Ophthalmologist Yelena Polonina stated that the deterioration of children's eyesight is not limited to the impact of smartphones and electronic devices, but also includes a number of other factors, such as sunlight and diet.

She says: "Research results indicate that the cause of myopia is not visual strain itself, but rather the lack of time that children who study a lot spend outdoors during the day."
According to her, fresh air and sunlight can affect a child's eyesight because they stimulate dopamine production in the retina. This neurotransmitter slows the excessive growth of the eyeball, which can lead to nearsightedness. If a student spends most of their day indoors and rarely goes outside, this protective mechanism becomes ineffective.
Lighting is equally important. Insufficient or unsuitable lighting causes greater eye strain. Right-handed users are advised to place their desk lamp on the left side, while left-handed users should place it on the right. However, if the room is dark and the only light source is a desk lamp, the contrast will be stark, quickly tiring the eyes and causing constant spasms in the adaptive muscles.
A child may experience vision problems due to genetics, as the risk of developing myopia (nearsightedness) is higher in children whose parents have the condition.
In addition, malnutrition can negatively affect vision. A deficiency in vitamins A, C, and E, zinc, lutein, and omega-3 fatty acids in the diet affects the health of the retina and eye tissues.
To compensate for the deficiency, the doctor advises adding fish, eggs, carrots, broccoli, red peppers, spinach, blueberries, citrus fruits, and nuts to the child's diet.
