Which Type of Glasses Lens is best for Strong Prescriptions?
What are the high prescription glasses frames?High Prescription Glasses are ideal for you. These eyeglasses are relatively thinner and lighter. Most doctors recommend these types of glasses frames if you have a high prescription for eyeglasses for astigmatism, nearsightedness, and farsightedness. However, it is important to know that the majority of people with nearsightedness wear these types of frames.
High prescription glasses have the ability to effectively bend the light. These glasses have thinner edges than lenses along with the same prescription power, which is made of a conventional and light plastic material.
High-Index LensGlasses with a high-index lens provide a comfortable experience. Lighter and thinner, high-index lenses are a great choice for wearers who are well-aware of both comfort and appearance.
It is important to know that lenses for myopic correction are usually thinner at the center and thicker at the edges. Similarly, you must know that strong prescriptions generally require thicker lens edges.
Today, rimless glasses and semi-rimless eyeglasses frames are prevalent. The convention glass or plastic lenses with thick edges are more obvious that can detract from the appearance of the eyeglass.
In addition, doctors usually determine the prescription of a lens by the amount of light refraction needed by the myopic eyes. When your doctor gives you higher or stronger prescriptions, then it is important that the lens bend more and more light in order to provide clear vision.
For example, if you have a prescription of -5.0, the lens will need for light refraction. On the other hand, if you have -2.0 prescription, the lens won’t need more light refraction as compared to -5.0.
Similarly, higher minus lenses require lens edges that are thicker enough. Myopia progresses more with the growing age. So, this means your lens edge will likewise grow in thickness.
High-index material is capable of bending more light in an efficient way, which makes myopic lenses have thinner edges as compared to conventional plastic lenses. As a result, efficiency reduces high-index lens materials.
At the same time, it also ensures myopic correction. So, thinner lenses not only decrease the overall weight of lenses but also have aspheric lens designs that make these lenses flatter to enhance appearance.
The application of an anti-reflective coating may also improve or enhance the wearer appearance and visual aid through high-index lenses. While conventional lenses bend about 7-8 percent of the light that enters your eyes, the regular high-index lens can bend 50 percent more light.
So, when you apply high-index lenses with anti-reflective coating, they can transmit 98.5 percent of the light. Thus, it reduces light reflection from the surface of the lens.
