I wear specs at all times. I recently tried a pair of orange-tinted, plain-lens safety specs worn on top of my own glasses in the evening to see if it might help my insomnia but I couldn't keep them in place. I'm wondering whether to splash out on a prescription pair but because I have a very high prescription I can only have fairly small lenses. I'm wondering if the specs would therefore let too much light in at the sides to be effective. Any advice?
