Nowadays, many teenagers suffer from different degrees of myopia. For myopia patients, bungee jumping is not recommended as an extreme sport. Because the axial length of myopia patients is elongated, the vitreous body in the eye is liquefied, and the supporting effect on the retina is weakened. In the weightless state of bungee jumping, it may cause retinal detachment and lead to blindness. Especially for patients with high myopia whose myopia degree exceeds 600 degrees, the retina is more likely to fall off when the body speed changes suddenly.

When bungee jumping, the sympathetic nerve of human body is excited, and adrenaline and other substances are secreted in large quantities, which leads to the acceleration of heartbeat and the increase of blood pressure. Therefore, people with organic heart disease, hypertension, cardiovascular and cerebrovascular diseases should not challenge bungee jumping.
