Smartphones and vision

Many people spend too much time using their smartphones. Contrast, small screen size, resolution, image repetition frequency and screen reflection will cause characteristic ocular symptoms. The objective of this study is to describe the ophthalmological symptoms in persons who spend a large number of hours using electronic devices. For this purpose, a search was conducted in the Pubmed and MED line database to find the appropriate articles. The most frequent ocular manifestation after prolonged use of smartphones without care for eye hygiene were ocular complaints, such as tiredness, eye irritation, blurred vision and transient, but marked elevated intraocular pressure. Early and adequate recognition of ophthalmic symptoms that may be associated with the using smartphones for many hours and the implementation of appropriate management can protect against the occurrence of late complications in the form of permanent eye damage.
