Do I need a Doctor to prescribe my reading glasses strength?
If you prefer, you may see an Optometrist or Ophthalmologist, however most people initially buy reading glasses by noticing their near focus becoming fuzzy, and then grabbing a few off the shelf at the grocery store or drug store to try them out. Whichever strength adjusts YOUR view the best, AT THE DISTANCE you normally use for reading, will be the right choice for you. While this is fine for most people, a few have specific conditions that require a medical professional.
Do I need just one set of reading glasses?
Many of our customers own several glasses with different Diopters (strengths), depending on what they are viewing, and at what distance.
Below is a simple guide to determine if you should own multiple strengths:
Typical Smartphone/Cellphone reading distance: 10-12 inches
Typical Book/Newspaper/iPad reading distance: 15-17 inches
Typical Computer Screen reading distance: 20-22 inches
Most people buy the strength needed for typical Book reading (15-17 inches).
Very often that strength won't work for closer or farther reading distances.
If you use a Smartphone, try a glasses strength 0.50 HIGHER than for Book reading. If you use a Computer, try a glasses strength 0.50 LOWER.
Also, it's important to understand that your eyes change over time. A good rule of thumb to follow is:
Every 4 years = ~+0.25 strength INCREASE.
Its important to re-assess your vision every few years to see if there are changes.
Example: Let's say 4 years ago a 1.25 pair of reading glasses were fine. Today though, objects appear a little less clear or you're leaning back a little farther from your computer or newspaper to see clearly......you quite possibly need a 1.50 pair now vs 1.25 from 4 years ago.
Kerko Eyewear glasses are tough, but are they unbreakable?
Although our glasses are flexible and designed to spring back to their original shape during normal use, they WILL break if you step on them or run over them with your car.
Below is a sample comparison of durability between Kerko Eyewear glasses of different ages. In this example the Computer Readers are shown. These glasses were worn daily in a computerized office environment. You can see there is virtually no change in condition over 5 years of use!
Will Kerko Eyewear glasses scratch?
The Acrylic lenses provide consistent, uniform magnification as well as excellent scratch resistance, however, they will scratch if abused.
