Optometric Principles for -4.00D Contacts
- Contact Lens Effect: Contact lenses sit right on the cornea, requiring slightly higher accommodative effort at 35 cm than glasses of the same power.
- Phase 1 (+2.00D Add): Reduces net near load to -2.00D. Eliminates instant ciliary locking so you can work comfortably.
- Phase 2 (+1.00D Add): Increases net near load to -3.00D. Builds stamina over 4 weeks.
- Phase 3 (-4.00D Solo): Removes readers completely. Hold screen at 45–50 cm initially to reduce demand by ~0.50D naturally.
