Electronics Really Can Damage Your Eyes
Can electronics really damage your eyes? The answer is yes. New evidence shows that the blue light emitted from computer screens, tablets, TVs, smartphones, and modern lighting like CFL and LED bulbs can cause retinal cell death. Over a lifetime of cumulative exposure, this damage can lead to macular degeneration, a leading cause …
What Are the Three Macular Carotenoids?
Lutein, zeaxanthin, and meso-zeaxanthin are the only three carotenoids found in the human eye. They’re concentrated in the macula, the central part of the retina responsible for sharp, detailed vision. Each has its own specific location: lutein dominates the outer macula, RR-zeaxanthin is found in the mid-peripheral area, and meso-zeaxanthin is concentrated right at the …

As people age, vision often changes gradually. Common early effects include needing brighter light to read, seeing colors as less vivid, and taking longer to adjust between bright and dim environments. These changes reflect age-related stress within the retina. Over time, the retinal pigment epithelium becomes less efficient at supporting photoreceptors, delivering nutrients, …
