Choosing the Best Prescription Lenses for Your Eye Care Needs

May 28th, 2018

There are four important considerations you have to be mindful of when purchasing prescription lenses: vision, comfort, safety and appearance.

Know the Difference between Eyeglass Lenses.

While your optometrist jacksonville, determine the best specification for your eye care needs through a thorough, comprehensive eye exam, it is still essential to understand your individual needs by evaluating your past experiences with prescription eyeglasses by reviewing your old pair of glasses.
 
When you visit your eye doctor in jacksonville fl, remember to bring your existing eyeglasses so our professional team can properly assess what about your current eye wear is working or not working to meet your specific needs.
 
If it is your first pair, our optometrist will conduct a very thorough interview in order to obtain clearly your vision needs, to assess your eye wear needs and prescribe eyeglasses to best suit your vision needs.
 
Your eye doctor will take most of the guessing work out of what your prescription lenses require but there may still be some options for you to choose from depending upon your specific requirements. To better understand your options, let us elaborate the function of each type as follows:

 

Types of Eyeglass Lenses:

 

Single Vision

Single vision lenses are one of the mostly widely known types of lenses, they can be used for distance and reading prescriptions to correct refractive errors. These lenses can be found in a large number of materials and have additional coatings and features added depending on the wearers desires and prescriptive needs.
 

Freeform

Freeform or surface lenses are a new technology offered in eye glass lenses that are a go-to for our eye doctors. That is because of the increased optics and reduced aberrations that a large number of patients can experience from traditional lens manufacturing methods. These smart lenses are processed in a way that how the wearer looks through the lens is predicted to provide optimal vision with the most accurate lens power and crisper vision.
 

Progressive lenses

Progressive lenses are an extremely popular type of lens for a large number of patients when they reach their 40’s. These very special lenses offer three different ‘zones’ to look through; distance, intermediate (for your computer screen or the dashboard of your car) and reading (for your digital devices and printed materials).
 
The reason for their increased popularity is their convenience of allowing the wearer to essentially have three different pairs in one! This easy progression in the lens between different corrections that couldn’t be achieved previously with bifocal and trifocal lenses from the elimination of the partition(s) making.
 

Bi-focal and Tri-focal lenses

As mentioned earlier in the single vision section, reading glasses are commonly prescribed for people who only require a little help seeing small print more clearly. Bifocals and trifocals lenses have specialized areas for this particular function. The top part of these type of lenses aids the eyes for distance viewing, while the bottom part helps the eyes view close objects with greater ease.
 

Materials:

There are different options available when it comes to the material of your eye glass lenses that have different safety, and cosmetic benefits:
 

Polycarbonate lenses

When it comes to durability, polycarbonate lenses are the preferred choice. They are impact-resistant and highly resilient, perfect for outdoor activities and individuals who may not be able to take good care of their eyeglasses, such as children. These lenses are so sturdy, it is used on rimless eyeglasses. Another feature of polycarbonate lenses are their built-in UV filters which protects the eyes from the dangers of harmful ultraviolet rays.
 

Hi-index lenses

Previously high prescriptions were thick and heavy, weighing on the nose and providing a sometimes-unattractive esthetic, however with Hi-Index Polycarbonate materials this can now be avoided! These lenses are made of thin plastic and provide a thinner, lightweight option for both high plus and minus prescriptions. It is the perfect answer for the fashion-conscious with stronger prescription eyeglasses needs, allowing the wearer to choose from a larger number of different frame styles and materials not previously available to them.

Trivex

Another lightweight option available to glasses wearers, this material provides lightweight protection similar to polycarbonate. It was developed to be used in military helicopter windshields as well as on fighter jets. They are an impact resistant option similar to polycarbonate, both a lightweight, durable plastic; the only difference is in how the lenses are formed as trivex is cast-molded vs poly which is injection molded.
 

Features:

You can take a step further and enhance the function of your lenses to better accommodate your eye care needs by applying coatings. The following are your options:
 

Photochromic coatings

As we fight our constant exposure to the harmful rays of the sun, the demand for photochromic lenses is more prevalent than ever. Photochromic coatings include tints with UV protection, polarized coatings and transitions. Transition coatings immediately darken when they are being exposed to sunlight, which make them a great substitute for sunglasses under fair exposure. All lens types can be upgraded to photochromic that is why it is a popular choice for all ages and conditions.
 

Anti-reflective coating

Anti-reflective coatings sharpen vision by reducing eyestrain, they eliminate most reflection and glare produced by artificial and organic lights. Anti-reflective coatings also make the eyes appear clearer behind the eyeglasses.
 

Blue light reduction coating

Blue light reduction coating significantly decreases the eyes’ exposure from blue light being emitted by digital screens, and most modern devices. This coating also optimizes the user’s visual performance decreasing eye strain that results from viewing digital screens for long periods of time.
 

Scratch-resistant coating

Scratch-resistant coating adds layer of protection to your lenses for preventive measures. It decreases the possibility of light to moderate scratches on your lenses which interferes with the wearer’s vision. There are no such things as scratch-proof lenses, but a scratch-resistant coating increases the initial quality of your lenses.
 

UV protection

It’s our duty to our eyes to keep them get protected against ultraviolet rays that pose a serious threat to our eye health. Ensure your lenses have adequate UV protection, most lenses have some UV protection built into them, however, an added application of UV protection coating can deflect up to a 100% of transmitted and reflected UVA and UVB rays.
