Do I Need Thin Lenses?

When ordering prescription glasses online, one of the most common upgrade options people see is “Thin & Light lenses”.

And naturally, many customers ask:

“Do I actually need thinner lenses?”

The honest answer is: not always.

For some prescriptions, standard lenses can still look excellent. For others, thinner lenses can dramatically improve the appearance, comfort and overall feel of the finished glasses.

At Burghley & Co, we believe choosing lenses should feel straightforward rather than confusing. As a UK Registered Dispensing Optician-led business, we focus on helping customers choose eyewear that genuinely suits their prescription, frame and lifestyle.

What are thin lenses?

Thin lenses are made from higher-index lens materials that bend light more efficiently.

This allows the lenses to often be made:

  • Thinner
  • Lighter
  • More refined cosmetically
  • More comfortable for stronger prescriptions

Common thin lens options include:

  • 1.6 index lenses
  • 1.67 index lenses
  • 1.74 index lenses

Learn more in our guide to understanding lens thickness.

Do stronger prescriptions need thin lenses?

Often, yes.

As prescriptions become stronger, lenses naturally become thicker — particularly around the edges for short-sighted prescriptions.

Thin lenses can help reduce:

  • Visible edge thickness
  • Overall lens weight
  • Bulky appearance
  • Pressure on the nose and ears

For stronger prescriptions, thin lenses can make a very noticeable difference to both comfort and cosmetics.

Do lower prescriptions need thin lenses?

Not necessarily.

For lower prescriptions, standard 1.5 lenses can still look excellent — especially in smaller or thicker acetate frames.

In some cases, customers simply prefer thinner lenses because they:

  • Feel lighter
  • Look more refined
  • Suit certain frame styles better
  • Create a more premium overall finish

So while thin lenses may not always be essential, they can still improve the final result aesthetically.

Frame choice matters just as much

One of the biggest misconceptions is that lens thickness depends purely on prescription.

In reality, frame choice can make a huge difference.

Larger frames generally create thicker lenses because the lens extends further from the optical centre.

Smaller or more balanced frames often naturally reduce thickness.

This is why choosing the right frame matters just as much as choosing the right lens material.

Are thin lenses lighter?

Usually, yes.

Higher-index lenses are often lighter than standard lenses for stronger prescriptions, which can improve all-day comfort significantly.

This can be especially important for:

  • Strong prescriptions
  • Varifocal wearers
  • Larger frames
  • All-day glasses users

Do thin lenses look better?

For many people, yes.

Thin lenses can create:

  • A cleaner profile
  • Reduced edge visibility
  • A more balanced look in designer frames
  • A more refined finish overall

This becomes particularly noticeable in:

  • Metal frames
  • Rimless frames
  • Larger frames
  • Minimal frame styles

Are thin lenses worth it for varifocals?

Often, yes.

Varifocal lenses already contain multiple visual zones, so reducing weight and thickness can improve overall comfort — particularly for stronger prescriptions.

Many customers wearing varifocals prefer thinner lenses because they:

  • Feel lighter on the face
  • Improve balance
  • Create a more premium finish
  • Reduce bulk in larger frames

What is the best thin lens option?

There is no universal “best” lens.

The ideal option depends on:

  • Your prescription strength
  • Your frame size
  • Your prescription type
  • Your cosmetic preferences
  • Your comfort priorities

For many customers:

  • 1.6 is an excellent everyday upgrade.
  • 1.67 suits stronger prescriptions well.
  • 1.74 is often best for very strong prescriptions.

Can thin lenses improve comfort?

Absolutely.

Heavier lenses can sometimes cause:

  • Pressure on the nose
  • Glasses slipping forward
  • General discomfort during long wear

Reducing lens weight can help glasses feel more balanced and wearable throughout the day.
