Purpose
The objective of this study is to evaluate the effect of mixed reality (MR) glasses on visual fatigue after prolonged use in different tasks and compare them with the results obtained after using screens, with the aim of determining their safety over time.
Setting
This study supports the safety of the use of MR glasses in the adolescent population at an ophthalmological level, and may even represent a potential advantage over conventional screens, by reducing dry eye symptoms.
Methods
A parallel group randomized clinical trial was conducted in which two study arms were compared. Patients were randomized into 2 study groups, only differentiated in the order of use of MR glasses and conventional screens. They then underwent 45 minutes of using MR glasses (Oculus QuestPro) or conventional screens (Samsung 14” Tablet) depending on their assigned group. Visual acuity, Ocular Surface Disease Index (OSDI), intraocular pressure (IOP), Tear Breaking Time (TBUT), conjunctival hyperemia, accommodation, meniscus height, and stereoscopic vision testhe (Test of Nederlandse Organisatie, TNO)
Results
Regarding the use of MR glasses, the OSDI score was the data that showed the greatest difference (p<0.001), worsening by up to 0.53 points on average. This was followed by the degree of hyperemia (p=0.025), which increased significantly after the use of glasses, and IOP (p=0.045), which showed a decrease of 1mmHg on average. Regarding the use of screens, the OSDI data once again shows the greatest difference, increasing 0.39 points on average (p=0.000). IOP (p=0.006) and meniscus height (p=0.017) also reached statistical significance with a clear decrease in them.
Conclusions
The findings in this study support the safety of the use of MR glasses in the adolescent population on a visual level, being completely comparable to the use of screens. In addition, they could represent a potential advantage over conventional screens, by reducing dry eye symptoms and increasing the tear meniscus. In an increasingly technological world, the use of MR glasses, by providing a farther focus distance and combining the natural and virtual environment, can translate into a blink rate closer to the usual one, resulting in fewer symptoms of dry eyes and a greater height of the tear meniscus, as demonstrated by our results.
