Verified step by step guidance

1. Understand that alcohol affects the central nervous system, including the visual system, which impacts how the eyes function while driving.
2. Recognize that one key effect of alcohol on the eyes is the reduction of peripheral vision, which means the ability to see objects outside the direct line of sight is impaired.
3. Know that this reduction in peripheral vision can make it harder for drivers to detect hazards coming from the sides, increasing the risk of accidents.
4. Be aware that alcohol does not improve the ability to focus on moving objects; in fact, it generally impairs visual tracking and focus.
5. Remember that alcohol also does not increase night vision or sensitivity to light; instead, it often causes blurred vision and slower eye movement responses.
