Cataract & Driving: What You Need to Know for Safety

Driving requires clear vision, quick reflexes, and the ability to process information efficiently. However, cataracts, a common age-related eye condition, can significantly impact these abilities, making driving unsafe. If you or a loved one is experiencing vision problems while driving, understanding how cataracts affect driving and what solutions are available can help you make informed decisions for safer roads.
How do cataracts affect driving?

Cataracts develop when the eye’s natural lens becomes cloudy, leading to a gradual decline in vision. Here’s how cataracts can impact your ability to drive safely:
- Blurry vision: Objects, road signs, and pedestrians may appear hazy or out of focus, making it difficult to navigate safely.
- Glare sensitivity: Cataracts can increase sensitivity to bright lights, making night driving especially challenging due to oncoming headlights and streetlights.
- Poor night vision: Many cataract patients struggle with dim or low-light conditions, making night driving risky.
- Reduced contrast sensitivity: It becomes harder to differentiate between objects, such as pedestrians wearing dark clothing or subtle changes in road texture.
- Double vision: Some individuals experience double vision in one eye, which can lead to misjudgment of distances and road hazards.
- Frequent prescription changes: If you find yourself needing frequent changes in your eyeglasses prescription, cataracts could be the cause.
Recognizing the warning signs
If you experience any of the following while driving, it may be time to consult an eye specialist:
- Difficulty reading road signs or recognizing traffic signals.
- Trouble seeing at night or needing extra light to drive safely.
- Feeling overwhelmed in bright sunlight or struggling with headlight glare.
- Increased near-misses or difficulty judging distances.
- Failing a vision test required for driving license renewal.
- Sudden reduction in peripheral vision, leading to difficulty detecting vehicles and pedestrians.
When to stop driving?
Driving with cataracts can be dangerous not only for you but also for other road users. If your vision significantly affects your driving, you may need to stop driving temporarily or permanently until the issue is resolved. Here’s when you should consider stopping:
- If you fail a driving vision test.
- If your eye doctor advises against driving.
- If you feel unsafe or hesitant while driving.
- If family members or friends express concerns about your driving ability.
- If night driving becomes increasingly difficult due to glare and halos around lights.
The visual standards for driving
Different countries have specific visual acuity and field of vision standards for driving. In India, a minimum visual acuity of 6/12 (with or without corrective lenses) is generally required to hold a driving license. If cataracts impair your vision beyond this standard, you may be deemed unfit to drive.
In addition to visual acuity, depth perception and glare recovery are also important factors. A decline in these abilities due to cataracts can significantly increase the risk of accidents. Regular vision checkups are essential to ensure that your eyesight meets the legal driving standards.
Tests you can take
If you suspect cataracts are affecting your driving ability, consider taking the following tests:
- Visual acuity test: Measures how clearly you can see at different distances.
- Contrast sensitivity test: Assesses your ability to distinguish between objects with similar shades.
- Glare sensitivity test: Determines how well you can see in bright or low-light conditions.
- Peripheral vision test: Ensures you have a wide enough field of vision to detect road hazards.
- Driving simulation test: Some advanced eye clinics offer simulation tests to assess your real-time driving vision under various conditions.
Cataract surgery: A safe & effective solution
Fortunately, cataracts can be treated with a simple and effective surgical procedure. Cataract surgery involves removing the cloudy lens and replacing it with a clear artificial lens (intraocular lens or IOL).
Benefits of cataract surgery for drivers:
- Improved vision clarity, reducing the need for corrective lenses.
- Enhanced night vision and reduced glare sensitivity.
- Increased contrast sensitivity for better depth perception.
- Overall improvement in driving confidence and safety.
- Faster reaction times to road hazards and improved peripheral vision.
Preparing for cataract surgery
If your cataracts are affecting your ability to drive, here’s what you need to do:
- Consult an ophthalmologist: Schedule an eye exam to assess the severity of your cataracts.
- Evaluate your driving needs: If driving is essential for work or daily activities, plan accordingly for recovery time post-surgery.
- Arrange transportation: After surgery, you’ll need someone to drive you home and help with transportation for a few days.
- Follow post-surgery care: Your doctor will provide specific instructions to ensure a smooth recovery, including avoiding strenuous activities and wearing protective eyewear.
- Check driving clearance: Before resuming driving, get a follow-up eye exam to confirm your vision has improved to legal driving standards.
