T or F: A PIC may use prescription glasses to keep the UA within line-of-sight.

• A. It is not allowed to use prescription glasses
• B. It is allowed to use prescription glasses
• C. It depends on the environment
• D. It requires a waiver

Answer: (B)

Maintaining visual line of sight is the key requirement, and corrective lenses are allowed to help you meet that standard. If you need prescription glasses to clearly see the drone and stay within the line of sight, you may wear them while operating. The rule focuses on whether you can see the UA clearly, not on whether you’re wearing glasses, so environment or waivers aren’t the deciding factors here. If your vision with glasses meets the necessary acuity, using them is appropriate; if not, you shouldn’t operate until you can meet the requirement.
