What Are Single Vision Spectacles?Single vision spectacles carry one corrective power across the entire lens. That single power can correct nearsightedness,farsightedness,or astigmatism — which makes single vision glasses the right choice for most first-time wearers and anyone whose prescription has no ADD value.

How to Confirm Your Prescription Is Single Vision，Pull out your prescription and check three things. First, the SPH(sphere) column — a minus number means distance correction, a plus number means near. Second, the CYL and Axis columns — if they're filled in, your single vision lenses will also correct astigmatism,no upgrade needed. Third, the ADD column — if it's blank, you're single vision. That's the whole test. Every order you place with Aoolia is re-checked against these values by a qualified optician in our lab before your spectacles ship.

Match Your Lens Index to Your Prescription Strength,Thicker prescriptions need thinner lens materials. As a working rule:SPH between 0 and ±2.00 works fine with standard 1.50 index; ±2.00 to ±4.00 looks and feels better in 1.61; ±4.00 to ±6.00 calls for 1.67;beyond ±6.00, choose 1.74 high index so strong single vision lenses stay thin and light in the frame. If you pick an index that doesn't suit your numbers, our opticians flag it before the lenses are cut —that review is included with every pair, not a paid add-on.

Are single vision spectacles the same as single vision glasses?

Yes — 'spectacles' and 'glasses' are the same product. Both refer to frames fitted with lenses that carry one prescription power throughout, as opposed to progressive or bifocal lenses that combine multiple powers.

Can single vision lenses correct astigmatism?

Yes. If your prescription includes CYL and Axis values, they're built into your single vision lenses at no structural change to the lens type. Astigmatism correction doesn't require an upgrade.

What lens index should I choose for a strong prescription?

For SPH above ±4.00, choose 1.67 or 1.74 high index to keep lenses thin and light. If your selected index doesn't match your prescription strength, Aoolia's opticians flag it during pre-ship review rather than cutting an unsuitable lens.

Can I add blue light filtering to single vision spectacles?

Yes. Blue light filtering, photochromic, and standard clear lenses are all available in single vision on every frame in this collection.

How much do single vision spectacles cost at Aoolia?

Frames start at $6.95, with single vision lenses added at checkout based on the index and coatings you choose. Every order includes optician verification before shipping — it isn't a paid extra.
