When a person has higher amounts of nearsightedness their eyeglass lenses are thick. This causes minification, which is when images appear smaller than real life-size. People with high amounts of nearsightedness actually see better with contacts because minification does not happen with contact lenses.
Depth Perception – When adjusting to your new lenses, you may have difficulty discerning how far or how close an object is. Those who are nearsighted with a powerful prescription can experience objects looking smaller than before, tricking the brain into thinking they're further away than they actually are.
New Glasses Causing Fishbowl Effect. If you are getting glasses for the first time or you have a substantial change in your prescription, your new pair may take some getting used to. Generally, it should only take a couple of days to adjust to your new glasses, but that adjustment period is sometimes disorienting.
Corrective lenses will cause objects (and print) to appear slightly larger than life. The opposite occurs with glasses for nearsightedness (myopia). They make images appear slightly smaller. This is why the eyes of people who wear glasses appear a bit smaller or larger (to onlookers) when they remove their glasses.
Eye strain: Your eyes need to work harder to focus when wearing new glasses, making them feel tired or strained. Fishbowl effect: Wearing new glasses can lead to a fishbowl effect where images look bent along their edges, making it feel like you're looking through a fishbowl.

“Plus” lenses are for farsightedness, and the more farsighted one is, the stronger the lens. Strong “plus” lenses cause the eyes to appear magnified. Also images seen through the lenses will appear larger than they really are.
Glasses that are too big will feel like they're slipping off of your face and ears. They'll often be too wide for your face, with the lenses extending too far past the sides. If your eyes look a bit too close together (or close to the glasses bridge), that's another signal that your glasses might be too big.
Gradually Increase the Amount of Time You Wear Your Glasses
Because it takes a while for your eyes to adjust to a new prescription, it's not always the best idea to wear glasses all day when you first get them. Instead, try to increase the amount of time you wear them little by little each day.
The usual reason is lens design. The usual culprit being base curve ( front curve) of lenses. This can usually be alleviated with use of aspheric lenses which reduce the curves used and effectively reduce the fishbowl effect. Additionally,some frames which require the use of higher curves must also be avoided.
Is it okay to go back and forth between the two? Answer: If you have two pairs of glasses -- one which is older and one which is newer, and you go back and forth, it may be because they're really meant for two different tasks. And if one works for one task and the other for the other task, you're not harming your eyes.
People with moderate to severe astigmatism definitely require some time for adjusting to glasses with astigmatism. It takes around three days to a couple of weeks to get acquainted with the new glasses as astigmatism glasses feel weird at the first stage.

Astigmatism is a common eye problem that can make your vision blurry or distorted. It happens when your cornea (the clear front layer of your eye) or lens (an inner part of your eye that helps the eye focus) has a different shape than normal. The only way to find out if you have astigmatism is to get an eye exam.
Large frames have a way of making eyes look larger and more expressive. This look has been used by celebrities and others who want to either hide their identities or increase their cool factor.
Do glasses go above eyebrows? Ideally, the top of your glasses should follow your brow line. It's perfectly okay if the frame covers them slightly as large or thick spectacles can often do this. If your eyebrows are below the top of your gasses, your bridge-width may be too wide or the frame may be too large for you.
If the edge of the credit card ends at or near the corner of your eye, your lens fit should be standard size. If the edge of the credit card extends well beyond the corner of your eye, you should get a small size. If the edge of the credit card does not reach the corner of your, then opt for a large size.
