With the advancement of technology, mainly related to electronics and computing, the use of the internet and electronic games has become increasingly popular. Videogame is widely used by young people and the internet across all age groups and all socioeconomic strata.(44 Griffiths M. Video games and health. BMJ. 2005; 331(7509):122-3.) The use of close-up vision for long periods caused by the excessive use of cell phones, smartphones, computers and video games can generate a spasm of accommodation, not allowing relaxation of the ciliary muscle and consequently not undoing the reflex of accommodation completely. Over time, this can become chronic and cause a pseudomyopia or a "hypo" stimulation of farsightedness. In addition, spasm can trigger the onset of asthmatic symptoms such as headache, tearing, low visual distances, blurring of vision, blurred vision, and conjunctival hyperemia, which may interfere with the quality of life of users.(55 Milder B, Rubin ML.

As in this study, Agarwal et al.(1515 Agarwal S, Goel D, Sharma A. Evaluation of the Factors which Contribute to the Ocular Complaints in Computer Users. J Clin Diagn Res. 2013;7(2):331-5.) identified a difference in frequency and prevalence of asthenopic symptoms when associated with daily time spent in front of computers. It is believed that the use of near vision for prolonged periods may be related to spasms of accommodation, with relaxation of the ciliary muscle and consequent triggering of visual and extra-visual symptoms, such as blurred vision, low visual distant, burning, lacrimation ocular and headache.(55 Milder B, Rubin ML.

The lens system of the eyeball is essential for the formation of images, and the composition of their structures ensures the transparency necessary for the passage of light, essential for the formation of images.(1717 Guyton AC, Hall JE.
