When driving at night, it is strongly recommended that you wear '''full correction''' glasses, that are more powerful than your normalized. Leave no room for error. | When driving at night, it is strongly recommended that you wear '''full correction''' glasses, that are more powerful than your normalized. Leave no room for error. | ||
You only need two pairs of glasses. Don't wear loads of different pairs of normalised and differentials for different focal distances, you only need two. | You only need two reduced pairs of glasses.
