Frequently Asked Questions

Q: What is an eye occluder used for in optometry?

A: A handheld eye occluder is used during vision screenings and refraction assessments to block one eye at a time. This allows the optometrist or technician to evaluate each eye independently, producing more accurate visual acuity and refraction measurements without interference from the non-tested eye.

Q: What is the difference between the frosted transparent and black eye occluder?

A: The frosted transparent occluder allows a diffused level of light through while still blocking clear vision, which can be useful in certain optometric screening protocols. The black occluder provides complete blockage of light and vision to the covered eye, making it the standard choice for most visual acuity tests.

Q: Is this eye occluder suitable for home use or only professional settings?

A: While this eye occluder is designed to meet professional optometry standards and is widely used in clinics and eyewear shops, it can also be used in supervised home vision screening situations. It is a simple, battery-free handheld tool that requires no special setup.

Q: What material is this eye occluder made from?

A: This eye occluder is made from PP (polypropylene), a lightweight and durable plastic that is easy to clean and maintain. The frosted finish provides a professional look while ensuring a sturdy, long-lasting build.
