eSight: a proven low vision device for your patients with central vision loss¹

eSight enables patients with central vision loss to achieve up to 20/20 visual acuity.¹ It works by stimulating the synaptic nerve activity in the remaining photoreceptor function in the patient’s eyes to provide increased visual information to the brain. In doing so, eSight delivers life-changing results for thousands of people with macular degeneration, diabetic retinopathy, Stargardt disease and more.¹

eSight provides unprecedented improvement in a wide range of visual performance measures for patients with one of over 20 different eye conditions associated with central vision loss.¹ eSight is a class 1 medical device that is registered with the FDA and EUDAMED, and inspected by Health Canada.

Over 2/3 of eSight users reported sight enhancement when diagnosed with Macular Degeneration, Stargardt Disease, Diabetic Retinopathy, Aniridia, Uveitis, Optic Nerve Hypoplasia, Ocular Albinism, and Coloboma. ¹ *

eSight is clinically validated through a peer-reviewed multicenter trial

A multisite, prospective, single-arm study that involved six recruitment centers investigated the short- and medium-term effects of eSight. With a sample size of n=51, this study primarily demonstrated¹:

  • A seven-line gain in distance acuity
  • 100% mobility retention
  • 12 letter contrast improvement
  • Improvement in critical print size and reading acuity
  • Significant increase in facial recognition

Published in the Journal of Optometry and Vision Science. eQUEST, Identifier NCT02616900.

eSight Eyewear Significantly Improves Distance Acuity

Figure 1. Distance acuity equivalent of print size correctly read on the ETDRS chart at baseline without the device, at fitting with the device, and after 3 months of device use. Mean baseline acuity without device was 20/177 (mean logMAR, 0.95 [SD, 0.25]), which improved to 20/32 (mean, 0.20 [SD, 0.31]) with the device but stayed unchanged after 3 months of device use and training (mean, 0.19 [SD, 0.30]). *Statistically significant differences. ETDRS = Early Treatment Diabetic Retinopathy Study.

eSight Eyewear Significantly Improves Reading Acuity

Figure 2. Reading acuity equivalent of print size read on the MNREAD chart at baseline without the device, at fitting with the device, and after 3 months of device use. Mean baseline reading acuity without device was 20/159 (mean logMAR, 0.90 [SD, 0.34]), which improved to 20/43 (mean, 0.33 [SD, 0.39]) with the device but stayed unchanged after 3 months of device use and training (mean, 0.24 [SD, 0.36]). *Statistically significant differences.

Visual impairment and its impacts beyond sight

Approximately 2.2 billion people are visually impaired globally, of which 217 million have significant visual impairment, and 36 million are blind.4,5

Impaired visual function is associated with reduced cognitive function6 which can impact7:

  • Language
  • Memory
  • Attention
  • Visuospatial Ability

Vision impairment is correlated with unintentional injuries, loneliness, and diminished quality of life, and it poses a greater risk for developing mood disorders such as depression.8-11 In one study, up to 45.2% of adults with severe visual impairment reported moderate-to-severe depressive symptoms.12

As vision acuity declines, patients are willing to trade a significantly higher percentage of their remaining lifetime to regain vision.13

Specifically, 67% and 51% of patients in one study (n=72) were willing to trade remaining life years, and willing to risk chance of death, respectively, for perfect vision in both eyes.13 This was not limited to the legally blind, as patients with 20/60 to 20/100 visual acuity were willing to trade 43% of their remaining life years.11

Beautiful stories from real users

Gary Foster, diagnosed with Macular Degeneration, has been an eSight wearer since 2015. In the initial stages of his central vision loss, he lost his job working in Parks Canada and began withdrawing from his family.

Fortunately, his family noticed the change in him and brought him to try eSight as one of many people in a long line wanting to look through the device. When it was Gary’s turn, his wife asked him what he saw. He replied, “I see your face.” Then, when looking around, he found that, “I can see everybody’s face.” His wife started to cry.

“It was my first look at eSight, and the world.”– Gary Foster, on trying eSight for the first time

He has now returned to his favourite hobbies and regained independence with eSight. Watch how eSight helped Gary regain his confidence.

Tony Babb has always lived with Stargardt disease, though it really began to impact his life in his early 20s. Today, Tony’s visual acuity is 20/300.

“I could no longer see my mother’s face, and that bothered me.” – Tony Babb

At the time, Tony was worried that sight loss could affect the rest of his life in terms of getting a job, meeting someone, having children, and being independent. But Tony’s ambitious personality persevered, and he led a successful career in sales while selling jewellery on the side. As Tony says, “I realized I had to rely on myself.”

After 38 years, Tony Babb was able to see for the first time with eSight. He was able to see his girlfriend’s face for the first time, and also pulled up a photo of his mother to see her face clearly for the first time in years. Tony has been using eSight since 2018, and now takes his kids out for bike rides, goes to his daughter’s ballet recital, and watches movies with his children. He is no longer restricted from activities that make him feel like a good father.

Sandy-Lynn always had vision-related issues and was diagnosed with Ocular Atrophy in her late teenage years.

Sandy-Lynn’s husband scoured the internet for the perfect vision enhancing tool and discovered eSight. From the moment she tried on eSight, Sandy-Lynn knew it was the beginning of something great.

With her eSight, newfound confidence and unconditional support from her friends and family, Sandra competed in the Special Olympics Florida in the Equestrian Area Games. She ended up winning two gold medals.

“I’m not handicapped, I’m handicapable. We shouldn’t all have to do everything exactly the same way. It shouldn’t matter how you do it as long as you do it, that’s quality of life. And that’s what eSight has given me, quality of life.” – Sandra-Lynn Elledge

While serving in the United States Marine Corps Reserves, at age 27, Guillermo Lopez III was diagnosed with a genetic eye disease.

Guillermo began noticing problems with his depth and distance perception while he was driving in 2015. After realizing the severity of his situation, he sought medical attention which led to his diagnosis of Leber’s hereditary optic neuropathy (LHON). As a result, he was medically released from the Marine Corps. While the experience was incredibly difficult, in Guillermo’s words:

“When one door closes, another opens“

Though he went back to school to complete his bachelor’s degree in recreational therapy at Texas State University, his low vision made his experience rather difficult. In November of 2019, he first experienced the capabilities of eSight, and since then, he has taken control of his learning and feels more connected to his classmates and professors. Since graduating, he started his own business with his partner, Bob’s Containers, and also runs a fitness center for people with visual impairments.
