I believe this is down to the fluid levels in the eyes being altered through osmosis. When the sugar levels in the blood are high, fluid will seep back from within the eyes into the bloodstream. This will alter the size of the eyeball and thus affect the ability to focus. All the organs and tissues in our bodies are effectively dehydrated to a degree by surges in blood sugar and this causes significant stress to them. After a while the new sugar levels equalise in the blood and organs and the correct fluid levels are restored. With low blood sugar levels fluid will be drawn into the organs and tissue from the bloodstream by the same process.</p></blockquote><p></p>
