Convergence insufficiency is becoming more and more prevalent, and the symptoms more devastating, as we spend more and more time in front of screens. Symptoms often include headaches, fatigue, dizziness, blurry vision, suppression, etc. Without proper treatment, the eyes are forced to manually converge, intensifying these symptoms. Although the eyes might be the problem, Chadwick’s Converge lenses might be the solution.
What is Converge?
Any progressive lens design is designed with a sweet spot that incorporates the fitting height of the lens and inset. This sweet spot is typically placed horizontally to accommodate a normal convergence for a near object and does not account for any of the patient’s potential vergence issues. The Converge lens design factors in a patient’s convergence insufficiency and incorporates prism to help guide the patient’s eye comfortably down the corridor of the lens.
How Does Converge Help?
Our Converge lenses allow providers to add as much prism as needed. The gentlest version of the lens has 0.87 diopters of accommodative relief, and 0.37 diopters of base in prism at nearby. If needed, more prism is available at higher add powers. Chadwick offers a standardized amount of base in prism, along with customization options for practitioners wanting more design flexibility.
