Needing glasses Watch
Hi , my prescription at the moment is-0.25 and I am 15 years old , I am currently revising for my exams and my vision has got worse - next time I go to the opticians is there a possibility I will need to wear glasses all the time due to needing to sit at the front in every lesson where the board is still a bit blurry
Up to you how much you where them. You may find you only need it in class but there is nothing wrong with wearing them 24/7
I have a similar prescription to you and was told to wear my glasses whenever they would help me (if the thing I'm trying to look at is blurry) to avoid straining my eyes and making my vision worse. However, you shouldn't wear them literally all the time because looking at something close up (eg reading a book) with your glasses on will also strain your eyes. Looking at revision close up for hours can make your vision temporarily worse though, and it might recover when you finish revising, so make sure to tell your optician what you have been doing in case it affects your prescription. To avoid permanently affecting your eyes I heard you should follow the 20/20/20 rule: every 20 minutes of looking at something up close, get up and focus on something at least 20 metres away for 20 seconds.
