Three essential vitamins for eye health, says ophthalmologist

Ophthalmologist Oksana Kuznetsova has emphasized that vitamins A, C, and E are essential for normal eye function, warning that deficiencies can cause poor night vision, dry and fatigued eyes, retinal damage, and cataracts.

She added that vitamin supplements should only be taken under medical supervision, noting that while they do not cure vision problems, a deficiency—combined with other factors—can contribute to certain eye diseases. For example, vitamin A is particularly important for vision, as its deficiency can make it difficult to see in low light and for the eyes to recover from bright light exposure. However, it should not be taken without a prescription, according to Russia Today.

Vitamins C and E, she explained, have antioxidant properties and help protect the retina from oxidative stress. For this reason, they are used alongside zinc, copper, lutein, and zeaxanthin in pharmaceutical formulations to treat certain eye conditions.

Kuznetsova continued that these medications are not intended to improve vision, but are prescribed for patients diagnosed with intermediate-stage age-related macular degeneration. Such supplements are not recommended for healthy individuals unless their health condition specifically requires it.
