The replacement cycle of glasses for adults
Unlike children and teenagers, the degree of glasses for adults is usually more stable. However, they still need to have regular medical optometry to ensure the accuracy of their glasses. It is recommended that adults change their glasses every 1.5 to 2 years to maintain good eyesight and eye health. At the same time, if yellowing of the lenses is found, they should also be replaced in a timely manner. After long-term use, lenses may undergo oxidation, leading to lens aging and affecting clarity and light transmittance.
As the usage time of the lenses increases, wear and tear is inevitable. This kind of wear and tear can significantly reduce the optical correction performance of the lenses, causing blurred vision. In severe cases, it may even lead to a series of visual fatigue symptoms, such as eye pain and headache, thereby damaging vision health. Therefore, once any wear and tear on the lenses is detected, they should be replaced promptly to ensure a good visual experience and eye health.
As the usage time of glasses increases, the frames may gradually deform and become crooked. At the same time, problems such as loose temples and uneven nose frames may also occur. These problems can cause the optical center of the lens to shift, thereby having adverse effects on eye health. Therefore, regularly checking and adjusting the condition of your glasses to ensure they remain fit and comfortable is an important part of maintaining eye health.
When the degree of the glasses does not match the actual degree of myopia, the wearer may feel a headache and even need to squint or push up the glasses to see objects clearly. This will increase eye fatigue and further lead to an increase in the degree of myopia. Therefore, myopic patients should regularly check the matching degree between their eyes and glasses to ensure that the degree of their glasses always matches the actual degree of myopia. It is recommended to have an eye and glasses examination every half to two years to detect problems in time and adjust the frames or get new glasses.
