Firstly I would suggest a visit to your option. If you’re struggling with headaches etc this can impact your eyes, similarly with squinting and excessive use of computer screens. I am sure there are some glasses which opticians can give you “blue light glasses” which are specifically for people who have extensive periods using computers. Failing that, I would recommend laser eye surgery. This is something I had done myself last year my prescription was -5.50 and -5.75 in each eye with an astigmatism and it has changed my life. I know it is pricey but if this could be an option for you I would highly recommend, I went through optical express and corrected my vision to better than 20/20 and also removed my astigmatism.
