If it does it would be good to hear an explanation.............
I don't see how extra light coming in to your eyes would make any bleeding occur or get worse.........
could be wrong though......
Light whose wavelength is in the visible spectrum (featuring safe intensity levels) doesn’t cause any harm coming into our eyes, with or without retinopathy. Photoreceptors in the retina actually work in the opposite way we could expect, meaning that the membrane of those cells depolarise in absence of light stimuli (i.e., scotopic conditions = darkness) whilst hyperpolarise in the opposite case (i.e., photopic conditions = light). It’s basically a “switching off” mechanism that activates the photoreceptor in order to transmit photons, absorbed and converted into an electric excitatory signal, to the next neural cell along the pathway to the optic nerve for the image generation of the surrounding world in our brain. Despite such an unusual mechanism reduces the incidence of spontaneous depolarisation in the retinal cells, therefore it reduces the "noise" that would plague our visual images, the metabolic rate of the retina is much higher in scotopic conditions.
Sorry if I was too technical but I’m a bioengineer working in Eye and Vision Science at Liverpool University Hospital and I’ve been type 1 for about 17 years now. Still trying to find a way out, if not from diabetes, at least from the long-term complications that this is going to cause us. An interesting device, based on the theory I’ve briefly explained above, is the Noctura 400 manufactured by PolyPhotonix. The device is a sleep mask that is worn at night and is giving positive results as a non-invasive treatment for diabetic retinopathy. I’m using the mask for prevention purposes as I can’t really think at a life with no sight. More info are available here:

Btw I'm also a video-games lover but Mr D has changed my philosophy of life: less virtual-games more real-games (i.e., outdoor sport)!
