Poor vision is a common problem among various populations around the world. Moreover, I've already written that these problems are getting worse year after year due to our poor lifestyle, where we spend half our lives staring at a smartphone or computer...
One cause of vision impairment can be a deficiency of vitamin B2 (riboflavin). Doctors who read even a little medical literature might immediately object that this vitamin deficiency is rare, and of course, they would be wrong.
The fact is that its deficiency can be caused not only by poor nutrition but also by genetics. This condition is called RTD (Riboflavin Transporter Deficiency) and is associated with polymorphisms in the SLC52A gene family.
So, people with a deficiency of this vitamin experience interesting visual symptoms:
- High sensitivity to light
- Poor vision in the dark
- Blurred vision
- Feeling of sand in the eyes
If you experience these symptoms, don't expect medical help. You need riboflavin at a dosage of 50-100 mg per day. These dosages aren't available in pharmacies, but they are available in dietary supplements. Ideally, it should be combined with Aevit (Vitamin A + Vitamin E), but Aevit should not be taken more than 14 days per month. Riboflavin itself is water-soluble (unlike Aevit), so it's quite difficult to overdose. The most you'll experience with higher doses is yellow urine and mild bladder irritation. Vision effects will begin within a week of use (if riboflavin deficiency is the cause).
