New lighting exam technology is a clinic changer
The LuxIQ™ is the first calibrated exam tool to provide task lighting assessments and recommendations. Optimal light is important for functional vision. The LuxIQ uses light levels and color temperatures to quantify vision performance and light tolerance.
People who squint
Published studies show that many need bright light of 2000-5000 lux to maximize acuity. A typical desk lamp provides only 800 lux; an exam room 600 lux. Most adults need more task light and/or less glare for near acuity. Some children are photophobic and need less task light to succeed in school. The LuxIQ makes it practical to vary intensity from 0 to 5000 lux and color temperature from 2700 to 6500°K—without swapping hot bulbs or changing fixtures. Use it to:
- Determine task lighting needs without trial and error
- Recommend optimum lamps and/or light bulbs
- Educate patients in lighting concepts
- Determine impact of color lighting
- Chart patient lighting changes over time to observe disease progression
People with dry eye
“I had no idea how consistent photophobia is in patients with dry eye disease.”
Harvey Fishman, MD, PhD in Ophthalmology Times
Many patients with dry eye experience light intolerance. Doctors can use the LuxIQ to baseline light sensitivity and track the impact of dry eye treatment. Dry eye patients have been shown to consistently prefer substantially lower light levels (1000 lux and lower) vs. normals (3000 lux and higher) before treatment. As an example, one patient who initially preferred 1000 lux later preferred 4000 lux post-treatment.
