Myopia of 500 degrees is moderate myopia, which is not as severe as high myopia, but patients should usually take reasonable measures to prevent the number of degrees from rising. Moderate myopia is 300-600 degrees and 500 degrees is a moderate degree of myopia. Without glasses, patients can only see larger objects in the near distance without distinguishing details, thus affecting their quality of life and safety in daily life, which requires some attention. For minors with 500 degrees of myopia, frames and keratoplasty lenses are preferred, while correcting eye habits to prevent further aggravation of myopia due to poor sitting posture and excessive eye use, which can lead to serious complications such as retinopathy and fundus damage. Adults can also choose contact lenses or surgery to correct the problem. Although myopia of 500 degrees is not particularly serious, it can be aggravated if it continues to progress. Therefore, patients should pay attention to reasonable eye use in daily life, avoid using electronic products for a long time, look farther away, and eat more foods rich in vitamin A or vitamin E, etc.
