Digital display use has been accepted to be implicated as a contributing factor for dry eye disease (DED). Abnormal blinking during computer operation, including a reduced blink rate and an incomplete eyelid closure, increased palpebral fissure as consequence of high visualization angles, and meibomian gland dysfunction associated to long-term display use, are behind the increased prevalence of dry eye signs and symptoms found in digital display users. Previous research reveals significant reductions in tear volume and stability, alterations in tear film composition, including increased osmolarity, inflammatory cytokines, oxidative stress markers and reduced mucin secretion, eyelid abnormalities and ocular surface damage, encompassing corneal and conjunctival staining and bulbar redness, as a direct consequence of digital display use. In this regard, individual differences in the way that the various digital displays are typically set up and used may account for differences in their effects on induced dryness signs and symptoms. Furthermore, factors such as the use of contact lenses or inappropriate working environments, usually accompanying the use of displays, may significantly increase the prevalence and the severity of induced dry eye. Other factors, such as old age and female gender are also relevant in the appearance of associated alterations. Finally, clinicians should adopt a treatment strategy based on a multidirectional approach, with various treatments being applied in conjunction.

数字显示器的使用已被认为是干眼病（DED）的促成因素。在计算机操作过程中异常眨眼，包括眨眼频率降低和眼睑闭合不完全，由于高可视角度导致睑裂增加以及长期使用显示器而导致睑板腺功能障碍，是造成干眼症和症状增加的原因在数字显示用户中找到。先前的研究表明，泪液体积和稳定性显着降低，泪液膜成分发生改变，包括渗透压增加，炎性细胞因子，氧化应激标志物和粘蛋白分泌减少，眼睑异常和眼表损伤，包括角膜和结膜染色以及延髓红肿。数字显示使用的直接后果。在这方面，通常设置和使用各种数字显示器的方式上的个体差异可以解释其对引起的干燥迹象和症状的影响的差异。此外，诸如隐形眼镜的使用或不适当的工作环境等因素，通常伴随显示器的使用，可能会大大增加患干眼症的患病率和严重程度。其他因素，例如老年和女性，也与相关变化的外观有关。最后，临床医生应采用基于多方向方法的治疗策略，并结合应用各种治疗方法。此外，诸如隐形眼镜的使用或不适当的工作环境（通常伴随显示器的使用）等因素可能会显着增加诱发干眼症的患病率和严重程度。其他因素，例如老年和女性，也与相关变化的外观有关。最后，临床医生应采用基于多方向方法的治疗策略，并结合应用各种治疗方法。此外，诸如隐形眼镜的使用或不适当的工作环境（通常伴随显示器的使用）等因素可能会显着增加诱发干眼症的患病率和严重程度。其他因素，例如老年和女性，也与相关变化的外观有关。最后，临床医生应采用基于多方向方法的治疗策略，并结合应用各种治疗方法。
