If you need to squint to see things better then this is a clear indicator that you have an ocular issue. That being said, it doesn’t necessarily have to be a symptom of hyperopia as other ocular conditions can also lead to squinting. That being said, if you only have to squint when looking at objects that are near you and don’t have to squint when looking at things that are further away then your squinting is more likely than not a symptom of your hyperopia.
It’s worth noting that squinting, in itself, doesn’t damage your eyes despite what some common myths may have you believe. Still, it’s a clear indicator that your eyes aren’t up to par in the vision department and likely require some form of correction. Rather than relying on squinting, it’s far more practical to just get your eyes checked and treat the actual issue at play.
