Experiencing Halos and Night Glare After 50? TECNIS PureSee™ vs. Traditional EDOF Lenses for Night Driving in SoCal

Headlights that once seemed manageable can become distracting rings or bursts of light after 50. If night driving around Orange or Irvine feels more difficult, an eye evaluation can help identify why. At Coastal Vision Medical Group, we help patients understand their symptoms and compare cataract lens options around their everyday needs.

Why Halos and Night Glare Develop

Cataracts cloud the eye’s natural lens, scattering light and making headlights appear brighter or surrounded by halos. Other vision problems, including an outdated prescription, can also contribute. Age alone does not determine whether you need cataract surgery.

We start by examining your eyes and identifying what is affecting your vision. When cataracts interfere with driving or other daily activities, surgery may be appropriate. During surgery, we replace the cloudy lens with an intraocular lens, or IOL.

What Traditional EDOF Lenses Offer

Extended depth of focus, or EDOF, lenses expand the range of useful vision, particularly from distance to intermediate tasks such as viewing a computer screen. Reading glasses may still be needed for small print.

“Traditional EDOF” describes several designs, not one uniform lens category. Some earlier EDOF lenses use diffractive optics to extend focus. These designs can produce halos, glare, or starbursts, and some may reduce contrast sensitivity under certain conditions. Other EDOF lenses use non-diffractive technology, so comparisons should focus on the specific lens.

How TECNIS PureSee™ Is Different

TECNIS PureSee is an EDOF lens with a purely refractive design. It extends focus through its optical shape without using diffractive rings.

Clinical evidence supporting its FDA approval showed improved intermediate vision while maintaining distance vision and contrast sensitivity comparable to an aspheric monofocal lens. Its visual disturbance profile was also similar to a monofocal lens.

That combination may appeal to patients who want more range than a standard monofocal lens while prioritizing visual quality. However, PureSee can still cause halos or glare, and reading glasses may remain necessary. These findings do not establish better night-driving performance than every other EDOF lens.

What Matters for Night Driving in SoCal

For patients traveling between Long Beach, Chino, and other Southern California communities after dark, lens selection involves more than reading an eye chart. We discuss:

• How often you drive at night and how much headlights bother you

• Contrast sensitivity, which helps distinguish objects from their background

• Astigmatism and other eye conditions that may affect surgical results

• Your priorities for distance, computer, and reading vision

• Your willingness to wear glasses for certain activities

Choosing a Lens Around Your Eyes

We evaluate your eye health, measurements, and visual goals before recommending a lens. PureSee may suit some patients, while a monofocal or another lens design may better fit others. No implant guarantees glare-free night driving.

If glare makes driving feel unsafe, avoid driving after dark until your vision has been evaluated. Sudden halos accompanied by eye pain or reduced vision require urgent care.

If halos and night glare are changing your routine, schedule a cataract consultation with Coastal Vision Medical Group in Orange, Irvine, Long Beach, or Chino, CA, by calling (888) 501-4496. We can help you explore lens options with your night-driving needs in mind.
