      What to Expect

Step 1: Self-Test, Consultations, Screening

Once we have determined that Scoptic Sensitivity Syndrome applies to your situation we can determine if the screening is an option.

Phase 1: Screening Process

     - typically takes 1 - 1.5 hours at the most 

  • Evaluates the severity of the light sensitivity

  • Evaluates the issues surrounding distortions when reading or doing other various tasks

  • Evaluates whether or not the issues identified will be amenable to the Irlen® Method

  • Identifies overlays that can be used to deal with reflected light frequencies only

  • Also provides information regarding the evaluation in case a report for school accommodations is required

  • Begins the education process for the client, it is very important the client understand what he / she is experiencing so that we can adjust the colors moving forward

  • Provides opportunity for parents / adults to gauge how much further into the process they wish to proceed based on the results

  • Any paperwork required will be exchanged before or at the time of the appointment 

If the screening above is indicating glasses will be useful then we will move into the Phase 2 Diagnostic Assessment.

Phase 2: Diagnostic — typically takes 2-3 hours 

  • Time varies greatly based on sensitivity of the client, may be longer if there are other medical conditions or factors are influencing the situation

  • Provides full tinting process that deals with most offensive light frequencies, not just the reflected frequencies covered by the overlays

  • Provides information on the type of glasses that will be needed 

  • Provides continued education and experience with light frequencies which is critical for knowing when the tints have stopped working and need adjustments (the brain does shift over time, younger people tend to shift more frequently because they are still growing)

  • May reveal other items or issues that were not present during the screening process

  • Recent eye exam recommended (within past year)

  • Any paperwork required will be exchanged before or at the time of the appointment

Reports and Evaluations

  • Reports for schools or the work environment will include everything pertaining to appropriate accommodations 

Maintenance Phase (Tint Checks) — Once phase 1 and phase 2 tests are complete you will move into the maintenance phase

  • Average tint check is approximately 1 per year

  • If things change quicker you may schedule earlier

  • Future orders will be based on requests you make as you move forward in the tinting process

  • A typical trend of note is that younger people tend to change tints more frequently because they are still growing
