A Comprehensive Guide to Standardized Visual Acuity, Pediatrics, and Low-Vision Rehabilitation
Since the 1970s, Precision Vision has built an unparalleled reputation for manufacturing the most accurate and durable vision testing tools available. In the 1980s, we printed the first official ETDRS cards and introduced the industry-standard retro-illuminated ETDRS cabinet. Since the 1990s, we have expanded our catalog to support an extensive variety of pediatric and low-vision assessment configurations.
This classic handbook introductory text, compiled by noted vision rehabilitation researcher Dr. August Colenbrander, delivers essential guidance for selecting specialized targets from the vast array of commercial eye charts available today.

Public Health Advisory
Decorative Contact Lenses May Cause Permanent Eye Damage
Whether aiming to mirror a favorite celebrity, replicate a cinematic performer, or coordinate the ideal look for a festive costume event, choosing to insert non-prescription cosmetic contact lenses carries extreme pathogenetic risk. Unregulated decorative lenses purchased via retail novelty channels frequently induce severe corneal ulcers, microbial keratitis, and baseline hypoxia, resulting in permanent vision impairment.
Clinical Triage Insight
Preventing Depression from Age-Related Vision Loss
Roughly 2 million Americans aged 50 and older navigate severe low vision secondary to Age-Related Macular Degeneration (AMD)—a primary catalyst for permanent visual loss—while millions more manifest early-stage Drusen formations. AMD compromises the structural integrity of the macula lutea near the central retina. As geographic atrophy expands, a growing central scotoma emerges, heavily impacting mental wellness and requiring targeted low-vision rehabilitation support.
Study Shows Correlation Between Nearsightedness and Education
Evolving epidemiologic studies suggest that environmental behavior and cumulative educational exposure exert a significantly higher statistical weight on the development of progressive myopia than baseline genetic predisposition.
Data sets demonstrate that with each consecutive scholastic school year successfully completed, an individual's refractive error scales along a more negative dioptric path. This clear link underscores the immediate clinical necessity for structured outdoor balance interventions across K-12 learning environments.
Ocular Surface Health and Cosmetic Safety Concerns
Ophthalmic regulatory frameworks continue to stress that eye color modulation via internet-sourced cosmetic contacts presents unnecessary danger to corneal health parameters.
Because these devices circumvent a physical fitting session by an optometrist or ophthalmologist, they fail to match a patient's exact sagittal depth or base curve coordinates. A poorly fit contact lens functions as a mechanical abrasive layer across the delicate corneal epithelium, paving an open path for aggressive structural tissue complications.
