Are you in need of new lenses for your glasses? Most optometrists will recommend that you get new lenses every 1 to 3 years if needed. However, if you are experiencing vision changes, headaches, or other side effects from the old prescription, you may need to get new lenses sooner. If you are ready to get the best lenses for your glasses, there are some things that you should look into.
What Kind is Your Prescription?
If you are looking for the different lenses that you may need, you may want to know about the best prescription lens types. You may need bifocals, progressive, or single-vision lenses.
Single Vision Lenses
The most commonly prescribed lenses are single vision lenses. They are prescribed for vision correction for either distance or reading. Single vision lenses have only one vision field throughout the lens. They improve your vision whether you are nearsighted or farsighted. You could also use these lenses to help you read better, as well.
There are 2 viewing areas in bifocal lenses which is distinguished with a visible line on the lenses. The bigger viewing area is for seeing better when reading. Even though this is a bigger viewing area, it is the smaller part of the lenses. If you are new to wearing bifocal lenses it might take time for you to get used to wearing them. This is because you need to learn how to become accustomed to moving your eyes from the area of the glasses that is for distances to the area that is for reading and vice versa. In order to get used to your bifocal lenses, you should wear them often. In time, your eyes will learn to adjust to the different viewing areas.
You may also need progressive lenses. These have no line on them. However, they are still considered multi-focals. The progression is seamless. You will still get improved sight for both near vision and intermediate vision. These lenses work by moving your eyes from one area on the lens to another area. WIth progressive lenses, you should be able to see things better at almost any distance.
You might have picked a pair of glasses because you like the way they look but don’t really need any vision correction. It is important to know that most frames come with non-prescription demo lenses that are not optical quality. These can harm your eyes. Switch those out for optical quality no-power lenses.
Best Options for Lens Material
When looking for the best lenses for your glasses, the material does make a difference. Some of the best lens materials include high index 1.67, high index 1.74, plastic CR 39, and
polycarbonate. Your choice in lens material will depend on the strength of your prescription.
Plastic CR 39
One of the basic lenses is the plastic CR 39 lenses. These are made with plastic polymer. The refraction index for these lenses is 1.498, which means they cannot be used for correcting high powers. Plastic CR-39 lenses have very low impact resistance and they can be easily scratched. They cannot be used for semi-rimless and rimless frames.
Do you want lighter, thinner, and stronger lenses? If so, the polycarbonate lenses would be your ideal choice. The polycarbonate lenses are impact-resistant, shatter-proof, and offer complete protection from UV rays. They are great for both kids and adults. They are also ideal for most regular-ranged prescriptions and are widely used. They can be fit into rimless frames.
High Index 1.67
When compared to the polycarbonate lenses, the high index 1.67 lenses are 20% thinner, and 30% thinner than plastic lenses. If you have a high prescription, the high index 1.67 lenses are recommended. These will have less weight and reduced thickness around the edges.
High Index 1.74
If you want the flattest, thinnest, and most attractive lenses, you will want to go with the high index 1.74 lenses. These are extremely thin. When compared to plastic, the high index 1.74 lenses are 50% thinner. When compared to high index 1.67 lenses, these lenses are 5% thinner. The 1.74 high index lenses are most ideal for very high prescriptions
Choosing the Lens Options
Depending on your lifestyle, you can look for the perfect lens options.

Clear lenses can be tinted to different levels to make them darker according to your preference. You can also get your lenses tinted in various colors and gradients from yellow to the more traditional gray. However, tinted lenses do not protect you from the harmful effects of UV light.
