How Long Does It Take to Get Used to New Glasses?
Most people are excited when they get a new pair of glasses for the first time. But sometimes there is an adjustment period before your vision is fully comfortable. So, how long does it take to get used to new glasses?
In most cases, it takes only a few days to adjust to a new pair of glasses. When you are adjusting to your new glasses, you might experience some symptoms such as mild dizziness, blurry vision, or eye strain. This would be a normal situation. These symptoms are common with new glasses and typically last only a few days.
Even though the new glasses come with the same prescription, different frames or lenses can alter your vision until you get used to the new frame style, frame material or lens type.
Besides, other factors will affect the adjustment time, such as the complexity of your prescription, the type of lens, and so on.
How long does it take to adjust to new glasses? It usually takes a few days. However, if you experience eye strain, distorted vision, and especially headaches for a few weeks, you had better contact the eye doctor or the optician. They will check your eyeglass and the prescription.
Commercial pure titanium eyeglass frame
Commercial pure titanium eyeglass frame gives people a professional, handsome, rigorous attitude. The commercially pure titanium eyeglass frame is generally square, with a simple design. And the style is more versatile, making people a cool and handsome feeling. It is men's preferred choice! And for the display of their professional image, they play a great role!
The Benefits of Glasses Without Prescription
From the above part, you have found some basic information about glasses without prescription. In this section, we will list some benefits of plain glasses.
The non-prescription glasses are inexpensive, and they are widely available in a selection of styles and shapes. In addition, non-prescription glasses can be easily replaced as fashion changes.
Meanwhile, everything has two different sides. So, there are also some negative voices of glasses without prescription.
Features of Beta titanium glasses frame
Beta titanium has better strength, fatigue resistance, and environmental corrosion resistance than pure titanium and other titanium alloys. The shape plasticity is very good, which can be made into wire and sheet, more lightweight. They are used to make glasses and can get more shapes and styles. It's the material for a new generation of glasses. Customers with higher requirements for style and weight can completely choose beta-titanium glasses. Because β titanium processing technology is higher than pure titanium, usually only large factories and brands will produce, and the price is higher than pure titanium glasses.
Titanium alloy
The definition of titanium alloy is relatively broad. As long as it contains titanium material, it can be called titanium alloy. Therefore, the quality and grade of titanium alloy glasses frames are uneven, and the component of titanium alloy has a direct impact on the price of titanium alloy glasses. Titanium alloy glasses are made not to reduce the cost, but to improve the application performance of the material.
Testing of aspheric lens
The optical axis of the optical center just overlaps with the visual axis of the eye, which is the most ideal state. Because the light from the edge cannot form a focus on the optical axis, when the optical axis does not overlap with the visual axis (the difference is greater than 2mm), such unclear and scattered imaging results will occur. When choosing frames and aspheric lenses, you need to ensure that they fit correctly, to achieve the best visual and decorative effects. Simply put, due to the special design of the lens, we found through a calculation that the optical center should move down 1mm higher than the pupil for every 2° increase in front inclination angle. Otherwise, the wrong pupil height will cause the lens to look like astigmatism, and cause discomfort. For glasses with aspheric lenses, there must be an inclination angle after wearing. The specific angle varies from person to person.
Glasses should not have serious color differences.
Children's eyes are not fully developed, and the eyeball is still growing slowly, at this time it is best not to wear such blue light glasses with the serious color difference. If you always see things with color differences, it will cause eye discomfort, resulting in increased myopia, but the opposite. The big color difference will cause low light transmittance, affecting child macula development. In the case of long-term distortion and discoloration, visual physiology and psychology will be affected.
Blue light glasses for children have special lenses that block some light waves, which may help protect children's growing eyes from digital eye strain. Blue light lenses sometimes have a slight yellow tint. You can buy prescription or non-prescription glasses with child-size frames and lenses that filter blue light. They don't filter out all the blue light, but they can reduce your child's exposure to blue-violet light by 80 percent or more.
