Key Points made by Dr. Zigler about Dry Eye Causes & Treatment:

• Dry eye is considered a syndrome clinically, however, it is a symptom of an underlying inflammation of the body.
• Dry eye causes and treatment focuses on reducing the underlying causes of inflammation in the three parts of the eye – cornea, conjunctiva, and eyelids.
• Pharmaceutical treatments for dry eye only reduce inflammation of the eye without getting to the root cause of the underlying disease.
• It is important to switch to organic, non-GMO fruits and vegetables and focus on green leafy vegetables.
• All meals are based around spinach and kale because they have a very high amount of lutein that helps with eye health by reducing inflammation.
• It is recommended to focus on vegetables as the main dish and meat as condiments.
• Add fruits, nuts, seeds and legumes to make a wholesome meal.
• Avoiding milk is important, as it is inflammatory.
• Other ingredients to avoid are sugar, canned foods, anything in a box and processed foods, which are highly inflammatory.
• A basic recipe for a smoothie for two – one banana, three handfuls of spinach, a little bit of almond milk and water. You could add avocado, chia seeds, flax seeds and then some frozen fruits, like berries.
• It takes about a week to see changes in eye health after transforming to a plant based diet, because switching from the modern diet will have a period of withdrawal symptoms, similar to quitting smoking or alcohol.
• With the “Green Smoothie Challenge” after the initial withdrawal symptoms of detoxing in a week or two, one will start to see results and feel incredible in six months.
• Day 1-7 is the “unbearable stage” with the challenge, where you will have more gas, poop more and feel awful, and you might hate the smoothies.
• Day 7-14 of the challenge is called the “uncomfortable stage”, where you will not feel great but you will start to feel better.
• Day 14-21 is the “unstoppable phase”, where you actually start to crave your green smoothie and feel worse if you stop because your body will start to miss the nutrients.
• One could get addicted to artificial sweeteners as well as stevia in protein powders and end up with headaches and other problems.
• It is important to hydrate well first thing in the morning with 16-32 ounces of water. This is called the “Hyper-hydration stage”, which boosts your metabolism by about 30% and puts the body in a feel-good state.
• Drinking about 16 ounces of water before every meal helps jumpstart your digestive system by lubrication.
• Using computers and smart devices we expose ourselves to blue light even at night, which keeps us awake longer and reduces deep sleep at night.
• Shutting off electronics and wearing blue light blocking glasses two hours before bedtime will increase melatonin production to help you go to sleep faster and deeper into restorative REM sleep.
• Blue light is emitted with any device that has a flat panel, including televisions.
• People can install blue light filters on smart devices starting at 7 or 8pm so that your brain and body starts making enough melatonin as part of your sleep-wake cycle.
• Prescription glasses can be made with 20-30% blue-light blockers and are s...
