Cataracts can affect both eyes or just one, and some patients experience mild symptoms, while others can barely see any shapes or movements.

Cataract symptoms include blurry vision, haloes, sensitivity to bright lights, decreased night vision, frequent changes in eyeglass prescriptions, and faded colours.

Cataracts can be caused by trauma, diseases such as diabetes or medications such as steroids.

If you’re diagnosed with a cataract, your ophthalmologist will recommend an outpatient surgical procedure.

There are two types of IOLs: monovision (fixed-focus for a preset distance) or multifocal (focused vision at various distances).

Salmon, sardines and other fatty fish like trout, mackerel and herring are a very unique family of foods containing essential nutrients simply not found elsewhere. These fatty fish are the only foods in our food system that naturally contain large amounts of Vitamin D3 as well as the long-chain omega-3 fatty acids EPA & DHA.

A single 75 gram serving of any fatty fish has close to a full day’s supply of both Vitamin D3 and omega-3, two nutrients which many people don’t get enough of.

These long-chain omega-3s, particularly DHA, are concentrated in the human retina and are generally found in significant supply throughout the eye.

There has long been scientific interest in the role omega-3s play in maintaining vision and eye health, with observational studies demonstrating that people who eat more fish tend to have a lower risk of age related macular degeneration and cataract.

The Mediterranean Diet, known to be one of the best eating styles for long-term health, calls for at least 500 grams of fish per week for optimal long-term health.

Fatty fish like salmon and sardines are actually among the lowest mercury fish which means their regular consumption is considered safe for the vast majority of people.
