Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
The main questions the study aims to answer are:
* Does vision training improve dimensions of functional vision?
* How does vision training affect the participants's perception of functional vision and the ability to compensate for visual field loss? Researchers will compare the effect of home-based vision training to standard care (no vision training) on functional vision.
Participants will:
* Participate in home-based vision training or standard care for 8 weeks
* Be contacted once a week by phone
* Keep a training diary

Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
The overall aim is to obtain knowledge about the effects of compensatory visual rehabilitation strategies on functional vision in people with stroke who do not meet the health prerequisites for visual field, as defined in the Driving licences regulations in Norway. Specifically, to describe the effect on functional vision and the compensatory vision strategies related to traffic situations. Secondary, to explore markers for perceived functional vision and functional visual field that may predict an effect of visual rehabilitation.
DESIGN:
The study will be performed as an open, controlled and randomized trial with semi-cross-over design. The participants will be allocated to an immediate- or delayed intervention following a pre-randomized list. The participants are allocated to immediate intervention (Fast track; Group A) will be investigated at baseline, after 8 and 20 weeks. The remaining participant are allocated to delayed intervention (Delayed start; Group B) will start the intervention 8 weeks after the baseline and investigated at baseline, week 8, week 20 and week 28.
SETTING /RECRUITMENT The study sample will consist of adults with post-stroke visual field defects. All the three sub-studies will have the same study sample.

RANDOMIZED
PARALLEL
Fast track, group A: Fast track participants will receive the intervention immediately after baseline assessments. The intervention are 8 weeks of home-based training exercises for eye movement-, visual scanning-, and visual search exercises to learn compensatory strategies for visual field loss. The investigators will use a licensed online vision training program (Vision Builder) and manual paper-based exercises. Daily vision training will consist of 20 minutes with total minimum recommended training 2h/week for 8 weeks.

Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Fast track - Group A
Individual home-based vision training exercises for 20 minutes every day for 8 weeks. A training program with online and manual oculomotor exercises, scanning and visual search-exercises. Weekly short follow up-conversation by telephone to check in and keep the motivation high with the participants.
Compensatory scanning training
Individual home-based vision training exercises for 20 minutes every day for 8 weeks. A training program with online and manual oculomotor exercises, scanning and visual search-exercises. Weekly short follow up-conversation by telephone to check in and keep the motivation high with the participants.
Delayed track - Group B
Delayed track - group B will receive the intervention with a delayed 8 weeks start up. Individual home-based vision training exercises for 20 minutes every day for 8 weeks. A training program with online and manual oculomotor exercises, scanning and visual search-exercises. Weekly short follow up-conversation by telephone to check in and keep the motivation high with the participants.
Delayed Compensatory scanning training
Delayed track start. Individual home-based vision training exercises for 20 minutes every day for 8 weeks. A training program with online and manual oculomotor exercises, scanning and visual search-exercises.
