Использование мобильных телефонов широко распространено в цифровую эпоху, что потенциально влияет на здоровье глаз. Цель исследования — оценка воздействия различных длин волн экрана мобильного телефона, а также индуцированной миопической и гиперметропической дефокусировки на состояние глаз. Материал и методы. Предварительное и послетестовое квазиэкспериментальное исследование включало 50 студентов-эмметропов в возрасте 20,68 ± 0,98 года без нарушений со стороны глаз или общего состояния здоровья и без значительной рефракционной ошибки по данным ретиноскопии в Пакистанском институте офтальмологии, глазной больнице Al-Shifa Trust (Равалпинди) с использованием невероятностной оценочной выборки. Осевая длина глаза измерялась с помощью IOL Master 800 после тщательного офтальмологического обследования. Источником воздействия на орган зрения фиолетового, синего, желтого, белого, зеленого и красного света было мобильное приложение Android «Flash Screen». Миопическую дефокусировку вызывали с помощью линз +3,00 D, а гиперметропическую — с помощью линз -3,00 D. Данные были проанализированы с помощью пакета Jaffery Amazing Statistical Package (JASP). Результаты. Исходная длина передне-задней оси глаза (ПЗО), составлявшая 23,235 ± 0,657 мм, существенно менялась в ответ на экспозицию всех перечисленных цветов, как с наведением миопического и гиперметропического дефокуса, так и без него. Достоверное укорочение ПЗО отмечено под действием фиолетового и в меньшей степени голубого цвета (p < 0,001). Желтый цвет незначительно изменял ПЗО. Длинноволновый (зеленый и красный) свет вызывал удлинение ПЗО (p < 0,001), причем гиперметропический дефокус усиливал этот эффект. Заключение. У эмметропов длина ПЗО изменяется в ответ на воздействие света разной длины волны как результат продольной хроматической аберрации - спектрального дефокуса, который доминирует над оптическим дефокусом.

Purpose. Mobile phone usage is widespread in the digital age, potentially affecting eye health. This study aims to evaluate the effect of mobile screen exposure to different wavelengths, along with induced myopic and hyperopic defocus. Material and methods. A pre- and post-test quasi-experimental research of 50 emmetropic undergraduate students with a mean age of 20.68 ± 0.98 years were performed at the Pakistan Institute of Ophthalmology, Al-Shifa Trust Eye Hospital, Rawalpindi, Punjab, Pakistan, utilizing non-probability judgmental sampling. Those without ocular or general health issues and no significant refractive error on retinoscopy were included. Axial length (AL) was measured using the IOL Master 800 after thorough eye and visual examinations. An Android mobile application “Flash Screen” exposed participants to violet, blue, yellow, white, green, and red light. Myopic defocus was induced using +3.00 D lenses and hyperopic defocus with -3.00 D lenses. Jaffery Amazing Statistical Package (JASP) analyzed data. Results. Baseline axial length (AL BL) was 23.235 ± 0.657 mm. AL changed significantly after exposure to violet, blue, yellow, white, green, and red light with and without induced myopic (MD) and hyperopic (HD) defocus. Significant AL decreases (p < 0.001) were seen under violet and blue light settings, with an effect size (ES) at 1.000. Under hyperopic defocus, green and red light revealed considerable alterations (p < 0.001), with significant negative impacts. Yellow light barely changed AL. Conclusion. Emmetropes exhibit AL changes to different wavelength as per longitudinal chromatic aberrations, and dominate optical defocus effect.
