The Aperture Rule is a specialized vision therapy tool designed to improve vergence skills, depth perception, and eye coordination. Primarily used to train convergence and divergence, it also provides indirect benefits for accommodative flexibility, making it a valuable tool for individuals with binocular vision disorders, convergence insufficiency, and visual fatigue.

Key Benefits:

Vergence Training: Strengthens convergence (single aperture) and divergence (double aperture) to enhance binocular vision efficiency.
Depth Perception Enhancement: Helps improve stereopsis by challenging the eyes to fuse images correctly.
Indirect Accommodative Benefits: Since accommodation and vergence are neurologically linked, training vergence can help improve accommodative control and stability.
Reduces Visual Fatigue: Helps alleviate symptoms of digital eye strain and near work discomfort by improving eye coordination.
Adjustable Difficulty: Suitable for different skill levels, making it ideal for clinical therapy and home-based vision training.

Who Can Benefit?

• Individuals with convergence or divergence insufficiency
• Patients experiencing eye strain from prolonged near work
• Athletes looking to enhance depth perception and eye teaming
• Children and adults undergoing vision therapy for binocular vision disorders

While the Aperture Rule is primarily used for vergence therapy, its training effects can also support accommodation by reinforcing the eye’s ability to maintain clear, stable focus. For a comprehensive approach, it can be combined with direct accommodative exercises like lens flippers.
