Even without something added for scale, it's usually instantly possible to tell when you're looking at a photo of something life-sized vs a (significantly) smaller scale model of it. What is it that our eyes/brain are doing here? [more inside]
I am really puzzled by my glasses prescription. The optician said my eyes had got worse, which makes sense since everything has been blurry lately. But when I looked at websites explaining glasses prescriptions, it actually looks like my eyes have improved. Also the optician said my new glasses will let me see 20/20 whereas my old glasses didn't. When I asked why the last optician I saw couldn't make me up glasses for 20/20 vision, she didn't know. Opticians of MeFi, please can you help explain this to me? [more inside]
I am moderately nearsighted and currently wear glasses with a prescription of roughly -3 in each eye. I take my glasses off to read, and always have. This is not because writing appears blurry with my glasses on, but because reading with my glasses on causes my eyes to strain, or feels like it does, and it has always just felt more comfortable to take them off. Does this make me a bad candidate for contacts or corrective surgery? Do I just need to get used to reading with my vision corrected? Is this something bifocals/bifocal contacts can address?
Last week I was diagnosed with type 2 Diabetes. Since then I've lowered my fasting blood glucose by over a hundred. Yay! But all of a sudden I can't see. Boo! [more inside]
I am an anthropologist-in-training who spends time in living with a community with a strong medicine-man institution. The medicine-men claim to see various sorts of spirits, and often in very casual settings, like during walks in the forest or while sitting in the house. They'll say stuff like, "there's one sitting right there. It's red with hair on top." I want to know - is there a scientifically compelling way to investigate whether they actually "see" spirits?

Anyone had any good experiences with an optometrist in Seattle that accepts Washington Apple Health? [more inside]
This evening, as I was making my way home, I looked up through my glasses and noticed that the Moon was not round, but oval in shape. However, when I squinted (which brings things into focus), the Moon became round. Now I don't know if my eyes have gotten much worse in the last two years, or if the prescription I was given was wrong. [more inside]
So tomorrow we will be bringing home our new kitten Matthew Meowdock. This will be my first ever kitten, and I'm trying to make sure he integrates into our household (including our existing dog and cat) reasonably easily. Difficulty: Matthew is completely blind. If you have or have had a blind cat, what do you wish you'd known at first? [more inside]
I am in my late 30s and have always been nearsighted/myopic. My prescription is -7.25 with (I am told a lot of) astigmatism. My vision is starting to change...I can see bifocals on the distant horizon. [more inside]
I need new glasses and sunglasses. Are transition lenses better than they used to be? [more inside]
I have an order in for some new ones, but they'll take up to a week to be delivered. And I just can't deal with the blinding headache and blurriness until then. The issue: my prescription is stronger than the lenses opticians have in stock. [more inside]
I have a new pair of glasses that I like just fine. Even though the prescription is a little stronger in one eye than that of my previous pair, I've noticed that I can actually see some things better if I tilt my head back and look through my glasses at a slight angle or through the bottom of the lens. What gives? [more inside]
My eyes have always been a problem. I had a partial retinal tear 20 years ago. I have tons of floaters. I am extremely nearsighted. I have "dry holes" in the back of my eyes from histoplasmosis. All of these things have been stable forever. Today, something new happened. It's in one eye only. It's like there's a black worm with a long tail dancing across my eye. It seems to be fixed in the center of my eye and it's swimming back and forth from that fixed place. What's going on? [more inside]
I had been using Oprah's free 'O board', which was a free dream or vision board. Do you know of any other free ones that are just as good and easy to use?
For the past 6 months or so I’ve been having a problem with double vision after a day of work in front of a computer screen. This is monocular diplopia, that is, double vision that still occurs when one eye is closed (it’s about equal in both eyes). I’ve seen an ophthalmologist who said it appeared to be caused by dry spots on my corneas and the artificial tears he had me tried don’t seem to alleviate the double vision. Has anyone dealt with anything similar? [more inside]
I bought my first pair of eyeglasses recently and they look great, but after about ten days I just can't get used to them. They are sharp when I hold my phone or a book a foot from my face, but not as sharp when something is further away (like my computer screen). These are single-vision glasses so I'm not just looking through the wrong part. [more inside]
Tell me what I need to know about buying eyeglasses for the first time so I ask the right questions and don't buy things I don't need. Cost is not really a factor, though; I'd rather do this right and not skimp (and regret it later). Bonus if you can recommend a specific place to go in Milwaukee. I do not want to order online. [more inside]
I notice that my eyes seem to constantly be focussing/defocussing, almost exactly like a crappy phone camera struggling to focus. I have a mild astigmatism, and just got the prescription updated and new glasses issued. [more inside]
I just had my eye sight tested by an optometrist. He did the standard eye health screening. My eye pressure was "high-normal" and when he looked at my optic nerve, he said that it was 45% "carved out" suggesting that even though my pressure was in the normal range, I might have some progression toward glaucoma. He wants me to have more tests done, including photographs of my optic nerve, to establish a baseline against which my optic nerve could be compared to in the future. I'm fine getting the tests. But should they be done by an optometrist or an ophthalmologist? [more inside]

Lately I've been noticing my vision just seems crappy; I notice my vision just seems "busy"/"shimmering"/slightly noisy. This is particularly noticeable when I'm looking at high contrast things, like computer monitors in a dimmer room. I also see "outlines"/a glow, around contrasting colours, as well as what feels like flickering in some portions of my vision towards the periphery. [more inside]
I've been wearing glasses and/or contacts to correct far-sightedness for most of my life but recently I bit the bullet and switched to bifocals. The has mostly been a great improvement but now I find that basically all the below-the-knee grooming stuff is really difficult in the shower, where I can't really wear my glasses. I feel kind of dumb, but I can't be the only one with this problem. Have you faced this problem? Did you find a workaround? Or is this just another frustrating PITA part of getting older? [more inside]
My new prescription is dramatically different from my old one from just a couple of years ago... does that make sense? [more inside]

I'm a new to eyeglasses as an adult (got my first pair two years ago at age 35). Aside from mild nearsightedness I have healthy eyes so far, but I have a family history of bad eye issues such as retinal detachments. What should I be doing now to maximize my eye health going forward? [more inside]
My 7 year old nephew really wants to be able to take pictures of animals at night. He watches a lot of nature documentaries and sees the night vision video and wants to replicate it. Assume we're not going to spend thousands of dollars but between his saved allowance and Christmas money we might get up to the multi hundred dollar range - is there something that would work for this? Googling and trolling Amazon haven't turned up anything that looks like a great solution. Thanks!
I HATE driving at night. Oncoming moving headlights bother my eyes, and I feel less confident in my depth perception. How do I get better at it? [more inside]
I had an eye exam by an optometrist at a boutique (non-chain) eye glass shop. This store is known for it's unique selection, and I selected an Oakley frame - with lenses ground by Oakley, and an everyday pair with the lenses ground by their usual lab. Unfortunately, my vision is a little bluury in my left eye with both pairs of glasses, and I feel nauseated when I wear them. I've only been able to wear either pair for a max of 20 minutes before I have to remove them due to the nausea and unsettled feeling. [more inside]

Recently, when flying over islands, I've noticed that the waves on the seashore appear to be motionless from cruising altitude. That is, you can see the white foam on the beach but it seems to be frozen in place and not ebbing/returning. Is there a name for this visual effect?
Holding a mug close to my face, there is an interesting effect. It's not like other things and I can't duplicate it with other objects. [more inside]
Will splitting the difference between distance and near pupillary distance make my glasses easier to use? [more inside]
I've worn contacts for over 30 years now but have recently considered getting Lasik. I have heavy astigmatism and have been wearing toric lenses, which work most of the time but still tend to drift making my vision poor at any distance. I signed up for a Lasik seminar, attended and was interested in continuing. I stopped wearing my contacts over two weeks before my preop exam but apparently my eyes still haven't settled to a consistent shape because they couldn't get consistent results when measuring them. I have another exam scheduled in two weeks but I'm beginning to wonder if it's even worth it. Should I just accept defeat or go back and try again?
I have been having increasing problems with my vision over the past few years. I've seen an ophthalmologist, a retina specialist, and had some tests done, but they haven't found anything. Do you have any suggestions for how to proceed? [more inside]
As I search for a new car to replace the old saab it occurs to me that I could use better headlamps to aid the old eyes. At times I feel on the edge of being unsafe when on a two way country road with oncoming headlights (divided highways are ok), a situation that I strive to avoid. I'm looking for personal observations regarding different headlamp types. [more inside]
What compact camera would you recommend for a senior citizen who uses reading glasses and just doesn't have the greatest eyesight overall? Any specific features to look for, especially in terms of the viewfinder?

My sister is in a rehab hospital recovering from a brain injury. She has a lot of time between physio and therapist sessions and she has to entertain herself. Unfortunately she now has limited, blurry vision (legally blind) - she can enlarge text messages and facebook messages but reading a book is too difficult. She has an iPad but is limited to rewatching movies that she is already familiar with as it is otherwise too difficult to see what is happening. She is getting tired of sitting there just listening to audiobooks and I would love to hear any other ideas you might have (including simple apps/games) that could help keep her occupied. Thankyou!

I do a lot of proofreading for work, but it's a struggle compared to proofreading hard copies. I already use f.lux to cut down on eye strain, and browser plugins to make text more readable, but I find I'm still straining to keep my eyes from bouncing all over the place. Help! [more inside]
When I was around 8 years old, I would get headaches if I watched TV for more than an hour or so. My mother took my to the optometrist and I was given an Rx for glasses that were supposed to make my eyes "aline correctly". What is the technical term for the type of vision defect I was suffering from? [more inside]
Does anyone have experience with vision therapy? I have difficulty focusing both eyes at the same time, and I have been told by optometrists that I basically just have to live with this. But I recently read about vision therapy, which seems promising. If you have gone through it, did it work, and was it worth the time and expense? [more inside]
