Single Vision Spectacles

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.
