Photosensitivity reactions can occur in minutes, so it is important to take precautions to shield your skin and eyes from exposure. Talk with your doctor about what you can expect. You must be careful during the first 30 days after your injection to avoid bright lights and direct sunlight. You don't have to limit yourse to dark rooms, however, either in the hospital once you are back home. The lighting in your home should not be a problem, but do stay away from direct sunlight from skylights or undraped windows.
Most indoor activities are fine including watching television.
When reading, do not expose your skin to the light from a reading lamp- keep your skin covered. If at all possible, wait until sundown to do daily chores like shopping. If you go out during daylight hours, you must cover as much skin as possible. That means wearing a long-sleeved shirt, slacks, gloves, socks, shoes, and a widebrimmed hat. Wear tightly woven, light-colored fabrics, if possible.
