ICantSee - Visual Field Test

ICantSee is a free, privacy-first app designed to help you test and track your visual field – the area you can see without moving your eyes.
Whether you are monitoring a known condition (such as glaucoma, retinal issues, or optic nerve damage) or simply checking your vision, ICantSee makes it simple to follow changes over time.

How it works:
• Complete a quick grid-based visual field test: spot the target letter and mark any invisible areas.
• Adjust grid size and zoom for your comfort.
• Save your results and review your history anytime.
• View easy-to-read evolution graphs.
• Export a detailed PDF report (marked grids, graphs, and history) to share with your eye doctor.

Why choose ICantSee:
• 100% offline – your data stays on your device.
• No account, no ads, no data collection.
• Designed for accessibility with large, clear text.
• Free to use – no hidden fees.

Ideal for:
• People living with glaucoma, macular degeneration, retinal diseases, or other vision issues.
• Eye care professionals wanting a quick tool for in-office checks or patient follow-up.
• Anyone wanting to keep track of their vision over time.

ICantSee does not replace a professional eye exam. Always consult a qualified eye care professional for diagnosis and treatment.
