Background Obesity is a chronic metabolic disease that has become an epidemic today. Objective Although the effects of obesity on the body have been well studied, less is known about obesity and eye health. Methods The present article is a review study. The search was performed using keywords of obesity and eye diseases in PubMed, Scopus, Web of Science databases from 2000 to 2021. Results Obesity is a significant public health problem, and its impact on eye health is increasing. So far, the association of obesity with dry eye, cataract, glaucoma, age-related macular degeneration, and diabetic retinopathy has been reported with varying degrees of certainty. Conclusion If weight loss as a complementary treatment proves to be an effective way of delaying the onset or slowing the progression of eye diseases in obese people, physicians and patients are more likely to be more motivated to combat this public health problem.
