Frequently Asked Questions

What are the benefits of lens coatings?

Lens coatings can enhance the durability, performance, and appearance of your eyeglass lenses. Anti-scratch coating: It is recommended for all lightweight and softer plastic lenses. The scratch-resistant coating has a much harder surface that is more resistant to scratching, whether from dropping your glasses on the floor or occasionally cleaning them with a paper towel. 
Anti-reflective coating: this coating helps to eliminate reflection to improve visibility and eye contact. Recommended for all lens types,

UV-blocking treatment: UV protection is built into most high-index plastic and polycarbonate lenses, but you will need to have a UV-blocking coating put on to CR-39 plastic lenses.

Photochromic treatment: Available for almost all lens materials, this treatment causes lenses to darken automatically in sunlight and return to clear when you go back inside

How to Choose the Right EyeGlasses Frame Material ?

Eyeglass frames are made out of many different composite materials and formulas, but the basic groupings are metal and plastic. Plastic frames are the most popular choice because they usually are less expensive, are lightweight and come in a variety of colors and styles. Nylon is often used in sports sunglasses due to its impact resistance and flexibility. Among the metals, monel is most common, followed by titanium, Flexon, stainless steel, nickel silver, and aluminum. Wood eyeglasses frames also have become a hot eyewear trend.
Most people who choose eyeglass frames are concerned with price and style. But there are other factors to consider, such as how lightweight, strong, flexible and corrosion-resistant the frames are.

What is the difference between Single Vision, Bifocal and Progressive lenses

Single vision is the most common type of prescription lens. This lens type features a single field of vision, or one prescription power throughout the entire lens, for correcting nearsightedness (myopia) or farsightedness (hyperopia). Single-vision lenses are also used for reading glasses. Some people need glasses for distance as well as reading. Instead of having a separate pair of single-vision glasses for each, bifocals or progressives may be a more convenient option. Unlike single vision, bifocals and progressives are multifocal lenses Difference between bifocal and progressive lenses is that bifocal lenses have two viewing areas divided by a visible line, a larger viewing area for distance with a smaller segment for reading. Whereas Standard progressives are multi-focal lenses with three viewing areas, distance-, intermediate-, and near-vision. Unlike bifocals, there is no visible line between each viewing area. They have a seamless, invisible design where the power “progressively” changes throughout the lens.

What is blue light coating ?

Blue light is a naturally occurring wavelength of light. There are many sources of blue-violet light, found all around us. It is produced by smartphones, tablets, computers, flat-screen TVs, and even the fluorescent and LED lighting in your home. However, the blue light emitted from these devices can reach unhealthy levels for many people with modern lifestyles.
A large number of people, using devices with digital screens for at least two hours a day, report suffering from eyestrain, headaches, or dry eyes. Clinical evidence has demonstrated a reduction in eye strain and eye fatigue plus a decreased risk in damage to the retina by reducing damaging blue light entering the eye. Wearing eyeglasses with blue light lens coating prevents most damaging blue-violet light rays from reaching your eyes. With a higher contact angle than standard anti-reflective coatings, blue light lens coating selectively reflects blue-violet light to help protect the retina.

How to clean my Glasses

Caring Glasses
1. How do I clean my glasses?
Cleaning your glasses routinely and correctly is just one of the ways to keep your glasses looking like new.
Glasses are prone to scratches and scuffs when left lying around, and while we recommend storing your glasses in a protective hardshell eyewear case.
Safe method to clean your eyeglasses is to use spray eyeglass cleaner and a soft microfiber cleaning cloth to clean your eyewear the way the professionals do.
Some household glass cleaners and chemicals have ingredients that can actually cause harm to your glasses and even damage any common anti-reflective (AR) coating applied to your lenses.

I have "spots" floating around in my eye. Should I be worried?

Spots and floaters are usually harmless. Consult your optometrist to dertermine the cause.

I work on a computer all day. Can this hurt my eyes?

Computer monitors emit levels of radiation that are considerably lower than the maximum allowed for safety, according to a study by the National Institute for Occupational Safety and Health. NIOSH compared the maximum radiation levels in a group of monitors with the safety standards. A study of monitors reported in the Optical Laboratories Association CLEARVisions magazine found that:
  • X-rays: none
  • Ultraviolet: more than 1,000 times below the standard
  • Visible: more than 10 times below the standard
  • Infrared: none
  • Radio Frequency: - Electrical Field: 5,000 V/meter2 of 377,000 allowed - Magnetic Field: .09 A/meter2 of 2.65 allowed
  • Extremely Low Frequency: equal to common household appliances, well below dangerous levels (no standard exists)

What exactly does "20/20 vision" mean?

"20/20 vision" is commonly accepted as the standard of normal distance vision for a human being. Basically, it means "good visual acuity at 20 feet." So if your vision is 20/20, you can read certain sizes of letters on a Snellen chart clearly at 20 feet or closer. But if your friend has 20/15 vision, his visual acuity is better than yours: you would have to stand 15 feet away from the chart to read the smaller letters that he can read while standing 20 feet away.  By the way, visual acuity at a distance isn't the only measure of how good your vision is. You could have 20/20 distance vision but still, have difficulty seeing at night because of poor contrast sensitivity. Or you could have near vision problems because you're over 40 and experiencing presbyopia.
