Eye occluders & medical eye patches
The eye occluder, explained — and the patch made to actually wear
An eye occluder is a simple device that covers one eye. Clinics use one for a moment during a vision test; people who need daily coverage want something they can live in. This page explains what an eye occluder is, what it’s used for and the types that exist — then points you to handmade leather occluder eye patches by Anudra.

What is an eye occluder?
An eye occluder is any device that blocks vision in one eye so the other can be tested or treated on its own. The word describes the job — to occlude, or cover. In everyday language people also call it an occluder eye patch, an ocular occluder or a vision occluder, and the same idea covers a handheld paddle in a clinic and a wearable patch worn at home.
In ophthalmology and optometry, an occluder is a standard exam tool: the clinician covers one eye while you read a chart so each eye’s acuity is measured separately, and uses it in cover tests for strabismus (a turned eye) and amblyopia (lazy eye). Separate from the exam is occlusion therapy — deliberately patching the stronger eye for hours a day to strengthen a weaker one. That’s where a comfortable, wearable occluder patch matters.
Types of eye occluders
✓Handheld (clinical) occluder
A paddle the clinician holds up for the few minutes of an eye exam — the classic occluder in ophthalmology and optometry.
✓Opaque occluder
Fully blocks light and vision — used for occlusion therapy and whenever complete coverage is needed.
✓Pinhole occluder
Has a small central hole, used in refraction tests to check whether blurred vision improves.
✓Adhesive patch occluder
Stick-on disposable patches, common for children’s amblyopia patching.
✓Wearable leather occluder patch
A reusable, comfortable patch made to be worn for hours or every day — what Anudra makes.
What eye occluders are used for
✓Eye exams
Covering one eye so a clinician can measure each eye’s visual acuity separately during a sight test.
✓Amblyopia (lazy eye) therapy
Patching the stronger eye so a weaker “lazy” eye is encouraged to develop, most often in children.
✓Strabismus assessment
Cover and cover-uncover tests help evaluate how the eyes align when checking for a turned eye.
✓Post-surgery protection
Shielding an eye while it heals, when an eye-care professional recommends it.
✓Light sensitivity
Reducing the light reaching a sensitive eye for day-to-day comfort.
✓Everyday wear
Daily coverage after eye loss or when one eye is not in use.

Eye occluder FAQ
What is an eye occluder?
An eye occluder is any device that blocks vision in one eye so the other can be tested or treated on its own — from a handheld clinical paddle to a wearable occluder eye patch. The word simply means to occlude, or cover, one eye.
What does “occluder” mean?
“Occluder” comes from occlude — to close or cover. In eye care it means a tool or patch that covers one eye; you’ll also see it called an ocular occluder, a vision occluder, or an occluder eye patch.
What is an occluder used for in an eye exam?
To cover one eye so each eye’s vision is measured on its own, and to test eye alignment in cover tests that screen for strabismus and amblyopia. In an exam the occluder is handheld and used briefly.
What is the difference between an occluder and an eye patch?
“Occluder” usually means the clinical tool used briefly during an exam, while “eye patch” more often means something worn for hours — for therapy, protection or every day. A leather patch is the wearable kind of occluder.
How does patching treat a lazy eye (amblyopia)?
Covering the stronger eye pushes the brain to rely on the weaker one, encouraging it to develop. Dose and duration vary by person and age, so follow your eye-care professional’s guidance.
Which eye should be covered?
For a vision test each eye is covered in turn. For therapy it depends on the diagnosis — typically the stronger eye is patched — but this should be decided with your eye-care professional.
Can I wear an occluder patch over glasses?
Often yes. Because our patch domes outward and doesn’t sit flat on the eye, there’s room underneath for many glasses; position the patch first and route the strap above or below the temple arm.
How much does an eye occluder cost and where can I buy one?
Anudra’s handmade leather occluder patches start at €34. Buy them here at MokVok, or on our Etsy (AnudraStudio) and Amazon (ANUDRA) stores, with worldwide shipping.
