I've seen two doctors who took a look at my eyes and said everything's healthy, and that I'm just experiencing age-related presbyopia (I'm 43m). My symptoms are as follows: * My eyes become dry very quickly if they are open at a normal width. * Due to the above, I spend much of the day with my eyes in a fairly squinted configuration. * I cannot read, eg, text on my phone without squinting. * Covering one eye (particularly my left eye) seems to improve my vision. * My eyes often hurt / burn, especially in the evening. * I have gnarly floaters in my left eye. * Reading glasses are not much help; in order to benefit from them, I need to open my eyes more, which makes them very dry within 60 seconds. * My eyes are often red and cloudy, especially in the morning. * I occasionally wake up during the night from pain / dryness in my eyes. * Unlike what I understand is typical for presbyopia, my vision does not degrade throughout the day, and is often a bit better at night. Observations about things that have changed this: * Sub-freezing temps seem to bring about a fairly fast (ie, within 1-2 days) and dramatic relief. Each year for the past few, I've gone to Colorado in mid-Feb for three weeks or so, and these are the best vision weeks of the year. However, I spend much of my time in Florida, so I rarely encounter cold temps. * The drops that the doctor puts in to dilate pupils seem to trigger dramatic improvement, lasting 1-2 days. * Spending time outside and using an RLCD monitor in the sun does seem to bring about some pain relief, but even multiple days in a row of this don't seem to improve my up-close vision or eye dryness. I've tried searching every term I can think of, and as I say, I've seen multiple doctors (though I'm happy to go again). If anybody has any insight, I'd really value it. I'm struggling with this.
