Line Eyes is the ultimate companion for your fertility journey. Our advanced image processing algorithms help you see faint lines on pregnancy and ovulation tests that the naked eye might miss. Beyond image enhancement, we provide a suite of medical-grade calculators and community tools to support you from TTC to BFP.

Enhance Your Test Strip Images

Our web-based tools help you analyze test strips more effectively by providing various image enhancement options. Whether you need to see faint lines more clearly or adjust contrast for better visibility, Line Eyes has you covered.

What features does Line Eyes offer?
  • Grayscale & Invert: High-contrast modes to make faint lines pop.
  • Tweakers: Fine-tune brightness, contrast, and sharpness.
  • Heatmap (Pro): Visualizes dye density to distinguish evaps from real lines.
  • Ghost Mode: Overlay previous tests to track progression perfectly.
  • Cyan Filter: Neutralizes pink dye runs to see the test line clearly.
How does Line Eyes help with test analysis?

Early pregnancy tests often have extremely faint lines that are hard to capture on camera. Our tools manipulate contrast, brightness, and color channels to make these lines stand out against the background. We also provide tools to align and stack images, creating a clear visual history of your line progression over time.
