Are there any supplements that improve night vision or vision in general? i am taking bilberry fruit extract but its not improving anything.

VITAMIN A: is the major "supporter" of NIGHT VISION and there are a number of eye supporting nutritional/vitamin Preparations.. Ask you Pharmacist for a recommendation! Hope this is helpful Dr Z

Supplement: Economic boom. Many supplement manufacturer claim to achieve great eye health even with glaucoma but none of that is substantiated. Unless you have Vitamin deficiency which is unlikely with the American diet additional vitamin supplements is a waste of money and may have adverse effects. Maintain a healthy diet and see you eye doctor. May need error of refraction correction
