From the Guidelines
Visual acuity testing for sports physicals is typically required starting around age 5 or 6, as stated by expert opinion and guidelines from the American Academy of Pediatrics 1. The age requirement may vary by state, school district, and sports organization, but most comprehensive sports physical exams include vision screening for school-aged children. Annual testing is recommended throughout childhood and adolescence, as good vision is essential for sports performance and safety 1.
Importance of Visual Acuity Testing
The testing is crucial because visual impairments can affect depth perception, peripheral awareness, and reaction time, potentially increasing injury risk 1. Children may not realize they have vision problems, making routine screening necessary. The standard test involves reading a Snellen eye chart from a specific distance, with results typically recorded as a fraction (like 20/20).
Screening Recommendations
According to the American Academy of Pediatrics, vision screening should be performed at all well-child visits for children starting in the newborn period to 3 years, including ocular history, vision assessment, external inspection of the eyes and lids, ocular motility assessment, pupil examination, and red reflex examination 1. For children aged 3 to 5 years, the AAP recommends the aforementioned screening in addition to age-appropriate visual acuity measurement (using HOTV or tumbling E tests) and ophthalmoscopy 1.
Referral to Eye Care Specialist
If vision problems are detected during a sports physical, referral to an eye care specialist may be necessary before sports participation is cleared 1. Early detection and treatment of amblyopia and amblyogenic risk factors can improve visual acuity, and treatments include surgery for strabismus and cataracts, use of glasses, contact lenses, or refractive surgery treatments to correct refractive error, and visual training, patching, or atropine therapy of the nonamblyopic eye to treat amblyopia 1.
From the Research
Visual Acuity Requirements for Sports Physical
- The age at which visual acuity testing is required for sports physicals is not explicitly stated in the provided studies 2, 3, 4, 5, 6.
- However, the studies suggest that visual acuity testing is an important aspect of sports vision assessment, and it is typically performed as part of a comprehensive eye examination 2, 3.
- The American Academy of Optometry recommends that athletes undergo a comprehensive eye examination, which includes visual acuity testing, to ensure that they have the necessary visual skills to perform safely and effectively in their sport 3.
- The studies do not provide a specific age range for visual acuity testing, but they do suggest that it is important for athletes of all ages to undergo regular eye examinations to ensure that their visual skills are adequate for their sport 4, 5, 6.
Visual Acuity Testing Methods
- The most repeatable method of testing visual acuity is with logMAR charts, either the Bailey-Lovie chart or the Early Treatment Diabetic Retinopathy Study chart 2.
- The Pelli-Robson and the Mars are the most repeatable contrast sensitivity tests 2.
- Dynamic visual acuity testing, such as the Dynamic Visual Acuity Test (DVAT), can also be used to assess an athlete's visual performance 4, 5.
Importance of Visual Acuity Testing
- Visual acuity testing is important for ensuring that athletes have the necessary visual skills to perform safely and effectively in their sport 3, 6.
- The ability to identify athletes who may benefit from improved visual acuity or have sports-specific significant ocular findings is crucial for preventing injuries and improving performance 3.
- Comprehensive eye examinations, including visual acuity testing, can help identify athletes who may be at risk for eye injuries or have underlying eye conditions that could affect their performance 3, 4, 5, 6.
