Television is more harmful to the eyes than projectors, but both can damage the patient’s eyes if the patient is not careful about the time and distance of use.
Projectors generally project light onto a curtain or wall to present an image, the eyes look at the diffuse reflection of light, compared to television, projector images are larger, the patient is farther away from the image, so the patient is less likely to experience visual fatigue and myopia progression.
However, if we do not pay attention to the distance and time when using the laser projector, watching the projector for a long time and in close proximity can also damage our eyes, leading to visual fatigue, and can also lead to the development of myopia. Therefore, we should pay attention to avoid excessive eye use, participate in outdoor activities appropriately, and stay away from electronic products.
It is recommended that patients with eye discomfort should consult a doctor in a timely manner to assess their condition and follow the doctor’s instructions for treatment.
