Tips For Adaptation Issues
Getting used to new glasses
It usually takes several days to get used to new glasses. The amount of light that enters your new lenses (light transmittance) will be a lot higher than your old ones. So you may feel that they are a lot brighter to look through.
Getting used to a new prescription
Some customers may feel that a new prescription is too strong, and that it can almost feel a bit painful. This is normal with new prescriptions! Usually, it takes about one week to adapt to a new prescription. If you are still having difficulty, after a week or even a few days, you should ask your eye doctor to recheck your prescription and ensure it is accurate. In the meantime, you can use your previous glasses if you feel comfortable doing so.
Issues caused by changing your frame shape
When changing from square to round frames, or small to big frames (in which the lens tends to be thicker), some customers may feel a little dizzy, as one might with a new prescription. It will take about a week to get used to a different frame shape and size. If you still feel dizzy, after that period, you might consider returning to your previous frame style and shape.
Issues caused by discordance of prescription and lens index.
It is important to balance your prescription strength and lens index. If you have a strong prescription, choose a high index lens; a low index lens will be thick, which means a larger blind zone, which leads to more distortion in vision. If you have lower-strength prescription, choose a low index lens; a high index lens will reduce the light transmittance and increase chromatic aberration, which leads to a decrease in visual clarity.
Issues caused by out-of-date prescription
If your current prescription glasses are blurring your vision or causing dizziness, that prescription may be out of date. It is strongly recommended that you visit your eye doctor to find out if your prescription needs to be changed.
Issues caused by the spherical lenses
Generally speaking, the spherical lens is thick and the image coming through it will be distorted. An aspherical lens, with its wide vision, results in clearer and more natural image. The same prescription and index, with a thinner aspherical lens, is lighter and more comfortable for wearers. Wearers will not feel tired after wearing aspherical lens for a long time.
Issues caused by glare
Anti-reflective coating is a very important part of your prescription glasses. If you don't choose anti-reflective coating, you may feel the lens produce a lot of glare. Anti-reflective lenses are great for photographs, as they reduce reflections. They also allow people to better see your eyes. Be sure to choose the anit-reflective coating when you order your glasses.
Issues caused by adjustable nose pads
The position and direction of adjustable nose pads will affect the distance between your eyes and your lenses. If you are nearsighted, and the distance is too short, you may feel the prescription is too strong and causes some pain in the eyes. You could try to adjust the nose pads by forcing them inwards toward each other; this will increase the distance. If the distance is too far, you can adjust the nosepads outward, away from each other, to decrease the distance. If you are farsighted, simply reverse the nearsighted instructions.
Issues caused by blue light blocking lenses Blue light blocking lenses are made from a light yellow/brown material that blocks the blue light that radiates from electronic devices. The yellow/brown will make your vision darker and reduce the light transmittance. Blue light blocking lenses also have a blue/purple coating, which is more reflective compared to regular glasses. You may feel some glare and discomfort when first using them, because the blocking power is so strong, but that will disappear after a few days. Since the sun also transmits blue light, these glasses are perfect for everyday use, as well, especially for those who spend a lot of time looking at a computer screen or other types of screens.
An accurate prescription doesn't always mean comfortable glasses.
To process a pair of glasses, in addition to the accuracy, we still need to think about the balance of your eyes' diopters, as well as comfort and other factors. But there can be times when a prescription only attempts to show the condition of your eyes, without taking into account the fact that you want to use that information in making a pair of glasses. If you find you are experiencing headache or dizziness while wearing eyeglasses that have your exact precription in a proper frame, you may need to ask your doctor to adjust your prescription and make it suitable for eyeglasses.
Getting used to progressive lenses
It is important that you give yourself time when adjusting to progressive lenses. The process can take as long as several weeks. If you still feel uncomfortable after several weeks, you might consider switching to bifocal lenses or separate glasses for reading and distance.
