UV absorption
The lens should block 100% of UV or be labeled as absorbing UV up to 400 nm. Darkness alone does not tell you this.
AAOEyeglasses and Optical · Sunwear
Sunglasses and Polarized Lenses Prescription sunwear as a second pair patients use.
Sunglasses protect against ultraviolet exposure and make bright days more comfortable. For an optical, prescription and polarized sunwear is a natural second-pair conversation that starts from eye health rather than fashion alone.

How sun lenses work
UV blocking, tint and polarization are separate jobs
Patients often assume a dark or polarized lens is automatically protective. Each property does something different, and the AAO stresses that UV protection is the one to check first.
Tint and color
Tint reduces brightness. Gray keeps colors natural, while brown or rose adds contrast that golfers and baseball players often like. Color does not add UV protection.
AAOPolarization
Glare off water and roads is partly polarized. A polarizing filter blocks that component, which is why polarized lenses cut surface glare.
HyperPhysicsCoverage
Larger and wraparound frames block more light from the sides and above.
AAOWhere the sunwear comes from
Plano sunglass brands are concentrated in a few eyewear groups, while Rx sun lenses come from the major lens makers.
- Plano brands from the large eyewear groups
- Rx sun lenses from your lens supplier
- Light-adaptive as a sun alternative

Eyewear groups
EssilorLuxottica (Ray-Ban, Oakley), Kering Eyewear (Maui Jim since 2022), and Safilo (Carrera, Polaroid, Smith) all carry major sunglass labels.
-
Rx sun lenses
ZEISS offers DuraVision Plus Sun, Mirror and Flash Mirror coatings; Shamir lists Sun Intelligence and Glacier SUN; HOYA offers a sun solutions range.
-
Polarized photochromic
Transitions XTRActive Polarized becomes polarized as it darkens outdoors, a middle ground for patients who will not carry two pairs.
-
Back-side AR
An anti-reflective coat on the inner surface reduces light bouncing off the back of a dark lens toward the eye.
In the optical
Turning sun protection into a second pair
The best moment to raise sunwear is when the prescription is being finalized, framed around the patient’s time outdoors.
Ask about time outside
Driving, boating, golf, beach and snow all point to different tint and polarization choices.
Show polarization
A polarized demo card or a glance at a reflective surface makes the difference obvious in seconds.
Price it as a pair
Presenting everyday glasses and Rx sun together keeps the decision simple and lets patients compare options side by side.
Sunglass checklist
What to confirm on any sun lens
- Labeled 100% UV protection or UV absorption up to 400 nm.
- Meets the US impact-resistance requirement for eyeglass and sunglass lenses (21 CFR 801.410).
- Optical quality: straight lines in a tiled pattern should stay straight when the lens is moved.
- Polarization when the patient works or plays around water, snow or roads.
- Polycarbonate or Trivex for sports, with a scratch-resistant coat.
- Standard sunglasses do not protect against tanning beds, snowfields, arc welding or looking at the sun; those need special filters.
Tint guide
| Gray | Reduces brightness with natural color |
|---|---|
| Brown or rose | Adds contrast; popular for golf and baseball |
| Mirror | Reduces light reaching the eye; style choice, not added UV protection |
| Polarized | Cuts reflected glare from water and roads; check UV labeling separately |
A simple front-desk service
The AAO notes that it is unclear whether UV protection in sunglasses fades over time and that an optical shop can test it. A quick UV check of a patient’s current pair is an easy way to open the sunwear conversation.
Common questions about sunglasses
Do polarized lenses block UV?
Polarization itself does not. Many polarized lenses include a UV-blocking treatment, so the label should be checked for full UV protection.
Are darker lenses more protective?
No. The AAO notes that only lenses with 100% UV protection provide the safety patients need; darkness alone is not protection.
Do inexpensive sunglasses protect?
They can. The AAO says sunglasses labeled 100% UV-blocking do not need to be expensive to be effective.
Can we test a patient’s old sunglasses?
The AAO notes it is unclear whether UV protection fades over time and suggests an optical shop can test it, which is a simple service to offer at the front desk.
Who owns Maui Jim?
Kering Eyewear completed its acquisition of Maui Jim in October 2022.
Polarized or light-adaptive?
Polarized sunwear gives the strongest glare control outdoors; light-adaptive lenses suit patients who want one pair for indoors and out.

Protect the eyes, then style the pair
Lead with UV protection and glare control, and the second-pair conversation follows naturally.
