I’m in my late 30s and started having debilitating headaches around Christmas time which was completely unheard of for me. As per NHS England advice, I visited my optician thinking I would need stronger glasses and ended up going straight to casualty. They said there was extra pressure on my eyeball and it is supposed to be less than 20, but mine was 43. The optician explained it well, as did the casualty doctor, but I was so overwhelmed I struggled to take it and really don’t understand it. What is the pressure from? I was told it can be blocked because there’s so much pressure but why would there be pressure on my eyeball at all? I was told mine was very high, is it something I should be worried about or is it quite a normal problem on the scale of eye problems? The optician looked worried when the tests showed the pressure on my eye was 43 and he said it doesn’t happen very often, has anyone else on here ever had this experience? I’ve never had problems with my eyes before and thought I may just need some stronger glasses so it was a shock and I’m just slightly worried about it as I don’t fully understand it.
