Hi @dietgourmet. Thank you for your response. I have read some of the causes for photophia can be eye strain and eye dryness. Constant darkness can make it worse not better. I do get relief briefly from the lubricant eye drops and sunglasses. I discovered blocking the blue light emanating from light bulbs also helps, particularly fluorescent bulbs. The blue light can also be filtered from the Ipad and Iphone screens. These are some of the steps I took today. I am glad you found a solution that works best for you and thank you for sharing.
