What happens to a driver's license if their eyesight deteriorates significantly?

When a driver's eyesight deteriorates significantly, the driver is required to have their vision corrected to ensure safety while operating a vehicle. If a driver fails to meet the eyesight requirements set by the licensing authority, their license will typically be revoked unless they take the necessary steps to correct their vision, such as wearing glasses or contact lenses or undergoing medical treatment. This approach prioritizes road safety for all users by ensuring that drivers are fit to operate a vehicle safely. Maintaining adequate vision is crucial for tasks such as recognizing signs, perceiving distances, and responding to other road users, which are essential for safe driving practices.
