    Glasses can also be used in your youth to train an eye to so that you won’t have to wear glasses as an adult.

    I disagree. My vision kept getting worse and I kept needing stronger prescription lenses. Then I went a year without wearing any and following appointment my vision had actually improved dramatically! I have also been spending less time in front of screens and daily focusing on further distances and it's been helping!

    I don’t really like glasses because I got them last year and I’m 15, so it feels weird to put another lens over my eyes when they have been fine my whole life. And since I have wore my glasses my eye sight has definitely gotten worse, so I just avoid wearing my glasses because they hurt my eyes

    I have a question anyone who has idea or can answer my question please reply my question ASAP. My son is eight years old one of his eyes is weaker than the other and he refused to wear his glasses 👓 and this morning I saw him walking differently one of his legs especially in the ankle area looks weak and he said he’s feeling little pain in the thigh area he’s walking different. Can weak eye 👁 cause imbalance walking?

    He didn't mention Astigmatism.This involves a defect in the eye lens,causing rays from a point to fail to meet in a focal point resulting in a blurred,and imperfect image.Thus,Astigmatism is in contrast to Myopia(Nearsightedness),and.Hyperopia( Farsighredness),which basically just involves defects in the length of the eyeball rather than its, lens.

    I had astigmatism as a child and wore glasses from the time I was 5 till I was 15. My eyesight got better to the point where I didn't have to wear glasses anymore. But now that I'm over 50, I'm developing farsightedness and have to wear reading glasses for close-up stuff like reading and computer work. Argh.

    What's stupid is optometrists only prescribe glasses that make you focus 6m away. Once you can see the sign at 6m sharply, they stop.
    For some people, they don't really see much sharper at the horizon if they focus on the horizon rather than 6m away because their retina doesn't have a high enough resolution to perceive the difference. I however have 2.0 sight meaning I have twice as sharp vision as what's deemed "perfect" vision. So when I got a prescription of -0.5 which let me read the smallest letters on the board 6m away, I noticed my vision was really blurry when viewing things more than about 10m away.

Before I began getting it, my eye-sight was not clear and also my eyes were very dry. The improvements revealed only after 14 days of usage..

    what about the angle? the focus center of the glasses is fixed, while the eyes dinamically change this angle to focus at objects far away or close by.

  • qdllc
    qdllc 2 месяца назад

    There are eye exercises that can correct vision problems. What makes many people’s vision worse is not using their vision on different things throughout the day. If you look at a book or monitor for hours at a time, it weakens your eye muscles which then makes it harder to properly focus on distant objects.
    It’s important to take breaks to let your eyes rest from work and focus on items at varying distances. Not doing this actually aggravates vision issues.

    I hate it, i rather be unable to see anything than wear a thing that makes me weaker. If you need to suffer some kind of stress like, being hit by a ball, run suddenly, fight against someone or something else, the glasses are definitely a disadvantage. I like sports and action, the only glasses I want to wear are the protective ones, when its necessary, maybe swimming glasses when im swimming at night, to avoid accidents. And glasses can make you look like a nerd.

My vision has continued to get worse and every year I need stronger glasses. My vision is now 20/120. My sister's vision is 20/40. I blame hours of looking at a computer monitor with glasses while my sister didn't.

By then my lenses where a quarter of an inch thick (with feather weighs) and I had bifocals since I was 14. I can’t get grams that are not plastic because my lenses will fall out otherwise.
