EVOQ Brings Twilight Dark Adaptometer and New Night Vision Monograph to Academy 2026 Anaheim

For EVOQ, the device puts a measurement around a common but difficult-to-quantify concern: a patient’s trouble seeing at night. The company demonstrated its Twilight Dark Adaptometer and introduced a new monograph, The Unseen Epidemic. Why Night Vision Loss Is the Canary in the Coal Mine of Retinal Health.

The Twilight device measures dark adaptation, or how the eye recovers its sensitivity after exposure to light. EVOQ says that measurement can help clinicians turn a patient’s description of night vision loss into data they can follow over time. The portable system is designed for primary eye care and sends test results to the company’s SightGard cloud platform for analysis and longitudinal review.

For an optometrist, the distinction is between what a patient experiences and what a conventional structural image shows. EVOQ argues that functional changes can emerge before damage is visible on imaging. Its approach is intended to add a functional measurement to the clinical picture, not replace a comprehensive eye examination or structural testing.

The company says Twilight also includes a medical necessity survey to help practices document the reason for testing. That feature is part of EVOQ’s effort to make dark adaptation testing practical in a primary care setting, where time, staffing and reimbursement questions can affect adoption.

At Booth 566, EVOQ offered Twilight demonstrations and the opportunity for visitors to view their own dark adaptation curves. The company invited optometrists and ophthalmologists, as well as researchers interested in dark adaptation and distributors serving eye care practices. Signed copies of the new monograph were also part of the presentation.

Kasia Hein-Peters, MD, EVOQ’s CEO, said: “We want to raise awareness of nyctalopia as a growing and important clinical problem and emphasize the need for dark adaptation testing in all primary eye care clinics.”
