Introduction
Excessive television viewing or watching TV from too close a distance increases the risk of myopia in children. For children under the age of two, electronic devices—including televisions—are generally discouraged. After age two, screen time should be strictly limited: no more than 20 minutes per session and no more than 1 hour total per day, due to the adverse effects of prolonged electronic device use.
In recent years, myopia has increasingly affected younger populations. Myopia causes significant inconvenience for patients and may impact their outward appearance. So, how long can children watch television before developing myopia?
How Long Can Children Watch Television Before Developing Myopia?
Excessive television viewing or watching TV from too close a distance increases children’s risk of developing myopia. For children under two years of age, electronic devices—including televisions—are generally discouraged. After age two, screen time should be strictly limited: no more than 20 minutes per session and no more than one cumulative hour per day. Prolonged use of electronic devices—including television—has been associated with an increased risk of myopia in children and may contribute to its earlier onset.
In daily life, several measures can help prevent myopia development. Ensure children maintain a balanced diet rich in nutrients essential for healthy eye development. Strictly limit screen time—including television—and especially avoid prolonged, close-range viewing. Guarantee adequate sleep to allow the eyes sufficient rest, and encourage regular outdoor activities, which have been shown to help reduce the incidence of myopia.
In everyday life, proper posture and healthy visual habits should be consistently reinforced to prevent worsening of astigmatism. We hope this information is helpful to you.
