  • What Makes Wohl Optics Different?

    One on one consultation from the person who is not only going to be consulting with you, but also designing, manufacturing and dispensing your eyewear.  You get expert lens advice.

    Wohl Opticians are highly skilled eye care professionals with rigorous and extensive training to fulfill education and practice competencies in Opticianry.  All ophthalmic lenses require precise measurements to be taken from your face and eyes, and the results must be accurately transferred to the eye wear. This is not a simple task; should your Registered Optician make a mistake as little as 1mm, you may not be able to use your new eye wear.

    We take a lot into consideration when it comes to our patients and eye wear. Some lenses are specifically made for people of different ages, and even some that are made to allow for a person's posture and even eye and head movement.

    Remember that your Registered Optician is highly trained to provide you with choices from the simplest aspect of corrective lenses to the most complicated.

    What does Wohl offer Patients who Purchase Eyeglass Frames from them?

    Free maintenance for the lifetime of eyewear including but not limited nose pad and screw replacement, temple and frame front realignment custom to the wearer and cleaning of residue buildup from skin or other material.  We want you coming in every few months even if there is no apparent problem; we can straighten, tighten and diagnose. This will help avoid areas or things that will avoid future problems.

    What is Cataract? A cataract is a medical condition where person’s eye lens becomes opaque due to the aging or disease like diabetes or hypertension.
    Where is Polycarbonate used? Polycarbonate is a lens material that is characterized by its lightness, high refractive index, impact resistance and U.V absorption.
    What are Bifocals? Bifocal lenses are designed into two separate parts, which gives the user the freedom of seeing objects nearby and farsighted without changing the glasses. Most of the time the "reading" area is smaller, shaped like a sideways "D", and found in the lower hemisphere of the lens. These bifocals are called lined bifocals or flat-tops. If you are focusing on distant objects, you look through the top half of the lenses. To read a book, magazine, or newspaper, you look through the "reading" area.
    What is the Difference between Bifocal lenses and Progressive lenses? Both these lenses are same but, Progressive lenses with their multiple focal distances easily adapt to the environment or adjust your eyes for the vision.  While, the Bifocal lenses will take some time to adjust the vision from a distance to nearby or vice versa.  One setback with Progressive lens is that it creates a vision that is slightly distorted compared to Bifocal lenses.
     What is Anti-Reflective Coating? Normal lenses often create glare, reflections, and "ghost images." Now that can be eliminated with an anti-reflective coating.

    What we see is a result of light being sensed by our eyes. With normal glasses, much of the light reflects off the lenses. This produces glare. It also reduces the wearer's visual acuity. In other words, the light reflections are a visual and cosmetic problem.

    Anti-reflective coatings increase light transmission through the lenses to 99.5 percent. They make it easier to see and easier for others to see you. These coatings are especially useful for those viewing computer screens and driving at night.

     Will Polarized Lenses help me When Driving? Yes. Glare from wet roads, light reflecting off other vehicles, and glare from your own windshield can be annoying and dangerous. To eliminate this glare, we offer polarized lenses. Polarized lenses significantly reduce glare, decreasing eye strain and increasing visibility. Polarized lenses are the most effective way to reduce glare.
     What is Polycarbonate and Trivex?  Polycarbonate or trivex are a good choice for active lifestyles, moderate prescriptions, or safety glasses. These materials are about 20% thinner and lighter than standard plastic lenses. Also, they provide the most impact resistance of any material available, which means they are less likely to shatter when impacted at high speeds. Finally, these materials are recommended for semi-rimless and rimless frame designs because they do not tend to chip or crack.
     What is Astigmatism?  Astigmatism is a vision condition that causes blurred vision. It is usually caused by either irregularly shaped cornea which is the the clear part of the eye or curvature of the lens inside the eye. Most people have some degree of astigmatism. Slight amounts of astigmatism do not distort vision and do not require treatment. However, larger amounts can cause blurred vision, double vision and headaches. Astigmatism is often associated with myopia or hyperopia, and usually occurs from birth. It may be hereditary, or it may develop later as a result of an eye injury or aging. Eyeglasses, contact lenses, or refractive surgery can correct moderate to high degrees of astigmatism.
     What is Farsightedness? Farsightedness is when either the eyeball is too short or the cornea has too little curvature, so the light is not focused correctly. As the name suggests, people with farsightedness are able to focus on objects that are further away, but have difficulty focusing on objects which are close.
    What is Hyperopia? Farsightedness. Able to see far, but not near.
    What is Nearsightedness? People with myopia have hard time seeing distant objects, but have no difficulty with reading up close or working on a computer. In addition to poor distance vision, symptoms of myopia could be eye fatigue, squinting and headaches. People with severe myopia are at a higher risk of retinal detachment and therefore must be monitored regularly. Myopia can be corrected with eyeglasses or contact lenses.
    What is Myopia? Nearsightedness.  Able to see near, but not far.
    What is Presbyopia? Presbyopia is a natural aging process of the eye. It occurs when eyes lose ability to focus on near objects. As people get older, usually when they hit their mid to late 40s, they start having difficulty seeing in low light, problems reading a book, etc. The ability to focus on near objects declines throughout life. It is normal.
    Why do You Need an Eye Exam?

    During an eye exam, your eye doctor regularly screens for many diseases that can be easy to miss until symptoms become severe and irreversible. Some of these diseases include diabetes, high blood pressure, eye tumors, eye infections, dry eyes, glaucoma, macular degeneration, retinal detachment, and more.

    So while you may think you only go the eye doctor to get an updated prescription or to order new glasses or contacts, there are many critical health reasons to see your doctor at least every two years. When was the last time you visited your eye doctor?

    Why are Sunglasses so Important?

    1.) UV Protection. The sun's UV radiation can cause cataracts; benign growths on the eye's surface; and photokeratitis, sometimes called snow blindness, which is a temporary but painful sunburn of the eye's surface. Wide-brimmed hats and caps can block about 50 percent of UV radiation from the eyes but optometrists say that is not enough protection.

    2.) Blue-Light Protection. Long-term exposure to the blue and violet portion of the solar spectrum has been implicated as a risk factor for macular degeneration, especially for individuals that are “sun sensitive.”

    3.) Comfortable vision. The sun's brightness and glare interferes with comfortable vision and the ability to see clearly by causing people to squint and the eyes to water.

    4.) Dark adaptation. Spending just two or three hours in bright sunlight can hamper the eyes' ability to adapt quickly to nighttime or indoor light levels. This can make driving at night after spending a day in the sun more hazardous.

    5.) Skin Cancer. Cancer of the eyelids and skin around the eyes is more common than people think. People should wear sunglasses outdoors whether they are working, driving, participating in sports, taking a walk, running errands or doing anything in the sun.
