As part of the Functional Vision Evaluation, it is essential to observe the student’s natural learning environments to understand how environmental factors support or hinder the use of vision. These observations provide insight into how a student’s visual performance varies based on lighting, contrast, color, spatial layout, and organization. 

​Make Environmental Observations

When completing the Functional Vision Evaluation (FVE), it is important to document the specific locations where observations and assessment activities occurred. This helps the educational team understand how the student uses their vision across different environments. For each setting, include descriptive information such as:
  • Lighting conditions: Note whether the environment used natural light, artificial light, or a combination. Describe the brightness level (bright, moderate, dim), the direction of the light source, and whether the lighting created shadows or glare.
  • Object size and material type: Record the size, color, contrast level, and tactile characteristics of the materials used during assessment activities—for example, small manipulatives, print sizes, high-contrast symbols, digital text, or classroom objects.
  • Viewing distances: Specify the distances at which tasks were assessed, including near (within arm’s reach), intermediate (3–6 feet), and distance/far (6 feet or more).
  • Use of prescribed glasses or optical devices: Document whether the student wore their prescribed corrective lenses, sunglasses, or optical aids. Note the type, strength, and intended purpose of the device (e.g., bifocals, +6D dome magnifier, monocular telescope).
  • Visual behavior and performance: Describe how the student used their vision in each environment, including posture, head tilt, eye movements, scanning patterns, distance preferences, fatigue, or use of compensatory strategies. Include observations about efficiency, accuracy, and level of independence.
These detailed observations allow evaluators to make accurate, meaningful recommendations for accommodations, environmental adjustments, specialized instruction, and appropriate learning media.

​​Lighting Observations

When assessing lighting, it is important to consider the student’s visual diagnosis, as certain eye conditions influence how a student responds to brightness, glare, contrast, and overall visual clarity. Conditions such as albinism, aniridia, cataracts, retinitis pigmentosa, cortical visual impairment (CVI), and many others can affect light sensitivity, visual efficiency, and fatigue. Because of this, lighting should be evaluated thoughtfully and systematically across environments. Take note of the following:
  • Lighting Type. Record the types of light sources present and how the student responds to each. Different lighting types vary in brightness, warmth, color, and flicker, all of which can affect comfort and performance.
    • Natural sunlight – may offer excellent contrast but can create glare or overly bright conditions.
    • Incandescent bulbs – warm, steady light that may be comfortable for some students.
    • Fluorescent lights – common in schools but can flicker or create discomfort for students with specific diagnoses.
    • LED lighting – energy-efficient but varies widely in brightness and color temperature.
    • Halogen lights – very bright, may cause glare but provide strong task lighting.
    • Mixed light sources – combinations of natural and artificial light can create inconsistent lighting or shadows.
  • Light Controls. Document the availability and use of features that help adjust lighting to meet the student's needs.
    • Window treatments: shades, blinds, or drapes that reduce glare or brightness.
    • Uncovered windows or skylights: may increase natural light, glare, and shadows.
    • Dimmer switches or adjustable lamps: allow fine-tuning of lighting for tasks requiring precision or reduced brightness.
  • Lighting Quality. Evaluate how well the lighting supports visual clarity and comfort.
    • Adequate vs. too dim or too bright: Determine whether lighting enhances or hinders visual performance.
    • Even or uneven distribution: Uneven lighting or patchy shadows can interfere with tracking, reading, and mobility.
    • Shadowed or high-glare areas: Identify locations where glare from windows, screens, glossy surfaces, or polished floors impacts visibility.
Understanding how lighting influences a student’s visual functioning ensures appropriate recommendations for classroom seating, task lighting, environmental modifications, and compensatory strategies.

Glare Control

When evaluating how a student uses their vision, it is essential to identify any sources of glare that may reduce visual clarity, cause discomfort, or increase fatigue. Glare can come from direct light, reflected light, or shiny surfaces, and it often impacts students with diagnoses such as albinism, aniridia, cataracts, corneal issues, or cortical visual impairment (CVI). Glare may wash out contrast, obscure print, or make it difficult for the student to focus on tasks. Be sure to take note of glare caused by:
  • Electronic screens. Devices such as TVs, computer monitors, tablets, laptops, and interactive smartboards can produce glare—especially when positioned near windows or under bright overhead lighting. Screen angle, brightness settings, and screen reflectiveness all play a role.
  • Whiteboards or laminated materials. These highly reflective surfaces can produce intense glare from overhead lighting or natural sunlight. Students may struggle to read writing on a glossy board or see images on laminated cards or worksheets.
  • Polished floors or tabletops. Waxed floors, shiny desks, or smooth tables can reflect overhead lights or sunlight, creating bright spots that interfere with visual comfort and orientation.
  • Mirrors or glass surfaces. Mirrors, glass doors, trophy cases, display cabinets, or glossy wall art can reflect surrounding lights and produce distracting or uncomfortable glare.
  • Sunlight reflecting off windows or objects. Direct sunlight or light bouncing off nearby cars, buildings, white walls, or classroom objects can create intense reflections. This may affect visibility when the student moves through hallways, sits near windows, or works at certain tables.
Documenting glare sources helps make effective recommendations such as adjusting seating, repositioning materials, using window coverings, modifying lighting, or incorporating anti-glare screens or matte finishes.

​Color and Contrast Observations

When conducting the Functional Vision Evaluation, it is important to evaluate the color and contrast of the environment, as these factors greatly influence how well a student can identify objects, navigate spaces, and access instructional materials. High contrast can support clarity and independence, while low contrast or visually complex environments may lead to confusion, missed details, or safety concerns. Environmental Color and Contrast to Observe:
  • Wall color, floor covering, furniture, and doors. Take note of whether these surfaces provide distinct visual separation or if they blend together. For example, a dark door against a light wall offers strong contrast and is easier to locate than a door that matches the wall color.
  • Contrast between key environmental features:
    • Doors and doorframes. Well-contrasted frames make entryways easier to identify, particularly in hallways or multipurpose spaces.
    • Floors and walls. Strong contrast improves navigation and depth perception, while similar colors can make edges or corners hard to detect.
    • Furniture and background. Desks, chairs, shelves, and storage units should ideally stand out from the floor and wall colors to aid identification and reduce tripping or collision risks.
    • Handrails and walls. High-contrast handrails make stairways and ramps safer, especially for students with low vision or decreased peripheral vision.
  • Clarity vs. Visual Confusion. Consider whether the overall environment promotes visual clarity—through clean lines, simple backgrounds, and good contrast—or whether it contributes to visual clutter or confusion. Busy patterns, multicolored walls, heavily decorated bulletin boards, or crowded shelves may overwhelm students with low vision or reduce their ability to locate important information. Minimal, predictable layouts often support better visual processing.
  • Additional Considerations for Students with Cortical Visual Impairment (CVI). Students with CVI may respond differently to color and contrast than students with ocular visual impairments. During observation, note whether certain high-saturation colors, especially red or yellow, grab the student’s attention more effectively. Also, observe if simplified, single-color backgrounds help the student visually isolate an object. Make note whether visually complex or cluttered surroundings increase fatigue, distractibility, or difficulty locating targets.
Documenting color and contrast helps guide recommendations for environmental modifications, material design, seating placement, and instructional strategies that support visual access and safety.

Organization and Safety Hazards

Assess how the organization of the space may impact visual efficiency:
  • Is the environment orderly or cluttered?
  • Are materials easy to locate?
  • Are visual and physical distractions minimized?
Document any potential safety hazards:
  • Electrical cords or wires in walking paths
  • Items on the floor that may cause trips
  • Cabinets or drawers left open
  • Poorly defined transitions between floor surfaces

​Recommendations for Students with Lighting Difficulties

Based on the observations, include tailored recommendations in the report. These may include:
  • Adjust general lighting (dim, medium, or bright)
  • Provide task lighting for close work
  • Reduce glare (e.g., using matte finishes, repositioning materials)
  • Permit use of sunglasses, visor, or tinted lenses
  • Recommend sunscreen and protective clothing for outdoor activities
  • Allow extra time for visual adaptation when transitioning between lighting conditions
  • Adjust window blinds or curtains as needed
  • Position student away from glare-producing windows or lights
  • Instruct teachers to avoid standing in front of windows while teaching to prevent “backlighting.”
​These observations and recommendations are essential in understanding how the environment influences the student's ability to use vision and in creating an accessible learning space tailored to their needs. When paired with functional performance data, they help guide effective accommodations, instructional planning, and environmental modifications.
