How To Take Care Of Your Blue Light Glasses
EXYRA blue light glasses not only improve your vision, they also shield your eyes from UV rays and blue light. It just so happens that EXYRA glasses are quite fashionable, too!
Here are several ways to protect your eyeglasses.
Sanitize Your Eyeglasses
Each pair of EXYRA glasses comes with a premium lens cloth. Clothing and tissues shouldn’t be used to wipe your glasses. You might inadvertently take off the protective coating on your glasses if you use these materials. For optimal results, your frames should be cleaned on a regular basis with mild dishwashing soap, warm water, or a lens cleaning solution. Be careful when holding them - lenses are delicate no matter how sturdy the frames are.
Use a Case to Carry Your Eyeglasses Around
Each pair of frames we offer prevents glasses from getting crushed or scratched. People who keep their eyeglasses on their head don’t realize they are warping the frame’s form by doing so. The result: a frame that slips off your face.
Eyeglasses Shouldn’t Be Left in Hot Cars
Don’t let your eyeglasses sit on your vehicle’s dashboard. Severe heat can warp your frames and damage your lens. Think of your windshield as a magnifying glass in the sun.
Take Care of Your Eyeglass Frames
Use both hands when putting your eyeglasses on and off. When you do so with a single hand, your frames will gradually become looser. For correct application, use two hands to slide your glasses above your ears, then place them on top of your nose. To remove your eyeglasses, raise the frame’s arms, then pull them off your face.
Much like your automobile and home, your EXYRA glasses warrant regular care. We have small eyeglass screwdrivers to fasten screws on the frames if they become loose.
Fastening Loose Frames
Loose eyeglasses are a nuisance. They could slip right off your face and get damaged if you suddenly move. An expensive optometrist visit is needed when your eyeglasses warrant repairs. However, repairing loose frames can be done on your own with an eyeglass repair kit.
Fasten the screws on both sides of the frame. You’ll find a small screwdriver in your eyeglass repair kit. This tool can be used to keep the legs of the frame on the front of the eyeglasses.

How to Measure Pupillary Distance ?

Follow the guide below for simple, step-by-step instructions to measure your PD at home.
How to read your glasses prescription?
In the example below, we learn how to read the eyeglasses prescription, you will need to understand what the symbols mean first.
Right Eye and Left Eye Abbreviations
Since we’re nearly always looking at prescriptions for two eyes, you’ll nearly always see two sets of numbers, one for the left eye, and one for the right.
OD: Oculus Dextrus as means right eye in Latin.
OS : Oculus Sinister Latin terms for left eye.
OU: Your prescription may or may not contain this one. It stands for oculus uterque which means both eyes
Lens Power
Sphere (SPH) – This shows the strength of your glasses, or lens power, measured in diopters (D). A negative (-) sign indicates nearsightedness (in which case you have myopia) while a positive (+) sign or no sign at all indicates farsightedness (hyperopia).
Cylinder (CYL) – This shows the lens power for astigmatism, the condition of having an irregular lens shape caused by both nearsightedness and farsightedness. It is measured in plus and minus diopters as above. If the Cylinder field is empty, you have no astigmatism so there is no correction needed.
Axis – This is a number from 1 to 180 which describes the lens meridian that contains no cylinder power to correct astigmatism. If your eyeglass prescription has a Cylinder power, it must also have an Axis value (sometimes preceded by an x when written in freehand).
Add – This field contains any added magnifying power for people with presbyopia (or aging vision) and is featured in the bottom part of a multifocal lens. As a result, this is always a positive (+) number and is usually the same in both eyes.
Prism – This is for the uncommon occurrence of eye alignment problems. It is measured in Prism Diopters (p.d. or a superscript triangle if written freehand).
Base – This refers to the thickest edge of the Prism, which is also the direction towards which the Prism redirects light (up, down, in, or out)
PD: Pupilillary Distance (PD) or interpupillary distance (IPD) is the distance (the industry standard is to measure in millimeters) between the centers of the pupils in each eye. This measurement is used when preparing to make prescription eyeglasses take a look at our PD measurement tips for more information.
An Example Of An Eyeglass Prescription
A good rule of thumb when reading a prescription is this: the further from zero each number is, the worse your eyesight.
In above example, the optometrist has prescribed -2 D sphere for the correction of myopia in the right eye (OD). There is no astigmatism correction for this eye, so no cylinder power or axis is noted.
The left eye(OS is being prescribed -3 D sphere for myopia plus 0.5 D cylinder for the correction of astigmatism. The Cyl power has its axis at the 180 meridians, meaning the horizontal (180-degree) meridian of the eye has no added power for astigmatism and the vertical (90-degree) meridian gets the added 0.50 D.
