Apart from getting the right frames for your prescription eyeglasses, it’s a must to select the right lens type too. They are more important and cost more than frames. When the various types of lens materials and coatings are put into consideration, discovering the lens that meet your eye correction needs may be a daunting task. The truth is that many people spend more money on eyeglasses when it is time to replace the old ones and still end up with a pair that worsens their eye conditions. Whether you require a single vision or multi vision lenses, this guide can go a long way in understanding the popular types of lenses that are available.
· Polycarbonate lens
Several decades ago, eyeglasses were made from glass materials which get broken easily and are heavier. Most of today’s lenses are designed from high-tech plastics. Generally, polycarbonate lenses are impact-resistant. They are also lighter than the regular plastic lenses and are very durable. People that participate in sporting activities or work in an environment that requires safety googles find it a great choice. In addition, it’s popularly used in the manufacturing of children’s eyewear. Polycarbonate lens usually comes with a 100% built-in UV protection.
· High index lens
Lenses become heavier and thicker as an individual’s prescription gets stronger. Due to the fact that high index lenses have a higher index of refraction, they are relatively lighter and thinner than CR-39 lenses. These types of lenses works best for a very strong prescription. Even though high index lenses are lightweight in appearance, they are made from materials that are shatter proof.
· Bifocal lens
In case you have more than one vision problem, wearing a bifocal lens eliminates the need to carry more than one pair of glasses around. Bifocal lenses are very powerful and works by combining distance vision and near vision prescription into a single lens. They are the most popular type of multifocal eyeglasses and are usually prescribed for age-related eye problems. The other type is the trifocal lens.
· Progressive lens
Just like polycarbonate lenses, progressive lenses are impact-resistant. They are usually manufactured with polycarbonate, CR-39 and high-index lenses. It is important to note that they are more expensive than bifocal lenses. The wearer can enjoy the benefits of bifocal lenses and use their eyeglasses without horizontal lines in their lenses. Using progressive lenses provide an unnoticeable transition in lens strength.
Once you’ve discovered the appropriate lens for your eyes, endeavor to get in touch with your eye doctor and request for an up-to-date eyeglass prescription. They can also offer insights on the best eyeglass lenses that are available.
