Reservists and Corrective Lens Prescriptions
Reservists in the military may be required to provide updated corrective lens prescriptions from their civilian provider on a regular basis.
The specific frequency at which these updates are required can vary depending on the branch of the military and individual circumstances. However, it is generally recommended for reservists to provide updated prescriptions at least once a year.
This ensures that they have the most accurate prescription for their corrective lenses, which is important for maintaining optimal vision and fulfilling their duties effectively.
