Can You Put the Peli Lens™ In Both Eyes?

It's a common and understandable question: if a patient's hemianopia affects both eyes, why wouldn't you prescribe the Peli lens for both eyes? This video dives into the nuanced answer, explaining the critical difference between monocular and binocular visual fields. In this video, you'll learn: 0:00:23 | Understanding Hemianopia: How this condition results in half-field vision loss in both eyes, and the Peli lens's goal to expand the visual field to the blind side. 0:00:58 | Monocular vs. Binocular Visual Field: Why individual eye tests don't always capture the full picture of what a patient sees with both eyes working together. 0:01:27 | The Impact of a Single Peli Lens: How fitting a Peli lens on one eye pulls information from the blind side into the seeing side, creating a beneficial expansion while causing a scotoma (blind spot) in that individual eye's field. 0:02:10 | The Consequence of Dual Peli Lenses: Why placing a Peli lens on both eyes results in creating blind spots (scotomas) in the same location in both eyes, ultimately diminishing the overall binocular visual field. 0:02:35 | Maximizing Binocular Field with a Single Lens: Why fitting a Peli lens on just one eye allows the "seeing" eye to provide central vision while the Peli-equipped eye expands the peripheral field, leading to a larger effective binocular visual field.
