This early morning I could finally test my anti headlights glasses. They are quite effective. You can now set the lights on without even blinking. Also the small retinal persistence is also eradicated. If you're wondering what I mean doing this simple little experiment. Attach any lamp at then look away. For a few seconds you have a glow that gradually fades. Well it is removed through these glasses. So for those who were wondering, you can buy without fear. Excellent value for money.
