For the last two years I've been suffering with extreme dry eyes. I've tried everything and to keep it under control I've been using a daily combination of medicated eye wipes, drops, spray, warm compress with duct massage, high dose of fish oil. And I daren't get close to a heater or air conditioner. I remembered that Eye Bright is an old remedy for eye issues so thought I had nothing to lose in trying this. Dry Eyes Plus has been amazing. I've dropped everything else except fish oil and spray and the whole eyeball anguish has dropped back to 10% of what it previously was.
