye). They accompany the shifts of our gaze from one object to another and can suggest the next fixation point. However, these models cannot be used by eye trackers to predict eye movements because they are not accurate enough, the team said.

Eye Allergies | Ocular Allergies - Types, Causes, Symptoms, Diagnosis, Complications, Treatment and Prevention
Eye allergy or allergic conjunctivitis occurs when the eyes come in contact with any substance that stimulates the immune system causing watery, red eyes with itchy sensation. It can usually be treated with eye drops

The new method was tested experimentally using a VR helmet and AR glasses. The eye tracker based on the mathematical model was able to detect minor eye movements (3.4 minutes, which is equal to 0.05 degrees), and the inaccuracy amounted to 6.7 minutes (0.11 degrees).

Eye Pain - Symptom Evaluation
Eye pain usually follows trauma, eye infection or inflammation of the eye and the surrounding structures. The cause of eye pain can be diagnosed based on the type of pain and associated symptoms.
