Thanks for your reply. I don’t wear my glasses when I’m on my computer because I’m able to see the screen clearly but after some time my eyes get really red and start feeling dry. When I do wear my glasses my eyes feel a bit strained too but everything is really clear. I’m not sure if this is because my glasses are too strong or if it’s because I don’t wear them very often. If I go for a walk outdoors without my glasses and it’s a sunny day my eyes feel a better/more relaxed. Not sure if this is relevant but my optometrist seemed surprised my eyes got so bad because at my last appointment when I was younger I had perfect vision so I’m not sure what’s going on. I think my eyes looked fine otherwise from the eye test. I also noticed that when it’s really nice weather and sunny that a blurry object in the distance can become really perfectly clear briefly then it looks blurred again if I blink or move my eyes a little. This is without squinting my eyes. Is this a symptom of poor eyesight or just a lot of eye strain? Could I have an accomadative spasm?
