When to change your glasses? This is a classic question that every eyeglass user asks. Many people simply do not know the basics of replacing glasses so that instead of looking cool; they look silly after wearing their new glasses! The classic question actually refers to how often we should replace our old glasses with new ones. Of course this is very relative, depending on the circumstances of each person who is certainly different from each other. This article was created with the aim of guiding everyone who has no idea of what they should do when replacing their old glasses. If you are one of them then you are now on the right page. You will be able to know what need to do when you’re going to replace lenses in glasses.
How often do you have to change your glasses? In many cases it is not considered necessary to change glasses until the lens is damaged or the frame is damaged. However, it is very important to keep in mind that the glasses are used to compensate for defects of vision and, therefore, it will be very important that the lenses are adapted to the evolution of these defects in order to compensate them. The main reason to change glasses is that the graduation of the lenses is no longer optimized to compensate for the vision defect. But there are other factors that can lead to a person considering changing glasses.
To know when to change the glasses you must take into account some important factors below:
The general recommendation is that people who wear glasses should go to the ophthalmologist at least once a year in order to be able to make the appropriate tests to see if their graduation has changed or not. Likewise, anyone who, using their current glasses, feels dizzy, headaches or blurred vision must pass by the optician or ophthalmologist to perform a vision check. Since this is usually a fairly clear symptom, you can make sure that your current glasses are no longer optimized for graduation.
We can say that it will only be necessary to change our glasses when there is an increase of the deterioration of the visual acuity. It is often said that values tend to increase progressively in 0.25 diopter sections. At the time that a 0.5 diopter increase occurs over the current graduation of the glasses, it is the right time for us to change our lenses for new ones with the updated graduation. If the increase is even greater, the need for changing glasses is much more urgent. In children and adolescents this diopter increase is linked to growth and will continue to develop into adulthood. So you have to calculate that at this stage you will at least need to change your glasses every two years. In presbyopia, impairment during the first few years may be much slower. As the age increases, the ocular defect increases. The first reading glasses can be worth for 5 or 10 years, but the second pair will last about 2 years.
Fashion and trends
People who like to follow the fashion have a little difficult. In fact, the trends are changing and new designs are imposed day by day. The fashion lover will have to assess when it is time to change the glasses to be up to date. You are advised to not only choose your new glasses frame based on the look and price. You should choose the glasses according to your face shape. This is an important part because the quality of your appearance (after wearing glasses) is largely determined by how much your glasses influence in “fixing” the symmetrical sides.

Loss or breakage
Unfortunately, accidents happen and the glasses fall and break. Many times these accidents happen to people who have been wearing spectacles for a short time and have not yet become accustomed to the sensation of wearing them all day. People who are accustomed to wearing glasses develop an “instinct” that makes them more accustomed to dealing with them, not making sudden movements. But there is always be an accident.
Sometimes you need to change the frame of your glasses too
One thing that distinguishes between one product to another is usually in term of frames used. The frames are available in a variety of unique and funny forms. Some of these frame options can make your display cooler, or look funnier.
The selection starts to base on the shape as well as the color. But there are other parts that should be your consideration, i.e. in term of material as it greatly determine the quality of your eyeglasses. Here at least some choices of frame material that you should know:
1. Plastic material.
This material has the cheapest price, its special characteristics are clear and light, so that when used for a long time, it doesn’t cause pain in the ear or mid-eye or nose. Many people use plastic-based frames because the frames are comfortable to wear. But you need to know that plastic’s weakness is that it’s very easy to break, especially if it’s already trampled. If so, you need to replace it with a new one because it can’t be repaired again.
2. Aluminum material
It has more resistance when compared with plastic. Its weight is also still relatively light. Paints attached to the material would last very long, although often exposed to sweat. Some aluminum-based frames are equipped with shock spring, keeping them safe from impact.
- Titanium material
The titanium-based frames are generally more common in vintage models. Its weight is very light, even lighter than the plastic.
- Metal material
The metal-based frames are the most powerful ones but those who have an allergy to iron should not use the frames.
