I've had a number of visual processing and light sensitivity issues after BI. The visual processing, pattern glare, was treated successfully with colorimetry methods, it took 14 months.
At the beginning of March I was retested and a pair of transition lenses were prescribed, for sensitivity to bright sunlight, with a clear to grey to green colour change. They also have varying focal elements to improve peripheral vision.
They arrived by post earlier in the week. I put them on and went out into the bright sun, my brains did not turn to scrambled eggs but just stayed 'normal', I felt really calm. It took a few days to get used to the feeling of walking on air and seeing everything clearly in my field of vision.
I am now laying in the sun every day (while it shines) getting a tan for the good of society during the covid lockdown.
The effects were instant and life has changed dramatically for the better again. A very big thanks to my optometrist.
