Thin Lenses
A keen vision needs to know what fits in the frame for a clear vision.
What are thin lenses?
As the name suggests, thin lenses are high-index lenses which allow a higher prescription to be packaged in comparatively thinner lenses. The index of a lens refers to how much light it refracts.
Thin lenses are not only lighter, more comfortable and stylish, they are also stronger. That’s why they are recommended for rimless glasses, where strength is of particular importance.
Super Ultra Thin lens
Ultra-thin lenses have an index of 1.74 and are around 45% thinner than basic lenses.
Suitable for the powers +/- 10
Why thin lenses?
There are a lot of advantages when you go for thin lenses
Lighter
Comfort and ease with thin lenses
Thin lenses are lighter and more comfortable to wear. They ensure that your glasses do not get heavier even with higher or more complex prescriptions. The reduced weight and added comfort becomes very helpful for those who wear glasses all day long.
Variety
Compatible with a wider range of frames
Because of their narrow shape and slimmer edges, they can be glazed into a wide variety of glasses. There’s a good, noticeable difference between thin and standard lenses and in most cases thin lenses do not stick out of the frame.

In simple terms, if you have a combined power above +/- 3 you should consider going for thin lenses, if it is above +/- 6 then go for ultra-thin lenses, and if it’s above +/- 8 then go for super ultra-thin lenses for ideal glazing and perfect quality lenses.

Place OrderChoosing The Thinnest Lenses for High Prescription Eyeglasses
Ultra-thin glasses lenses are a true blessing for individuals with high prescriptions. Conventional lenses tend to become thicker as the prescription strength increases, impacting the aesthetics of the glasses. For those who value fashion, choosing the thinnest lenses for glasses is essential to ensure a stylish appearance. Moreover, these ultra-thin lenses offer added comfort due to their lightweight design, allowing you to wear them throughout the day without any discomfort. You can select the thinnest lenses for high prescriptions during the checkout process, tailored to your specific power.
How do high-index lenses work?
You may already know that we see things because of the light entering our eyes. Vision correction is needed when our eye's lens system doesn't function perfectly, making it difficult to focus images on the retina (think of the retina as a cinema screen where images are projected). This misalignment leads to blurred vision.
Prescription lenses work by refracting (bending) light in a way that shifts the focal point to the correct position, allowing us to see clearly. The stronger the prescription, the more refraction is needed. With standard lenses, this often results in thicker lenses. However, high-index lenses are designed to bend light more efficiently, meaning they require less material even for higher prescriptions, resulting in thinner, lighter lenses.
FAQs
How do High-index Lenses Work?
The index of lenses refers to the way a piece of lens refracts light. In simple words, higher index lenses allow higher prescriptions to be packaged in a thinner piece of lens. You can choose between Basic (1.5 index), Thin (1.6 index), Ultra Thin (1.67 index) and Super Ultra Thin (1.74 index) lenses.
Can thick lenses be thinned?
A particular pair of lenses cannot be thinned. Instead, you will have to go for new high-index lenses.
Do I need thin lenses?
The lens thickness which you need depends on your prescription and the type of frames. In the case of acetate frames, you should consider going for thin lenses (1.6 index) if your prescription is +/- 3 or above. Since metal frames are thinner, they might require thin lenses when your prescription is +/- 2.5 or above. Ultra Thin lenses (1.67) are required if you have a prescription of +/- 6 or above. Similarly, you can go with Super Ultra Thin lenses if your prescription is +/- 8 or above.
Are thin lenses better?
Thin lenses are better in many ways as it is lighter, more comfortable, and aesthetically pleasing to look at. However, it depends on the kind of frame you’ve chosen and the strength of your prescription. You can look at the table above for a better understanding.
Can varifocal lenses be made thinner after purchase?
No lenses including varifocals can be made thinner once they are already cut and glazed. The thickness of lenses depends on the index of the material used - the higher the index, the thinner the lenses. Please refer to questions 1 and 2 for more information!
Can you have thin and light lenses with bifocals?
Yes! You can have thin lenses with any kind of prescription - single vision, bifocals or varifocals.
Do thin lenses cause light sensitivity?
Thin lenses have no association with light sensitivity! If you have been facing light sensitivity, consider going for tinted or photochromic glasses.
How much difference will ultra-thin lenses in glasses make?
Our thin lenses are approximately 20% thinner than basic lenses. Comparatively, Ultra-thin lenses are around 30% thinner.
Are ultra-thin lenses a rip-off?
Whether you need ultra-thin lenses or not depends totally on your prescription and frames. For example, if you have a prescription of just +/- 1, you don’t need ultra-thin lenses at all! If you have a higher prescription like +/- 4 and have opted for thin, sleek metal frames, you might need ultra-thin lenses so that they don’t stick out. For more information, please consult your optometrist!
