I'm 36wks pregnant and for the last few weeks I sometimes suddenly find that the lights in the lounge become very bright and I find it hard to focus. The lights themselves aren't changing, it's just after maybe an hour of watching tele or using the laptop I suddenly find them overpowering and I feel like I need to dash for my shades. I've had my vision checked and its fine, no probs.
Can anyone explain this? Could it be a lack of sleep thing? DP and friends/family have never heard of it.
