Optical FAQs


What is the difference between a no-line progressive vs. line bi-focal lenses?
Lined bi-focal lenses, as the name implies, separates distance from close-up vision by a visible line. No-line progressive lens technology blends distance range, mid-range and close-up range so that there is no sudden “image jump” from distance to near. The field of vision from distance to near follows the natural downward progression of the eyes. EyeOne Optical highly recommends no-line progressives.

How to use Progressive Lenses?
Wearing progressive lenses require time for your eyes to become adjusted because you will change the way you use your eyes. First, put your old glasses away and wear the new ones full-time. You will learn the position for close-up reading, mid-range and distance vision. Test your new lenses by looking through different spots on the lenses to find the “sweet spot” for each distance. If you are not able to adapt in two weeks, visit your local optician.

What are Photochromic or Transition lenses?
Transition lenses are daily eyewear lenses designed to quickly adjust and adapt in changing light to help protect from the sun’s rays and enhance the vision of eyeglass wearers. It is important to remember that transition lenses do not replace polarized sunglasses. Transition lenses do, however, offer full UV protection.

Are Transition lenses made better today?
Over the past two years Transition lenses have greatly improved. There is a type of Transitions which will work well in a vehicle and also while being indoors.

Are Transition lenses available for children and adult sport glasses?
Yes, and they are very beneficial in all outdoor activities.

What is a no-glare or anti-reflective (branded as Crizal) lens treatment?
Non-Glare treatments dramatically reduce glare. Anti-reflective treatments allow more natural light to your eye which allows you to see more crisp and clear. It also takes the glare off of your lenses so others can see your eyes and also reduces eye fatigue and eye strain associated with computer use and/or artificial lights. No-glare treatments also reduce hallows and starburst from lights when driving at night.

What is the difference between EyeOne’s Basic and Premium no-glare options?
Basic No-Glare has fewer coating layers, requires more frequent cleaning and is not as easy to clean.Premium No-Glare has more layers which repel water, dirt, oil and dust and reduces the need to clean lenses more frequently. It makes lenses look superior to other lenses without a no-glare treatment. EyeOne proudly uses Crizal products. 

What is Scratch Coating?
For extra durability, scratch-resistant coating lengthens the life of your eyeglasses by adding resistance to damage and general wear and tear caused through daily use.

What is a UV Protective Coating?
An ultraviolet treatment coating is not visible to the naked eye, but works to protect vision much like sunscreen prevents skin damage from the sun. UV protection may not be necessary for some polycarbonate or high-index eyeglasses, as those lenses often shield ultraviolet rays. The invisible UV may prevent cataracts, retinal damage, and other serious eye problems attributed to the sun’s rays. Many lenses EyeOne offers already come with this but an Optical Staff member can help you decide if you need this for your lenses.

What is the difference between polarized lenses and Transition lenses?
Transition lenses are light-reactive or UV refractive. They darken when exposed to UV light so more UV exposure the stronger the tint. Indoors, the lenses go virtually clear. Polarized lenses are normally of fixed tint. They have a polarizing filter which filters blinding glare. They are ideal for outdoor daytime uses ranging from skiing to cycling, fishing to watersports, and of course for driving in sunny conditions.

Why shouldn’t I order eyewear on-line?
Most important is that every pair of glasses is a custom-made item. Everyone’s head and eyes are different therefore your optician must take various measurements for a proper fit. There are different designs and materials for both frames and lenses and different lens treatments. At EyeOne an Optical Staff member will assist you throughout the entire process. At EyeOne, we will bill your vision plan insurance, adjust or repair your glasses when possible, fulfill warranties and assist you in making the right choice in eyewear to match your lifestyle.

What is the Importance of Safety Eyewear?
Safety eyewear protects your eyes while you work or play in situations that are high risk for eye injury. Impact resistant lenses which meet OSHA’s eye and face protection standard, 29 CFR 1910.133, requires that eye and face protection be certified. Wearing safety eyewear at work or in other practical situations is eye smart.

What should I use to clean my glasses?
A micro-fiber cleaning cloth and eyeglass cleaner that you can purchase at your optical shop.

What are Computer Glasses?
Computer glasses have a larger area of intermediate vision (arm’s length away) than traditional progressive lenses. Adding an anti-reflective treatment reduces the eye fatigue and strain from extended computer used.

When does my Eye Glass Prescription Expire?
Eyeglass prescriptions do not expire unless your eye doctor feels there is a medical reason which would warrant an expiration date. However, EyeOne Practitioners and Opticians encourage you to get an annual eye exam. Most vision plans provide for an annual or biannual benefit for an eye exam.
