Construction sites often have tower cranes to aid work crews in putting the structure together. The cranes are controlled by a single operator inside a booth at the crux of the crane. The problem, however, is that the operator may need help for vision problems while trying to handle everything, even when there’s a supervisor guiding the placement of the crane’s load.

High-Stakes Construction

Project managers and crane crews in Indianapolis will be familiar with the importance of cranes and the risks in operating one. The recent construction season in the city saw the Department of Public Works mobilizing its fleet of cranes, backhoes, and other construction equipment, to effect around $126 million worth of repair work and new projects. If you’re a crane operator with troubled eyesight in the pursuit of your duties, seek help at a local eye care practice, such as Moody Eyes.


The Occupational Safety and Health Administration mandates that crane operators undergo training at a certified heavy equipment training center. On top of this, the operator must also have exceptional hand/eye coordination, ability to focus intently, and clear vision, including peripheral vision. This is on top of blind-spot cameras installed at the booth to help the operator maneuver the machine around blind spots.


With the visual issues involved in operating a crane, an eye exam is a must for the operator. In fact, this could be a requirement for equipment qualification purposes. There are a number of factors to be accounted for:

  • Vision – clear vision is usually defined as 20/20 as stated in a Snellen chart. The OSHA accepts up to 20/50 vision in both eyes.
  • Depth Perception – The eye exam will also gauge depth perception. This is critical in judging the distance of the load carried by the crane. Poor depth perception carries a higher risk of accidentally misplacing the carried load or striking a section of the site.
  • Light sensitivity – Crane operators tend to work at dizzying heights and when the work happens early or late in the day, the angle of the sun can seriously disrupt the crane operator’s concentration.

A crane operator, or any other employee tasked with something as critical, cannot overlook the importance of having clear vision. In many cases, prescription lenses can provide the answer to vision problems. Eye care practitioners like those at Moody Eyes can help locals make sure their visual acuity is where it should be for the job they have to do.
