Like overall health, eye health issues can become complicated if you only focus on one possible cause. For example, occasional dry eye is more than a contact lens discomfort or a lack of tears. It’s a multifaceted concern that could have several causes and contributors, and most of the time, regular fish oil supplements are not enough to relieve all of the symptoms.
Fish oil supplements contain just that: fish oil. Typically suggested for heart concerns, they are not specifically made to relieve occasional dry eye symptoms. The main reason fish oils are prescribed for dryness and irritation is for the Omega-3s. Eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) are some of the most important fatty acids found in fish oils, but it could take patients 4-7 pills per day to get the amount of Omega-3s needed for relief.
