Many people test new glasses, often ignoring their lifespan. Some wear a pair of glasses for four or five years, or in extreme cases, for ten years without replacement.
Do you think you can use the same glasses indefinitely?
Have you ever observed the state of your lenses?
Maybe when your lenses have become noticeably yellow, you will realize that glasses also have a limited lifespan.
Why do lenses get yellow?
Ordinary anti-blue light lenses: It is normal for resin lenses to show slight yellowing if they are coated, especially for ordinary anti-blue light lenses.
Lens oxidation: However, if the lenses were not initially yellow but become yellowed after wearing them for a while, it is usually due to the oxidation of the resin lenses.
Grease secretion: Some people are more prone to facial oil production. If they don't clean their lenses regularly, the grease can be incorporated into the lenses, causing unavoidable yellowing.
Can yellow lenses still be used？
Every lens has a lifespan, so if yellowing occurs, it's important to determine its cause.
For example, if the lenses have only been used for a short time and are slightly yellowed, with minimal discoloration, you may continue using them for a while. However, if the lenses have developed significant yellowing and have been worn for a long time, blurred vision may occur. This constant blurring of vision may not only lead to eye fatigue but also trigger dry and painful eyes. In such cases, it is advisable to visit a professional eye hospital or optician for a comprehensive eye examination and potentially new lenses.
What should you do if your lenses are yellowing?
This requires paying attention to lens care during daily wear and trying to prevent rapid lens aging. For example, clean lenses properly:
Rinse the surface with cold, clear water, not hot water, as the latter can damage the lens coating.
When there is grease on the lens, use a special cleaning solution; do not use soap or detergent.
Wipe the lens with a microfiber cloth in one direction; do not rub back and forth or use regular clothing to clean it.
Of course, in addition to daily maintenance, you can also choose our BDX4 high-permeability anti-blue light lenses, which are in line with the new national anti-blue standard. At the same time, the lens base is more transparent and non-yellowing!
