Thinnest Lenses for High Prescription - What Are My Options?
Traditionally, people that require a high prescription have had to put up with thick, unappealing lenses that protrude from their face and limit their frame options. People want to acquire the most aesthetic look for their glasses and therefore many wonder what are the thinnest lenses for high prescription available.
Thick lenses come with many disadvantages which makes it understandable that people seek extra thin glasses for lenses. Disadvantages include the actual thickness of the lens. Many stylish eyeglasses now come with a minimal look and employ manufacturing techniques that let them achieve a far thinner and minimal frame style. Thick lenses stick out from the glasses frame and ruin the aesthetic intention of the frames. Thick lenses also come with the burden of added weight which not only leads to discomfort over the course of the day but also increases the risk of your glasses slipping off your face and getting damaged.
What are the thinnest lenses for high prescription glasses?
Thanks to the development of high-index lenses, manufacturers are able to provide far slimmer eyewear lenses than in the past. High-index lenses refract light better than standard glass or plastic due to the lens having a higher index of refraction. As a result of this increased efficiency in refraction, high-index lenses are thinner. Using this logic, the higher the index of the lens, the thinner it will be. If you are accustomed to a strong prescription in standard plastic, then making the change could have a big effect on the thickness of your lenses. While even the thinnest lens cannot fully hide the thickness of a high prescription lens 100%, it will drastically reduce how much it is seen.
If you are in search of the thinnest lenses for high prescription glasses, look no further than high index lenses. These types of lenses are available in various indexes, which relates also to their thickness. Index lens options start out at a measurement of 1.50, known as a standard index. They then come in 1.61, 1.67, and 1.74.

What are 1.74 high index lenses?
1.74 index lenses are the thinnest lenses for high prescription glasses available, and they allow even the highest prescriptions possible. They are an ideal match for people whose prescriptions are on the stronger side and who don't like the limited options of thick lenses. These super thin eyeglass lenses are also a perfect choice for people who find that normal lenses distort their eyes. 1.74 index lenses are 5% thinner than the next best option of 1.67 and they are up to a staggering 50% thinner than average plastic lenses.
You might be wondering to yourself how high index lenses work and what the technology behind them is. Well, the thin profile is thanks to the flatter curve that is utilized compared to normal, lower index lenses, which gives it a greatly slimmer profile than its lower index counterpart. Using a flatter curve, however, can lead to peripheral distortion. This is counteracted by the integration of aspheric lens technology, which eliminates spherical aberration.
Are 1.74 lenses worth it?
1.74 index lenses and all the expert technology incorporated into them comes at a higher cost than lenses that use older technology and present lesser qualities. So are they really worth it? It depends on what features of lenses appeal to you, but being the thinnest lenses for prescription glasses around, many people find them a far superior choice. Here are the reasons why:
• Weight. 1.74 index lenses can be more than 25% lighter than normal plastic lenses and more than 50% lighter than glass lenses.
• Aesthetic. As mentioned before, these lenses can be used in more frames and styles, so you won't have to compromise on your look to get the corrective aid that you need.
• Resistance. High index lenses have a higher resistance to scratches than standard plastic meaning you can dodge the hassle of distracting marks in your field of vision. Not only annoying but also potentially damaging to your eyes, causing eye strain and fatigue.
• No yellowing. Due to the fact that standard lenses do not have UV protection already, they need an extra coating to provide this protection. This can cause yellowing of the lenses. 1.74 index lenses are not only the thinnest high-index lenses available, but they also have up to 100% UV protection built-in, so there is no need for the additional coating, and the yellowing issue is eliminated.
• UV protection. As mentioned above, high index lenses have up to 100% UV protection and so you can be at peace with the knowledge that your eyes are shielded from the harmful effects of the sun’s UV rays.
