48 years old, female, OCA! probably OCA!a.
Have worn glasses /contacts since I was two years old. Finally was able to get my script in contacts at age 23 and haven't looked back!
Do they help? Hmmm.... That is hard to explain! I was always tole that I needed glasses, that I had to wear them all the time, and was made to put them on in the morning and take them off at night. I was a very compliant child on almost all fronts, so I did what I was told! I never questioned the glasses, per se. However, by the time I was about nine or ten I started asking for glasses without the tint in them--I don't remember what color it was--it might have been an amber or pinkish tint. Everyone insisted I needed it for the light and glare, but it didn't do a thing for me. I finally got them to lighten it a little, but I think I was an adult before I was allowed the choice.
Do they help? Do I get an additional line on the eye chart with them? No. It is just clearer, and I can maybe tell how many letters are on the next line on a good day. They sharpen things, maybe magnify somewhat, that is about it. I notice that the correction seems to help my weaker eye more, but it is still weaker. I think it has more astigmatism.
There are days when I am not going to work or whatever that I don't wear my contacts for part or all of the day. I don't know why. I guess I don't really need them to do what I do around the house. Right now, I haven't put my contacts in yet, but I am wearing my reading glasses, which are just magnification power that I usually wear over my contacts. I would be able to read what I am writing a lot better with the contacts, but I am not really having a problem. For long term close work, I do need the contacts and glasses. I guess after so many years of wearing them I have become dependent on them and it is automatic. It is when I am asked to analyze what they do for me that I see it may not be as much as some might think!
My best vision is measured at 20/200, corrected, thus, as you know, legally blind.
I do believe that for some of us, the glasses really don't help that much and the difference isn't worth the effort. It may be that your son, at age 4, has had his vision mature enough that the glasses don't really help like they used to. I kind of remember that feeling. He may see that he needs them more for close work when he gets to school, he may not.
I strongly advise all parents and eye professionals to listen to their childrens 'complaints' about their eye correction, sunglasses, low vision aids, etc. We may all have albinism in common, but we are all unique. There is no one right answer, and any professional who tells me there is--like 'persons with albinism MUST wear sunglasses, have tinted glasses, must have an amber tint--it is the best, can't ever wear contacts, etc., I will promptly stop seeing them. There are multiple solutions, and for some the best may well be no glasses/contacts at all.
OK, off of my soap box. It may be that your son's glasses no longer do what they once did for him as he has learned 'how' to sse his surroundings and what things actually look like. Vision is so much more than just our 'visual acuity'. I would investigate further with the Dr., but I would also listen to your son, as I doubt that his not wanting to wear his glasses has any social origin at his age!
Let us know!
