I'm experiencing eye strain / CVS symptoms and would like to get computer glasses ASAP, but can't get in to see an eye doctor for months, so I'm coming here in the hopes someone can answer my question. I currently wear glasses and my prescription is -0.50 cylinder for both eyes, no sphere value or ADD value (I only have astigmatism). I'm on eyebuydirect and selected intermediate reading glasses, but am unsure if I should be putting anything for ADD value. I've seen online that for computer distances (30 inches away in my case) a good ADD value is somewhere around +0.25 to +0.75. Would this basically just add some magnification to my existing prescription, or would it screw up my prescription if I added an ADD value without getting evaluated for that at the eye doctor? Any recommendations for what specific value to..ADD? In addition to magnification I'm getting anti-glare, but am leaning towards no blue-light filtering since I've heard it doesn't do much and I've already turned down the blue light in my screen settings.

Thanks!
