Night Driving Glasses: Enhance Your Safety on the Roads
Driving at night can be more demanding than driving in daylight. Lower light levels make contrast harder to see. Headlights and reflections from wet roads can create distracting glare. This affects drivers with good vision and people using glasses or contact lenses.
Night driving glasses are marketed to make dark driving more comfortable. However, not every type works the same way. Yellow or amber lenses are often promoted. But reducing light in dark conditions may not be helpful.
What Are Night Driving Glasses?
Night driving glasses are designed specifically for use in low-light conditions. They may include a prescription or an anti-reflective coating. Some feature a light tint or a combination of these.
The most familiar versions often have yellow or amber lenses. These filter certain light wavelengths to increase perceived contrast. Changing the appearance of contrast does not always improve your ability to see objects.
Do Yellow Night Driving Glasses Really Work?
Yellow night driving glasses are advertised to reduce glare and improve contrast. Evidence for general improvement is limited. Additionally, tinted lenses reduce some light entering the eye.
This is important at night when eyes have less light available. Some tinted lenses may be unsuitable for darkness. An optician can advise if a particular tint is appropriate.
In other words, darker or more strongly coloured lenses should not automatically be considered better for night driving.
Can Anti-Reflective Lenses Help with Night Driving?
Anti-reflective coatings are different from tinted lenses. Instead of deliberately reducing incoming light, an anti-reflective treatment reduces reflections from the surfaces of spectacle lenses.
This is useful because lights may create reflections in the glasses. Clear prescription lenses with anti-reflective treatment may be more useful. A yellow tint is not always the best option.
The most important factor is still that the prescription itself is correct. Special coatings cannot compensate for an outdated or unsuitable prescription.
Why Does Driving at Night Become More Difficult?
Several factors can make vision more challenging after dark. Your pupils become larger in low light, and contrast is reduced compared with daylight. Bright headlights can then create a strong difference between the light source and the darker surroundings.
Vision problems may also become more noticeable at night. These can include:
- Uncorrected or under-corrected myopia
- Astigmatism
- Presbyopia and difficulty seeing the dashboard or navigation display clearly
- Dry eyes
- Changes in the eye such as cataracts
New glare or blurred vision should be checked by a professional. Do not assume that special glasses will solve the problem.
Can Astigmatism Make Night Driving More Difficult?
Yes. Astigmatism can cause lights to appear blurred or stretched. You may see streaks and halos around headlights and streetlights.
Correcting the astigmatism accurately is therefore important. This can be done with suitable glasses or, for people who prefer contact lenses, with toric contact lenses.
A special pair of night driving glasses cannot replace the correct astigmatism prescription.
Can You Drive at Night with Contact Lenses?
Yes. Contact lenses work if they provide the correction you need. They are often comfortable to wear. They do not have surfaces that create reflections and provide an unobstructed view.
People with astigmatism may use toric lenses. Those with presbyopia may suit multifocal contact lenses depending on their needs.
Contact lenses do not, however, make everyone see better at night. Dryness can make vision fluctuate or make lenses less comfortable, particularly towards the end of a long day. If this happens regularly, discuss your contact lens fit, material or wearing schedule with your optician.
How Can You Reduce Glare When Driving at Night?
Glasses are only one part of the picture. Several simple measures can make night driving more comfortable and help reduce unnecessary glare:
- Make sure your glasses or contact lens prescription is up to date
- Keep your windscreen clean on both the inside and outside
- Keep spectacle lenses clean and free from excessive scratches
- Adjust mirrors to reduce reflections from vehicles behind you
- Avoid looking directly at the headlights of approaching vehicles
- Take breaks during long journeys, especially when tired
- Have your eyes examined if night vision changes significantly
Are Night Driving Glasses Worth It?
That depends on what is meant by night driving glasses. A pair of correctly prescribed clear glasses with an effective anti-reflective coating may help reduce distracting reflections for some drivers.
Yellow or amber lenses are different. They may increase perceived contrast. However, they reduce light transmission and may not improve performance.
Contact lens wearers normally do not need non-prescription night glasses. Focus on accurate vision correction and comfortable lenses. Regular eye examinations are also a priority.
Night Driving Glasses: What to Remember
Night driving glasses are not a universal solution to glare or poor night vision. Correct vision correction is more important, and anti-reflective treatments on clear prescription glasses may be useful for reducing reflections.
Ensure your contact lenses provide clear vision for driving. If headlights appear more blurred or dazzling, have your eyes checked. Do not simply try a stronger tint.
