The eye doctors at Vision World keep talking about common refractive errors of nearsightedness and farsightedness, but what does it all mean? When light rays pass through the eye, they are bent by different densities and curvatures. When these rays do not properly converge to a focal point on the retina, it is a refractive error. Through an eye exam at our Mineola eyeglass store, our optometrists can measure the error in the path of these light rays to determine your appropriate prescription for corrective eyewear or lenses.
During a typical medical eye exam with our optometrists at Vision World, we are examining the general health of your eye, searching for evidence of eye disease. However, determination of refractive error is often done to help diagnose and treat eye diseases. Refraction is different from the determination of refractive error. For those who already wear vision correction devices, our Mineola eye doctor can determine the power of the patient’s current glasses. Based on the current glasses power, medical history of the patients, the determined refractive error, and any additional information from your medical eye exam, your eye doctor can select the optimal corrective lens power for each eye. After considering the need for specialized lens materials, your optometrist will write up a prescription for glasses or contact lenses.
Once you have your prescription in hand, you can shop through our large inventory of designer and budget-friendly eyewear. Our opticians will assist you in choosing the best pair of eyeglasses to suit your style. Next, they’ll fill your prescription, taking into account any lens recommendations made by the eye doctor and any specialty coatings you want, like scratch-resistant or UV-protection.

Many people are under the assumption that they only need sunglasses on sunny days during the summer months when they tend to be outdoors more. The truth is that sunglasses help to protect your eyes from ultraviolet rays all year long, including cloudy days since ultraviolet rays can penetrate through the clouds.
A good pair of sunglasses can help prevent cataracts due to years of direct eye exposure to ultraviolet rays. I am not referring to the over the counter designer replica sunglasses as most offer three problems.
First, most cheap sunglasses use a low end lenses that can actually hurt your eyes by making them strain even without you being aware of the problem.

In you wear eyeglasses then you know they can’t be perfect in all situations. You have a prescription that solves a problem such as long or short sightedness, but you still find yourself looking over the top of the glasses or having trouble focusing through them for certain viewing tasks.
Many people who wear eyeglasses remember the days of big, bulky, cola-bottle lenses that were not only unattractive, they were heavy and uncomfortable to wear. With new technology, thinner lenses are being created and they’re not only more appealing, they are lighter and more comfortable to wear. A newer type of lens gives thin lenses a far more attractive look. Aspheric lenses completely changed the way people wear glasses. Traditional lenses have a spherical surface – like a baseball – so it has the same curve going across the entire surface of the lens. Aspheric lenses, on the other hand, gradually changes in curvature from lens center to the outer edges – giving the lens a more attractive profile.
