Response from developer
Hello, this is team Edenlux. Thank you for taking the time to write a review. TV Mode can be used during distant vision activities for 40cm or more, such as watching TV or enjoying a landscape while relaxing. Phone Mode can be used during near-work vision activities under 40cm such as looking at smartphones or reading books. To set up and switch the Phone/TV mode, press the Mode Switch Button placed on the left of the Otus device. If you need further details and instructions for TV mode, kindly contact us via email at cs@edenlx.com, then we will help you out by going through each step of the setup. Thank you.
