In what scenario can a driver's license remain valid despite eyesight deterioration?

A driver's license can remain valid if a driver's eyesight deterioration is corrected with the use of glasses. Many jurisdictions allow individuals to wear corrective lenses, such as glasses or contact lenses, to meet the vision requirements necessary for maintaining a valid driver's license. When a person’s vision is improved to meet the legal standards for driving through the use of these aids, they are considered competent to operate a vehicle safely.

It’s important to note that while temporary vision aids might assist in certain situations, relying exclusively on these aids without meeting specific requirements would not suffice for maintaining a valid license. Similarly, the discretion of the examiner doesn’t provide a guaranteed solution since they are bound by established regulations that adhere to clear vision standards. A scenario where a license cannot remain valid indicates that there are certain thresholds for vision that must be met, and deterioration beyond these thresholds would lead to invalidation.
