A 600-degree eye generally refers to a myopia of 600 degrees, which is a high degree of myopia and requires regular funduscopic examinations along with vision correction, as well as attention to reasonable eye use to prevent further growth. High myopia is mostly accompanied by the growth of the eye axis, which is irreversible and requires correction of vision through prescription glasses and surgery. High myopia has a higher risk than the general population of developing fundus lesions such as retinal lattice-like degeneration and retinal detachment, so regular fundus examinations are recommended for early intervention when problems arise. With myopia of 600 degrees, patients need not worry too much if they pay attention to reasonable eye use, avoid strenuous activities and have regular funduscopic examinations.
