This is a 2-month study in which eligible ADHD adolescents will be provided with personalized VIZO Glasses
This is a pilot, open-label study of a 2-month treatment with VIZO Glasses. Following the enrollment, the participants will go through an adjustment process where they will be fitted with a personalized pair of VIZO Glasses. The participants will be instructed to wear the glasses throughout the day for two months. A follow-up visit at the end of the 2-month treatment will be conducted to assess the efficacy of VIZO Glasses on managing ADHD symptoms, using the ADHD Rating Scale (ADHD-RS) parent-report questionnaire, the Behavior Rating Inventory of Executive Function (BRIEF), the Conners Continuous Performance Test-3, and the Clinical Global Impression-Improvement (CGI-I). Safety will be monitored by documentation of adverse events.

Change in the ADHD Rating Scale (ADHD-RS) Parent-report Questionnaire - Total Score - at Baseline and 2 Months Follow up
The ADHD-RS is a parent report questionnaire that is used to aid in the diagnosis of ADHD in children ranging from ages 5-17. The questionnaire contains 18 symptom items corresponding to the DSM-V criteria for ADHD. The parent rates each symptom item on a 4-point Likert scale ranging from 0 ('Never or Rarely') to 3 ('Very Often'). The total score goes from 0 up to 54. Higher scores mean more symptoms and higher ADHD impairments.
Time frame: Baseline, 2-month
Change in the ADHD Rating Scale (ADHD-RS) Parent-report Questionnaire - Inattentiveness Subscale - at Baseline and 2 Months Follow up
The Inattention subscale of the ADHD-RS contains 9 symptom items, that are designed to measure the child's attention level on tasks or play activities.The items are rated by the parent on a 4-point Likert scale ranging from 0 ('Never or Rarely') to 3 ('Very Often'). The total score goes from 0 up to 27. Higher scores mean more symptoms and higher ADHD impairments.
Time frame: Baseline, 2-month
Change in the ADHD Rating Scale (ADHD-RS) Parent-report Questionnaire - Hyperactivity-Impulsivity Subscale - at Baseline and 2 Months Follow up
The Hyperactivity-Impulsivity subscale of the ADHD-RS contains 9 symptom items, that are designed to measure the child's hyperactivity level and impulsivity level. The items are rated by the parent on a 4-point Likert scale ranging from 0 ('Never or Rarely') to 3 ('Very Often'). The total score goes from 0 up to 27. Higher scores mean more symptoms and higher ADHD impairments.
Time frame: Baseline, 2-month
Change in Behavior Rating Inventory of Executive Function (BRIEF) - Metacognitive Index - at Baseline and 2 Months Follow up
The Metacognition Index (MI) of the BRIEF reflects a child's ability to self-manage and monitor tasks cognitively. The subscale is composed of the Initiate, Working Memory, Plan/Organize, Organization of Materials, and Monitor scales of the BRIEF. It uses a Likert-type response format ranging from 1 to 3, where 1 is never, 2 is sometimes, and 3 is often. The MI subscale includes 40-items with score ranges between 0 to 120. Higher values represent worse outcome and greater difficulties with executive functions. High scores indicate executive deficit.

Clinical Global Impression-Improvement (CGI-I) - at 2 Months Follow up
Based on an interview with the participant, the clinician rates the total improvement on a 7 point scale as follows: 1=very much improved since the initiation of treatment; 2=much improved; 3=minimally improved; 4=no change from baseline (the initiation of treatment); 5=minimally worse; 6= much worse; 7=very much worse since the initiation of treatment.
Time frame: 2-month
Change in Behavior Rating Inventory of Executive Function (BRIEF) - Global Executive Composite - at Baseline and 2 Months Follow up
The BRIEF is a standardized measure that captures views of executive functions or self-regulation in the everyday environment. The BRIEF is composed of 86 items, where each item is rated by the parent, using a 3-point Likert scale ranging from 1 ('Never') to 3 ('Often'). Total score ranges between 86 to 258. The Global Executive Composite (GEC) is an overarching summary score that incorporates all of the BRIEF clinical scales. High scores indicate executive deficit.
Time frame: Baseline, 2-month
Change in Conners' Continuous Performance Test-3 (CPT-3) - Detectability (d') at Baseline and 2 Months Follow up
Conners' Continuous Performance Test-3 (CPT-3) is an objective test of attention and impulsivity that has been validated in individuals aged 8 years and older. d-prime (d') is a measure of how well the respondent discriminates nontargets (i.e., the letter X) from targets (i.e., all other letters). This variable is also a signal detection statistic that measures the difference between the signal (targets) and noise (non-targets) distributions. In general, the greater the difference between the signal and noise distributions, the better the ability to distinguish non-targets and targets. CPT scores are age and gender standardized T-scores, in which the mean is equal to 50 and the standard deviation is equal to 10. d' is reverse-scored so that higher raw score and T-score values indicate worse performance (i.e., poorer discrimination). Atypical scores are higher than 60 indicating "elevated" to "very elevated" performance.
