NoIR (F465#21) Large Flip-Up Clip-Ons: 81% Yellow

The NoIR F465 Large Flip-Up Clip-On Sunglasses in 81% Yellow are a leading choice among people who struggle with glare, contrast sensitivity, and light adaptation — particularly those with macular degeneration, cataracts, diabetic retinopathy, and general photophobia. The 81% visible light transmission yellow filter dramatically enhances contrast and depth perception in lower-light environments — such as overcast days, indoor fluorescent lighting, and nighttime settings — while still blocking 100% of UV rays and 90% of blue light.

The large, flip-up frame design attaches directly to most existing prescription eyeglasses, giving patients the flexibility to flip the filter up instantly when stepping into or out of different lighting conditions.

Key Features:

• 81% yellow visible light transmission — enhances contrast, improves depth perception
• 100% UV protection — blocks all UVA and UVB rays
• 90% blue light blocking — reduces digital and fluorescent light fatigue
• Large frame size — provides broad coverage for maximum glare control
• Flip-up design — attaches to prescription glasses; flip up to remove instantly
• Clip-on mechanism — fits most prescription eyeglass frames
• Recommended for: cataracts, macular degeneration, poor vision in darker conditions, and contrast sensitivity loss

Ideal for: individuals with low vision who need enhanced contrast and glare protection indoors and in low-light settings.
