early stage keratokonus, if this is true you need to get the corneal crosslinking procedure done asap while you are young as the condition progresses rapidly in your 20s. The double (triple, N-ary) vision can be corrected by special contact lenses. You may need a specialist ophthalmologist for this diagnosis. https://en.m.wikipedia.org/wiki/Keratoconus see “signs and Symptoms” image, and note that is advanced, as a 19yo I recall a single, sharp double image when looking at the moon at night. You can also try lowering an index card in front of your eye and looking across the edge at the moon and seeing if the double image goes away when your eye is partially occluded, this is because the doubling is caused by a physical distortion of your cornea and if you manage to cover the distortion you will see clearly
Shit, It did match, looking at the text through the edge of a card does make it clear for me. Although the blurriness is not as extreme as given in the wiki page.
https://www.reddit.com/r/Keratoconus/ -- but do not freak out, most cases are completely treatable with scleral contact lenses, social media bubbles up the outliers. Next step is ophthalmologist, ask for a corneal topography (photograph and measure the surface shape of your eye w/ a computer) to establish a baseline and monitor for progression. Not all ophthalmologist offices have the corneal topography machine so ask for that on the phone. https://en.wikipedia.org/wiki/Corneal_topography To get a KC diagnosis they will likely want to see progression over time in these topography readings. You want to get this sorted while you are young, the corneal cross-linking procedure will halt the progression of the disease and "lock in" your current vision. I did not get the CXL procedure when I was young (it was still experimental back then) and regret it, my vision is fine with correction but the scleral lenses are a pain and it's unclear if i'll be able to read in bed without lenses in my old age.
I was recently diagnosed with keratoconus, I'm 28.
I'm unable to get CXL for at least a year due to demand.
What sucks the most about the diagnosis is that the opthalmologist explained that there's essentially no treatment, it's progression can only be slowed, and I'll never be able to get LASIK or SMILE.
