RevitalVision Training Instructions
Congratulations on starting your RevitalVision therapy program!
You are about to start a unique vision training program that is scientifically and clinically proven to improve vision in diverse eye diseases and vision conditions. RevitalVision science is based on the concept of perceptual learning and brain plasticity.
In order for the program to be effective in improving your vision, it is very important that you follow all the training instructions described below.
Please note that continued repetitive training according to instructions will ensure optimal results, while long interruptions may disrupt, reduce or prevent clinical outcome.
Training Instructions:
RevitalVision will challenge and train you with different visual tasks. Each training unit will measure your maximum vision in a specific visual task. If you cannot see the stimuli, just guess, the software needs your answer in order to find your vision threshold. Once found, it will continue to the next training unit.
- Try to maintain your focus and reach the lowest possible contrast. In each task, the software will take several measurements; try to be consistent with your answers.
- You should train 3-4 times per week (every 2 days), in sequence, in a totally dark room, sitting five feet distance (1.5 meter) from the screen.
- Please use a measuring tape to measure the distance from your eyes to the screen and maintain the same distance throughout the entire training session.
- An average training session takes approximately 30 minutes. You should perform a minimum of 12 training sessions per month.
- During the 2–3-month program, you should not take a training brake for longer than 10 days (a single break of maximum 10 days during the 3 months therapy program, if needed).
- Depending on the program you are doing, there are specific instructions for using prescribed optical correction, special training glasses, or not using glasses at all. Please read your relevant instructions:
Amblyopia
You should wear your prescribed glasses or contact lenses all day during waking hours for the 3-month training program, even if it does not improve your vision initially. You should practice RevitalVision while blurring the strongest eye with a semitransparent white cover, and open the eye underneath the cover during training. This enables some stimulation to the opposite side of your brain.
Example of a semitransparent white cover
If you have amblyopia in both eyes (bilateral amblyopia), you should start the program with both eyes open, and after completing 40 training sessions, your doctor will instruct you to start monocular training after resetting the program to fixate on your weaker eye.
40 training sessions in a 3-month period.
Eye Disease / Low Vision
You should wear your prescribed glasses or contact lenses all day during the 3-month training program. If you are treating both eyes, start the program with both eyes open, and after completing 40 training sessions, your doctor will instruct you to start monocular training after resetting the program to fixate on your weaker eye.
40 – 60 training sessions in a 3-4 month period.
Post Cataract & Sports Vision
You should use your habitual daily (distance) correction if any. (With or without optical correction)
30 training sessions in a 2-month period.
Post LASIK, Low Myopia & Early Presbyopia
You will receive instructions before starting the program, whether you need to practice without optical correction at all, or with special training glasses (-0.5 or -1.00). If you are doing the presbyopia program and are using distance glasses, when instructed to use training glasses it will be clip-ons, which will be clipped to your prescribed distance glasses. Training glasses will be provided to you by the clinic or delivered to your address by the company.
30 training sessions in a 2-month period.
The room should be quiet without any external disturbances (no music, phone, friends, etc.). You should perform the training while you are feeling well, focused and alert. If you feel very tired, distracted or unfocused, we recommend delaying the training session to later when you feel ready or another day.
We recommend training before 10:00 p.m., because visual performance declines when we are tired.
Please be aware that improvement in vision can be slow and may not be noticeable daily. Only a follow up exam at the same clinic, can measure and confirm your clinical progress and outcome.
You should come to the clinic for a follow-up exam at mid program and at the end of the program- after final completion of 30 – 40 sessions (approximately 2- 3 months).
Detailed explanation:
Every session in your RevitalVision program is tailored to continually challenge your visual limitations. Using a special proprietary algorithm, the RevitalVision software generates each session for you based upon your beginning visual abilities, and then upon the outcome of each previously completed session. As such, this progression in the difficulty of your sessions will be unique to you and, likewise, the scoring of each session will be unique to you. Each session performance score you receive is a measure of how you performed against the level of difficulty presented during the visual performance tasks.
Every session you perform is designed to achieve an important goal to challenge your eyes and brain to see the faintest images possible. The “faintness” of these images is called a contrast level. The process of completing your prescribed RevitalVision program can be likened to walking down a flight of stairs. Imagine that each step in these stairs represents a level of visual ability. As such, the “top step” for you may not be the same as it is for others. During each session, once the RevitalVision software confirms that you can see an image, the contrast level is slightly lowered thereby taking you down another step. This continues until you can no longer see the image, at which point the RevitalVision software takes you up a step.
Once the RevitalVision software determines where your “bottom step” limit occurs, it will continue to work your eyes and brain at this level adjusting contrast levels ever more slightly. This is where the improvement in your eyesight takes place. It is working with you to overcome this limit. The next session you perform may not begin at your previous step and may not end with your previous “bottom step.” Because each session is tailored to your individual progress, it will naturally continue to work with you at a pace appropriate to your level of improvement.
After completing a training unit, you will see a score page containing three scoring parameters: (1) Correct answers – a counter of your total correct answers. (2) Quality – your ability to reach low contrast. (3) Consistency – your ability to provide consistent answers to identical tasks. Incorrect responses made around your “bottom step” are normal, the software expects you to make mistakes at your vision threshold. Other errors are considered on the basis of whether they occur consecutively. In order for the training to be effective, you should make efforts to provide consistent answers. While people with different vision abilities have different threshold points, it is important to know that your ability to reach low contrast may impact the effectiveness of the program. Training at low contrast will most likely lead to vision improvement, while training at high contrast may have very limited impact on vision, if at all. Although the highest session score possible is 100, achieving such a score is difficult and should not be expected.
As you consider your overall session performance score please keep these things in mind:
- Do not be worried about making mistakes. During your sessions it is expected and anticipated that you will make incorrect choices. This is how the RevitalVision software learns to accommodate your needs.
- Contrast levels will adjust automatically. If you happen to make a mistake at a higher contrast level, do not be concerned. As you make subsequent correct selections, your image contrast levels will go down again.
- Scores will differ for each session. If you receive a lower overall score than you did for a previously completed session, again, do not be concerned. Each session is different and attempts to challenge you harder.
Scores can mean more than visual performance. A lower score could mean that you are tired or unable to concentrate. Use your scores to help you assess what factors may be contributing to your level of effort.
It’s not about the score. Completing your RevitalVision program is not about getting the highest score, but rather about your own personal vision improvement. Scores are provided to guide and inform you. They are not an indicator of success or failure.
