The positive impact of glasses is significant. Eyeglasses can improve vision, which can lead to increased safety and productivity in various settings, such as driving or working. They can also boost confidence and self-esteem in people who may feel self-conscious about their vision. Additionally, eyeglasses can protect the eyes from harmful UV rays, which can prevent eye diseases such as cataracts and macular degeneration. Overall, eyeglasses can improve quality of life and contribute to better eye health.
