📋 Clinical Recommendations
• Excellent visual acuity - maintain regular eye exams
• Eye exam every 1-2 years
Next Exam: Every 1-2 years
🌟 Lifestyle for Eye Health
• Wear UV-protective sunglasses outdoors (blocks UVA/UVB)
• Follow 20-20-20 rule: every 20 min, look 20 ft away for 20 sec
• Ensure adequate lighting when reading
• Position screens at arm's length, slightly below eye level
🥗 Nutrition for Eye Health
• Eat leafy greens (spinach, kale) - rich in lutein/zeaxanthin
• Include omega-3 fatty acids (fish, flaxseed)
• Consume colorful vegetables (carrots, bell peppers)
• Stay hydrated for tear film health
Important Limitations
- • Visual acuity is one component of vision - does not assess peripheral vision, color vision, or contrast sensitivity
- • Results depend on proper testing conditions (lighting, distance, chart quality)
- • Self-reported near vision may not match formal testing
- • Does not diagnose specific eye conditions - comprehensive exam needed

Understanding Visual Acuity
Visual acuity measures the eye's ability to resolve fine detail at a specific distance. The Snellen fraction (e.g., 20/20) is the most common notation in the United States. The numerator (20) represents the testing distance in feet, while the denominator represents the distance at which a person with normal vision can read the same line.

Driving Vision Requirements
| License Type | Visual Acuity Requirement | Notes |
| Standard (most US states) | 20/40 in better eye | With or without correction |
| Commercial (CDL) | 20/40 in each eye | Also requires visual field test |
| FAA Pilot (1st class) | 20/20 in each eye | Distance; near 20/40 |
| FAA Pilot (3rd class) | 20/40 in each eye | With or without correction |
Vision Measurement Systems
Snellen (US)
20/20 = Normal vision at 20 feet
Most common in clinical practice (US)
LogMAR
0.0 = 20/20, -0.3 = 20/10
Research standard, linear scale
Decimal (EU)
1.0 = 20/20, 0.5 = 20/40
