Introduction
Under normal circumstances, a visual acuity of 4.5 refers to a vision test result of 4.5, which may correspond to a myopia level between 300 and 450 degrees. Patients with myopia should pay attention to their eye usage habits and include foods rich in vitamin C in their diet, such as fresh vegetables and fruits. If any discomfort occurs, it is recommended to seek medical treatment promptly.
Visual acuity of 4.5 typically corresponds to a myopia level between 300 and 450 degrees. If discomfort occurs, it is recommended to seek medical attention promptly and receive standardized treatment under a doctor's guidance, which can aid in recovery.
Visual acuity measurements usually refer to uncorrected vision tested using an eye chart. On a logarithmic visual acuity chart, values range from 4.0 to 5.2, with normal human vision being 5.0. A person's degree of refractive error is generally determined through an optometric examination. Since there is no direct conversion between visual acuity test results and refractive error measurements, the exact degree of myopia corresponding to a visual acuity of 4.5 cannot be precisely determined, but it generally falls within the range of 300 to 450 degrees.
Individuals with myopia should pay close attention to their eye usage habits, limit screen time on electronic devices, and avoid prolonged eye strain. After using the eyes for a period of time, it's important to take appropriate breaks—such as closing the eyes to rest or gently massaging the eye area—to improve local blood circulation and help relieve discomfort.
Diet-wise, it's important to consume foods rich in vitamin C, such as fresh vegetables and fruits. In daily life, one should develop healthy lifestyle habits, ensure sufficient sleep, avoid staying up late, and maintain a positive mood while minimizing anxiety and irritability, all of which contribute to overall health.
