Often times we are asked if having clear vision means that our eyes are working well. In other words, is “20/20” all that’s needed to see well? The answer: NO!! It is important to see clearly (visual acuity) it is also important to move the eyes quickly and without fatigue (visual strength). Once those visual foundations are achieved what is most important is that you know where to look when.
The visual system is the most important sense for quality performance and there are many aspects to human vision (see below). All these components play a role in achieving excellence. Do you see everything you need to be at your best?
| Visual Component | Visual Question | System | Professional | What do I do to check my level of performance? |
|---|---|---|---|---|
| Visual Acuity | Can you see clearly? Do you have visual impairments? | Eye anatomy | Optometrist | Complete an eye exam annually |
| Visual Nutrition | How healthy are your eyes? For instance, can you see contrast in colors? | Eye biology | Ophthalmologist | Check the health of your eyes |
| Visual Strength | How quickly and accurately do you move your eyes? Do your eyes fatigue or can they maintain quick movements over long periods of time? | Eye musculature | OptometristVision TherapistOphthalmologist | Engage in visual exercise program |
| Visual Search | Where are you looking? How are you interpreting what you are seeing? | Visual system as it relates to the brain processing | OptometristVision Therapist | Functional vision exam |
| Visual Performance | How is your vision impacted by how you feel? Does stress impact vision? | Visual system as it relates to mental processes and changes in biochemistry | Primary Care MD Optometrist | Functional vision exam |
| Visual Peak Performance | All of the above | Biological, musculature, biochemical, mental | All of the above | All of the above |
