Impact of virtual reality headset use on eye blinking and lipid layer thickness

open access: yesJournal Francais D'Ophtalmologie, 2021
Blinking plays an important role in protecting the eyes, and the use of computers has been associated with a reduction in the blink rate. The goal of this study was to evaluate the effect of a virtual reality headset on blinking and lipid layer thickness and to compare these data to those associated with a conventional desktop monitor.Two experiments ...

Characterization of the thickness of the tear film lipid layer using high resolution microscopy [PDF]

open access: yesOcular Surface, 2019
Interferometry is an optical technique that have been used to quantify the lipid layer of the precorneal tear film, and to investigate the relationship between lipid layer thickness and tear film evaporation. However, the relationship between lipid layer thickness and the rate of evaporation is far from consistent.

Tear Film Lipid Layer Thickness as a Function of Blinking

Cornea, 1994
Alterations in the tear film lipid layer as a function of blinking were investigated using a custom-designed specular reflection monitoring system. The tear film lipid layer of 104 subjects under conditions of normal ("baseline") blinking and "forceful" blinking was quantitated on the basis of specific interference colors. Deliberate, forceful blinking

The Relationship Between Dry Eye Symptoms and Lipid Layer Thickness

Cornea, 2009
(1) To investigate the relationship between dry eye symptoms and lipid layer thickness (LLT) in patients presenting for routine eye examination and (2) to consider the practicality of interferometry in a clinical practice.Patients presenting consecutively for routine eye examinations were recruited (n = 137, age range = 18-60 years, mean = 41.7 +/- 15 ...

A preliminary investigation into the relationship between ocular surface temperature and lipid layer thickness

Contact Lens and Anterior Eye, 2009
The aim of this study was to establish the relationship between OST, tear film stability as assessed by NIBUT and subjective evaluation of the lipid layer thickness in a young, asymptomatic, sample group (N=29). Non-invasive tear break-up time (NIBUT) and tear lipid layer structure were evaluated through a slit-lamp mounted Tearscope Plus.

Comparison of the Efficacy of Two Lipid Emulsion Eyedrops in Increasing Tear Film Lipid Layer Thickness

Eye & Contact Lens: Science & Clinical Practice, 2007
The lipid layer of the tear film is critical to maintaining the thickness of the multilayered tear film. This study was designed to determine whether a single drop of Refresh Dry Eye Therapy or Soothe, both lipid emulsion eyedrops, significantly increased the lipid layer thickness (LLT) of patients with self-reported dry eyes and thin lipid layers ...

Determination of Lipid Layer Thickness with Broadband Diffuse Optical Spectroscopy

Biomedical Optics, 2006
Broadband Diffuse Optical Spectroscopy (DOS) measurements performed on the forearm of ten subjects with varying lipid layer thicknesses are correlated with skin fold calipers values to show that DOS can be used independently to measure lipid layer thickness.
