What does 0.75 reading glasses mean in terms of magnifcation?
Simply put, it means you'll want your reading material about 1.33 meters away from your eyes. The letters will look about as large as they always do at a distance of 1.33 meters, but with the glasses on you'll be able to focus on your reading material comfortably.If you'd rather have your book or screen 1 meter away, use +1 diopter lenses; half a meter away, use +2 diopter lenses; 0.33 meters away, use +3 diopter lenses and so on. The closer you put the reading material, the larger it appears (just like always). Of course your mileage may vary, so use these numbers as a starting point to see what works for you.The general idea is that those of us with so-called "normal" vision (or vision that's been corrected to normal with glasses or contact lenses) are focused on objects a long way away when our eyes are relaxed. By using reading glasses and putting our reading material one focal length in front of the glasses, we make the reading material appear to be a long way away, without changing it's apparent size. The focal length of the lenses in meters is 1 divided by the power in diopters. One might say the purpose of reading glasses isn't to magnify, it's to be able to focus comfortably.Sometimes optics like magnifying glasses and telescope eyepieces are spec'ed in terms of magnifying power. Magnifying power can be calculated as the power of the lens in diopters, divided by 4. The idea here is that someone decided 250 mm is a reasonable value for the closest "normal" people can focus, so they use 4 diopters for the baseline to compare against when considering the apparent size of objects viewed through a magnifying lens.
My daughter got glasses almost a year ago and she is twelve years she can't see perfect in glasses anymore she is nearsighted why is that happening does she need stronger glasses is that normal?
Its normal for a person who is still growing to need new glasses every year, or even sooner. Just as their body is growing their eyes are changing, which makes their vision change to. Because of this a new prescription is needed. Even adults who are not growing will need to get their eyes checked every year in case their eyes have changed.
Why do old people's reading glasses look blurry?
Glasses are optics which are designed specifically for the owner. They correct the focal length of the light projected on the retina on the back wall of the eyeball. If your eyeball is not the same shape of depth as the person who owns the glasses then the image seen through them will appear to be out of focus to you. It is not wise to use anothers glasses since the muscles in your eye will attempt to correct the image and may strain them in doing so.

What type of sunglass lenses must a contact lenses wearer use?
You can wear your normal sunglasses if you want to be careful you can wear something a little bit stronger but you shouldn't have to change anything
Why are normal glasses never a substitute for safety glasses?
Normal glasses are not impact-resistant like safety glasses, so they can easily shatter upon impact and fail to protect the eyes from flying debris or other hazards. Safety glasses are specifically designed and tested to meet safety standards for impact resistance and provide proper eye protection in hazardous environments.
