Approved eye injections like Lucentis can be pricey. There are also not negligible side effects like cataract development in some cases and individual results may vary. A non-invasive treatment I came across not long ago and that I'm using on myself is called Noctura 400. It's available through a selected network of Optometrists who check the condition of the retina every 3 months. Noctura 400 is a sleep mask, which is worn at night to deliver a precise dose of light therapy during normal hours of sleep. The mechanism of action is still based on preventing VEGF production but different from the response triggered by the ingredients contained in the eye injections. You can find more info on this other thread of the forum:
