17‑Pinholes Occluder

The 17‑Pinholes Occluder is a versatile diagnostic tool used by eye‑care professionals to quickly differentiate between refractive errors and pathological causes of reduced visual acuity. By allowing light to enter through multiple small apertures, the occluder minimizes the impact of optical aberrations and helps determine the patient’s best potential vision.

This tool is commonly used during routine eye examinations, low‑vision assessments, and pre‑refraction screenings. Its lightweight, ergonomic design ensures comfort for both clinicians and patients, while the evenly distributed pinholes provide consistent and reliable results.

Key Features

• 17 precision‑cut pinholes for accurate visual acuity assessment
• Reduces refractive blur by limiting peripheral light rays
• Helps identify refractive vs. pathological vision loss
• Lightweight, durable construction suitable for daily clinical use
• Ergonomic handle for easy positioning and patient comfort
• Ideal for refraction rooms, low‑vision clinics, and screening camps

Applications

• Rapid assessment of potential best‑corrected visual acuity
• Differentiation of refractive errors from retinal or neurological causes
• Low‑vision evaluation
• Pre‑refraction screening in clinics, hospitals, and outreach programs
