From the Guidelines
For most sports physicals, 20/40 vision is generally acceptable to pass, but this can vary depending on the specific sport and the requirements of the organization conducting the physical. Many school and recreational sports programs consider 20/40 vision adequate for participation, especially if this is your uncorrected vision and you wear corrective lenses during play 1. However, some sports with higher visual demands or safety concerns (like motor sports or archery) might require better visual acuity. According to the vision rehabilitation preferred practice pattern, children are considered to have low vision if their visual acuity cannot be corrected to 20/40 at both near and at distance, or have significant scotoma, visual field constriction, hemianopia, nyctalopia, color vision impairment, or other conditions that interfere with vision 1. If your vision is 20/40, you should bring any prescribed glasses or contacts to your physical exam. The examining physician will ultimately determine if your vision meets the requirements for your particular sport. Vision standards exist because adequate visual acuity is important for tracking moving objects, spatial awareness, and preventing injuries during athletic activities. Some key points to consider include:
- The specific sport and organization requirements
- The use of corrective lenses during play
- The potential need for better visual acuity in certain sports
- The importance of discussing vision concerns with the healthcare provider conducting the physical. It's also worth noting that the definition of low vision and visual impairment can vary, but in general, 20/40 vision is not considered to be a significant impairment 1.
From the Research
Visual Acuity Requirements for Sports Physical
- The required visual acuity for a sports physical can vary depending on the specific sport and organization, but a common standard is 20/40 in both eyes [@\5@].
- However, it's essential to note that visual acuity is just one aspect of visual function, and other factors like contrast sensitivity and visual field may also be important [@\4@].
Relationship Between Visual Acuity and Sports Performance
- Research suggests that visual acuity is not the only factor that determines an individual's ability to perform in sports, and other visual skills like contrast sensitivity and depth perception may be more critical [@\4@].
- A study on the relationship between visual acuity and contrast sensitivity found that even when visual acuity is relatively normal, individuals with certain eye diseases may still have significant deficits in contrast sensitivity [@\4@].
Contact Lenses and Visual Acuity
- Contact lenses can improve visual acuity in individuals with refractive errors, and some studies have found that contact lenses can provide better visual acuity than glasses in certain situations [@\1@, @\2@].
- However, the type of contact lens and the individual's specific visual needs can affect the level of visual acuity achieved [@\2@, @\3@].

Visual Acuity Measurements
- Visual acuity is typically measured using a standard eye chart, and the results are expressed as a fraction (e.g., 20/40) [@\5@].
- However, visual acuity measurements can be affected by various factors, including lighting conditions and the type of chart used [@\5@].
