To know if you need glasses, assess your eye grade. A visual acuity of 20/200 or worse suggests you need corrective lenses. If your prescription is -0.75 to -5.00, it indicates mild to moderate nearsightedness. Severe nearsightedness, with a higher prescription, means you will need glasses for all activities.
Nearsightedness occurs when distant objects appear blurry. This condition is common in children and adolescents. Farsightedness affects close-up vision, making tasks like reading difficult. Astigmatism causes distorted or blurred vision at all distances. Individuals with these conditions may need glasses to improve clarity.
Optometrists determine the eye grade during an eye exam. They assess visual acuity, which measures how well a person sees at various distances. A prescription includes numbers that indicate the lens power needed for correction. Those with a higher prescription strength generally have a greater need for corrective eyewear.
In summary, understanding what eye grade needs glasses helps individuals recognize their vision health. Proper management through corrective lenses can significantly enhance quality of life. Next, we will explore the importance of regular eye exams and how they contribute to long-term eye health.
