What adaptation schedule can we formulate for a new GP lens wearer?

• A. 2+2 schedule; 2 hours day 1, 4 hours day 2
• B. 8 hours daily from day 1
• C. 4+2 schedule; 4 hours day 1, 6 hours day 2, 8 hours day 3, etc
• D. 1 hour increments

Answer: (C)

The idea is to introduce a new GP lens wearer to use time gradually, so the eye can adapt to a rigid, highly oxygen-permeable lens without irritation or excessive strain. A paced buildup of wear time helps prevent corneal swelling and discomfort and lets the clinician monitor comfort, lens movement, and tear quality as tolerance improves. The 4+2 schedule does this most effectively: start with 4 hours of wear on day one, then extend to 6 hours on day two, then 8 hours on day three, and continue increasing in similar steps until full-day wear is reached. This approach balances the eye’s needs for oxygen and tear exchange with the patient’s comfort, giving a clear, manageable path to full-time wear.

The other options don’t fit as well because they either start with too little exposure to gauge tolerance, or push to full or near-full wear too quickly, which can provoke discomfort or adverse responses, or spread increments in a way that’s impractical or less protective of ocular adaptation.
