Choosing the Right Lenses

Diopters measure lens strength and should always be obtained through an eye exam to ensure you receive exactly the lenses your eyes require. Unfortunately, this may not always be possible when looking for cheap reading glasses on Amazon or from drugstore (though depending on pupilary distance this could still be beneficial).

An effective way of determining your refraction strength is using a printable guide, such as those offered by Lookoptic’s diopter chart, ICU Eyewear’s reading strength estimator, Peepers Vision Test, EyeBobs “Find Your Power” tool or ThinOptics Reading Glasses Test Strength Guide. When instructed, print the chart out on paper and hold it away from your face at an approximate 14 inch distance before looking through its lines to locate any smallest lines that you can clearly see clearly before looking through it until identifying which line represents which reading glasses refraction strength prescription this line represents your prescription strength.

Some frames feature blue light filtering technology to reduce eye strain from screens by blocking blue wavelengths that disrupt natural melatonin production and cause drowsiness. These lenses tend to be clear; however, Felix Gray has developed frames with amber tint that is clinically proven to increase secretion while decreasing blue light intensity.

The Right Frame

Frame selection is of equal importance when selecting new glasses, so choose something comfortable for your eyes. A great way to do this is visiting an eye doctor and getting a prescription tailored specifically to you – though it may cost more, prescription glasses will likely provide better vision than cheap drugstore glasses that may not meet all your needs. In addition, make sure your purchase comes equipped with diopter strength; dioptre is a unit used to measure lens power.
