The superfood that helps combat blurred vision and dry eyes

The retina is the light-sensitive layer at the back of the eye, and plays a crucial role in vision. Omega-3 fatty acids are important components of retinal cell membranes, and adequate consumption can help maintain the health and function of this vital tissue, contributing to clear, sharp vision.

Macular degeneration is an eye disease associated with aging that affects the macula, the part of the retina responsible for central and detailed vision. Studies have suggested that omega-3 fatty acids may help reduce the risk of developing age-related macular degeneration and slow its progression in people who already have it.

Blurred vision can be caused by a variety of factors, including dry eyes, inflammation, and poor health of the blood vessels in the eye. Omega-3 fatty acids have anti-inflammatory properties and can improve blood circulation in retinal vessels, which can help prevent blurred vision and improve visual acuity.

• Fatty fish: Fatty fish such as salmon, tuna, mackerel, and sardines are excellent sources of omega-3 fatty acids, especially EPA and DHA. It is recommended to consume fish at least twice a week to obtain an adequate intake of these nutrients beneficial for eye health.
• Nuts and seeds: Walnuts, chia seeds, flax seeds, and hemp seeds are rich in alpha-linolenic acid (ALA), a type of omega-3 fatty acid that the body can convert to EPA and DHA to some extent. Adding these nuts and seeds to your daily diet is a great way to increase your omega-3 intake.
• Fish oil: Fish oil is a concentrated source of EPA and DHA, and is available in supplement form. Taking fish oil supplements may be a convenient option for those who have difficulty getting enough omega-3 fatty acids through their diet.
