Hey It’s Kind of Blurry in Here

The lenses of your eyes are the wonderful, naturally engineered optical devices that are part of the ocular apparatus allowing you to view the world. The words you are now reading present images, focused by the lenses on your retina, then transposed into nervous system signals interpreted by your brain as black letter images on white background. Lenses are like diamonds: Without flaws, they are crystal clear, allowing the unimpeded passage of light. Pretty damn amazing, when you think about it.

Flawed, however, and the passage of light will be distorted.

Lenses consist of structural proteins called crystallins that, like all other proteins of the body, are subject to glycation. When proteins in the lenses become glycated and form AGEs, the AGEs cross-link and clump together. Like the little specks that can be seen in a flawed diamond, little defects accumulate in the lenses. Light scatters upon hitting the defects. Over years of AGE formation, accumulated defects cause opacity of the lenses, or cataracts.

The relationship of blood glucose, AGEs, and cataracts is well-defined. Cataracts can be produced within as little as ninety days in lab animals just by keeping blood glucose high.28 Diabetics are especially prone to cataracts (no surprise there), with as much as fivefold increased risk compared to nondiabetics.29

In the United States, cataracts are common, affecting 42 percent of males and females between the ages of fifty-two and sixty-four, and increasing to 91 percent between the ages of seventy-five and eighty-five.30 In fact, no structure in the eye escapes the damaging effects of AGEs, including the retina (macular degeneration), the vitreous (the gellike liquid filling the eyeball), and the cornea.31

Any food that increases blood sugar therefore has the potential to glycate the crystallins of the lenses of your eyes. At some point, injury to the lens exceeds its limited capacity for defect resorption and crystallin renewal. That’s when the car in front of you is lost in a blurry haze, unimproved by putting on your glasses or squinting.
