Difference Between Comprehensive Eye Exam and Developmental Eye Exam

Updated: Sep 24, 2023

A developmental vision and comprehensive eye exams differ in their focus and scope. Here are the key distinctions between the two:

Purpose and Focus:

  • Developmental Vision Exam: This type of exam assesses visual skills and abilities related to development and learning. It evaluates visual processing, visual-motor integration, visual perception, and other visual functions that impact academic performance and daily activities.

  • Comprehensive Eye Exam: This exam primarily focuses on assessing the eyes' overall health and determining the need for prescription lenses. It includes checking visual acuity, determining refractive error (nearsightedness, farsightedness, astigmatism), and examining the eye structures for any signs of disease or abnormalities.

Evaluating Visual Skills:

  • Developmental Vision Exam: The emphasis is on assessing visual skills such as eye teaming, tracking, focusing, convergence, accommodation, visual memory, visual motor integration, and visual perception. These skills are crucial for efficient reading, writing, comprehension, and learning.

  • Comprehensive Eye Exam: The primary focus is on evaluating visual acuity (clarity of vision), determining refractive error, and examining the eye structures for any signs of disease or abnormalities. It may not include detailed assessments of specific visual skills related to learning difficulties.

Specialist Training:

  • Developmental Vision Exam: It is typically conducted by optometrists with additional training and expertise in developmental and behavioral optometry or vision therapy. They are knowledgeable about the visual aspects of learning and how vision impacts academic performance.

  • Comprehensive Eye Exam: It is typically performed by optometrists or ophthalmologists who specialize in general eye care and diagnosing and treating eye diseases. They may not have specialized training in assessing visual skills related to learning difficulties.

Evaluation Techniques:

  • Developmental Vision Exam: This exam may involve a variety of specialized tests, including assessments of eye movements, binocular vision, accommodation, visual perception, and visual processing. It may also include observations of the child's visual behavior during various activities.

  • Comprehensive Eye Exam: The focus is on standard procedures like visual acuity testing, refraction, examination of eye health, and screening for eye conditions. It may involve tests like using an eye chart, autorefractor, tonometry (eye pressure measurement), and dilation of the pupils to examine the internal structures of the eyes.

Visual Perception

Both exams have their own significance and serve different purposes. If a child is experiencing learning difficulties, attention problems, or other visual concerns impacting academic performance, a developmental vision exam may be recommended in addition to a comprehensive eye exam. The developmental vision exam provides a more comprehensive assessment of visual skills relevant to learning. In contrast, the comprehensive eye exam ensures overall eye health and provides accurate vision correction if needed.
