You can think of it that way: the amount of sensory experience generated by the dream is proportional to the amount you care about, and that you would be open to receive and remember. For example, if someone seldom uses their sense of smell, then they will have few dreams where this sense is used, like a dream taking place in a greenhouse, where they stop smelling each plant/flower. In the same way, your amount of awareness of a certain sense determines how much of that sensory you will receive during any dream.
So, the main idea would be developing awareness of sight, and consequently, dream recall. It all starts with dream recall, you see the more you are willing to record, the more will present to you.
Therefore, my suggestion for you would be stating before bed, “My dreams are vivid and clear”, and prepare yourself for some nice recall
When you are lucid in a dream, then you can intervene on the spot, just shouting “Increase vividness!” or playing around with dream properties, like focus and brightness, like it was some sort of monitor/virtual experience
