Oxidative stress significantly affects health and vision. It is a process in which free radicals are produced, leading to potential harm as these unstable molecules steal electrons from healthy cells. This oxidative damage can manifest visibly as aging skin and ocular changes, such as cataract formation. However, oxidation is not the only factor contributing to accelerated aging and eye conditions; poor circulation and insufficient essential nutrients also play important roles.
Ultraviolet (UV) rays are a major external factor that promotes oxidation. Continuous exposure to sunlight without protective eyewear can increase oxidative damage in the eyes over time. This exposure can harm retinal cells and may lead to various eye conditions, including macular degeneration. Therefore, protecting the eyes from UV rays is crucial for maintaining eye health.

Physical exercise is vital for eye health and overall health. Research shows the positive impacts of exercise on common eye conditions. What is the intricate relationship between exercise and eye health? Can regular physical activity reduce the risk of age-related eye diseases? What role does nutrition play? And, can physical exercise help stave off neurological disease, heart disease, and other chronic illnesses associated with aging? At Natural Eye Care, we want to support you with knowledge and practical tips for getting the exercise you need. 
Dry eyes are among the most prevalent issues reported by our customers and patients. Women experiencing perimenopause and menopause frequently have dry eyes. However, it is increasingly observed across all age groups, largely attributable to prolonged use of digital devices such as computers, laptops, tablets, and smartphones. [1.

Americans are spending at least 5 hours per day close-up looking at computers, tablets and smartphones.[1. 
Electronics have become primary obsessions in our personal and work lives. This has lead to nearly everyone becoming susceptible to Computer Vision Syndrome. Symptoms include dry eyes, eye strain, blurred vision, headaches, double vision, difficulty in concentrating, fatigue and/or and head, neck and shoulder pain.
