Many optometrists are expanding their traditional roles to include other areas that affect eye health, such as nutritional education.
Research has shown that certain nutrients can delay the development and progression of cataracts and age-related macular degeneration (AMD). These are two of the leading causes of blindness and visual impairment for millions of aging Americans.
Nutrition may be particularly important in treating AMD. Currently, treatment options after diagnosis of this condition are limited.
Also, people who suffer from dry eye, an increasing problem due to the visual demands of digital devices, can often benefit from nutritional supplements.
