Frequently Asked Questions

How is iScreen Vision different than other eye tests?

iScreen Vision is specifically designed for pediatric vision screening and can be especially useful for children who are preverbal or developmentally challenged. Many eye tests for children simply test visual acuity, but iScreen Vision offers a thorough screening test for eye abnormalities that are risk factors for amblyopia, also known as “lazy eye.”

How comprehensive is iScreen Vision photoscreening?

iScreen Vision’s photoscreening technology screens for major amblyopia risk factors that can lead to permanent vision loss or blindness if not detected early. iScreen Vision also screens for refractive error and other serious eye problems, including: anisometropia, astigmatism, cataract, coloboma, hyperopia, myopia, ptosis and strabismus.

Why make iScreen Vision photoscreening a part of my pediatric practice?

Studies show that, on average, one in every four of your pediatric patients suffers from a vision problem — but only 36 percent of children aged six or younger have had their vision tested. With iScreen Vision, you can prevent permanent vision loss by detecting risk factors when treatment is most effective.

Does iScreen Vision require special training?

No. If you can operate a point-and-shoot digital camera, you can operate the iScreen Vision Screener 3000. iScreen Vision offers both on-site and remote training to help customers easily incorporate iScreen Vision into their daily practice.
