Eyeglasses have been an essential part nowadays, especially for those people whose job requires them to stare at their computer for long hours. But wearing eyeglasses can be difficult, although it is easier if you find the best lenses for your eyes. Choosing eyeglasses with proper lenses can help provide a clearer focus and more comfortable vision. In addition to vision correction, they also provide a fashion statement. But as with any type of eyewear, lenses need to be replaced on occasion too.
Types of Lenses Materials
If you are using eyewear that comes with the lenses, chances are it will have to be replaced because most of these glasses' lenses cannot last for more than two years. This is why people should replace their lenses at least once every two years.
Eyeglasses that come with lenses are called single-vision eyewear, and they have a one-size-fits-all type of lens. If you have a pair of glasses with the same kind of lenses in both eyes, it may be possible to use one lens for two different prescriptions. But if they are not the same prescription or power, this could lead to eye strain and difficulty focusing on things far away from you because there is a difference in the power between your two eyes.
You may also opt to purchase different types of lenses like bifocal, progressive, or multifocal in order to make your vision correction more comfortable because the glasses can be adjusted to fit your needs. Here are few lists of popular lenses materials you can choose from:
Plastic Lenses
Plastic lenses are made of a plastic polymer called CR-39 (Columbia Resin 39). They are the most cost-effective type of lenses, and they can last for five to ten years. Plastic is often used because it has good durability, strength, optical clarity, and scratch resistance. Because they have no additional coatings or treatments on them, these lenses can be cleaned with just soap and water.
Lightweight Lenses
These are a type of plastic lens that is thinner than regular lenses. They are often used for people who have light sensitivity due to the thickness and weight of the lens.
Glass Lenses
Glass lenses offer exceptional optical clarity and scratch resistance but are more expensive than plastic lenses because they need to be made of higher quality materials. They also have high durability and strength.
FDA Approved Lenses
If you are looking for a lens that can be worn on top of eyeglasses or contact lenses, then FDA-approved glasses may be what you need. These types of glasses allow your eyes to breathe by not blocking them from the air around them as regular contacts do.
Polycarbonate Lenses
If you need glasses for an active lifestyle, polycarbonate lenses may be the best option. They are lightweight and strong to withstand any activity.
Trivex Lenses
Trivex lenses are an excellent alternative for polycarbonate lenses. They are also lightweight and strong and have impact resistance qualities.
High-Index Plastic Lenses
These types of lenses are the thinnest type of lenses. If you have a strong prescription, these may be the best option for you because they are thinner and lighter than other lens options.
Perspex Lenses
If what you need is sunglasses instead of glasses with lenses, then Perspex should be your choice. These types of frames do not require any prescriptions.
Tips: If you care about how your lenses look, then Perspex and polycarbonate are the best options. If what you need is a type that will be durable to withstand any activity, or if it's for sunglasses instead of glasses with lenses, then Trivex may be an option as well. High Index plastic can also be a good choice if you have a strong prescription or want to care for your lenses in any way. In general, the best type of lens will depend on what is most important to you and your lifestyle.
Can I Replace my Lenses and Keep my Frames?
The short answer to that is yes. Eyeglasses are made of plastic, so it's possible to change the lens without replacing the frame if needed. A good rule of thumb is that when a new prescription is needed, it's time to replace the lens. However, if you've had your glasses for a while and need new lenses because of an eye injury or something else that has changed your vision, then yes, the frame can stay.
The decision to replace one's eyeglass lenses does not automatically mean that you have to purchase new frames, as with most optical services such as eye exams, glasses prescriptions, and lens replacements. Replacing glasses frames are expensive, while replacing eyeglass lenses may not cost as much.
Lens Replacement and Care Tips
It is vital that your lens replacement doesn't bubble or have a "foggy" appearance because it could result in poor vision quality. In addition, it's essential to take good care of your eyeglass lenses because it will help them last longer. Here are some tips on how to take care of glasses and lens frames:
1) The first thing you should do is consult your eye care provider about what kind of lens would suit your glasses' needs. They will be able to tell you what the best type of lens is for a specific need and lifestyle, such as sports or outdoor activities.
2) Another thing that can help new eyeglass lenses last longer and stay safer in frames is protective coatings. These thin layers of material give extra protection against wear and tear and damage.
3) Clean the glass frame using a clean cloth or tissue with water, rubbing alcohol, or soap and water mixed together well. Make sure that you dry them with a clean cloth to avoid damaging the frame.
4) Clean the front and back surfaces of your lenses using isopropyl alcohol or a lens cleaner.
5) To prevent any scratches on the lenses, make sure that you put a protective coating (such as UV Protection) onto your new eyeglass lenses before putting them into frames.
It is essential to consult your eye doctor before getting your glasses lens replacement, as with all eyeglass prescriptions. Depending on the type of prescription, it may be possible to order a new pair that can fit into your old frames, but this is not always the case.
The best way to verify what type of eyeglass lenses replacement is suitable for you is by scheduling a visit to your eye doctor. They will be able to tell you what the best type of lens is for a specific need and lifestyle, such as sports or outdoor activities.
