I'm really needing some advice from those who have been there or who are currently there

My DS is 7 years old, he has been seeing optometrists, behavioural optometrists & specialists from the age of 5 for a turn in his eye. We have been seeing a great behavioural optometrist who has helped a lot and we have also attended The Private Eye Clinic for specialised advice. I'm doing my best to understand exactly what these 'specialists' are talking abut but I must admit I struggle to fully comprehend it all.

The turn is in his right eye, it turns in when he tries to focus from a distance and is quite noticeable when he doesn't have his glasses on. It is not related to tiredness (as some can be). As a result of the turn in his eye his vision was suffering and he has been wearing glasses for 2 years. The glasses were to help with the vision as well as hopefully strengthen the turn in his eye. His eyes weren't functioning together, when trying to focus the right eye would turn, therefore vision not great and as a result the brain would 'switch off' the use of the right eye.

Last year (his first year of school) he went through with no issues at all, he was confident and capable of all that was asked of him. Although the behavioural optometrist appt he had late last year showed some stalling of continued improvement so we were sent off to the specialist again. That was this week and we have now been told to fill a prescription for bi-focal glasses for him. He was fairly confident that this would be successful although he did say that with the line in the glasses it could be quite noticeable to his classmates and it may be something he receives "attention" about. I'm hoping it's 'friendly attention' and not the opposite. He said by the age of ten he could be able to wear contact lenses and then by 20ish he could have laser surgery. So my husband and I took all that in but all the while thinking.... "what about the turn??" If I am understanding all this correctly this is to help his vision but is it going to straighten his eye? I have no issue with my son wearing glasses and so far neither does he, he has never once complained about wearing them but being so young and having the rest of his life ahead of him we would truly love to fix the turn in his eye. We questioned this and I explained how we were not concerned with him wearing glasses but would like for the turn to be fixed, we were heard but not offered any other options.

We are aware of the surgery available to do this and are not quite sure why this isn't being offered to him. I don't want to put my son through any unnecessary pain but what about his emotional health? I'm not trying to be too hung up on my son being slightly different from the rest but we all know that kids can be cruel and I don't my son to (potentially) go through something that could be avoidable. What I'm all worried about may never happen but being a mum brings a long so much worry and you just can't help it.

So I'd love to hear of anyone who has personal experience with dealing with any similar cases and how the people they saw for guidance regarding this dealt with it. I'm not sure if we try for another opinion, my MIL thinks we should and I think my husband would like to. I don't want to look like parents who are going from doctor to doctor to try and get what they want and as well as that it costs a whole lot of money.

I just need some help, thanks ladies
