Hello This could be due to many causes like refractive error or some other retinal disease It is very difficult to comment without examining you Kindly consult local ophthalmologist and get proper eye examination done Regards

please get your eyes testing done. and use lubricant eye drops 2to3 times daily e.g. teardrop.

What you are experiencing seems to be a serious problem only. And its really good you could appreciate it soo well. You need to do your visual fields test, contrast sensitivity, color vision test. You can also test your colour vision using online tests. If color vision totally normal.. it might not be very serious. But consult ophthalmologist asap. Immediately.
