SureSight Vision Screener

Refractive disorders are very common in children. Disorders like farsightedness, shortsightedness, and astigmatic affect millions of children globally. Unfortunately, in most children, vision disorders often go undetected for many years. This often leads to poor academic performance and more important, the child is unable to participate in social and sporting activities. Further, if a condition like a lazy eye (amblyopia) is left untreated, it leads to permanent blindness. This leads to lack of job opportunities, difficulty driving, and a poor quality of life. Even when teachers note difficulties in vision in children, they are often powerless to do anything about it.

For a long time, one major obstacle in eye testing was the lack of a suitable machine. Most of the traditional eye screening machines are large, cumbersome, lack portability and often induce panic/fear in children.

Now, finally, there is a small portable machine that can help assess refractive disorders in children. The SureSight Vision Screener was developed to screen for vision problems anywhere and in any age group. It is the most accurate vision-screening device on the market. Within seconds, the machine can diagnose any type of refractive disorder. There are countless data indicating that when refractive eye disorders are promptly diagnosed and treated, not only do people do well in academics but also the quality of life is vastly improved.

What is SureSight Vision Screener?

SureSight Vision Screener has been developed using Welch Allyn’s latest proprietary technology to screen for eye diseases with speed accuracy and rapidly. It overcomes the problems associated with eye chart screening or a visit to the optician’s clinic. This portable machine that runs on a battery can be used in any environment and can screen for refractive eye disorders in people of all ages including infants. Within seconds, the SureSight device automatically screens for common refractive disorders like nearsightedness, farsightedness, and astigmatism. The SureSight Vision Screener is a hand-held device and can be used in the clinic, in schools, the home, or any other place.

In what age group can the SureSight Vision Screener be used?

The SureSight Vision Screener can be used to screen vision in babies, children, and adults. In fact, the device is so versatile it can even be used to screen people while they are wearing contact lenses or eyeglasses. Irrespective of the person’s disability, age, race, gender, occupation, or lifestyle, the SureSight can be used to check vision. The SureSight has been designed in such a way that it makes eye screening easy, entertaining and fun.

What visual problems can the SureSight screen?
