Do Men’s Prescription Sunglasses Have Medicine in Them?

Prescription glasses may be found almost everywhere (you’re probably even wearing a pair of them right now). Due to their widespread use, it's easy to forget how these wonders are manufactured in the first place. It turns out that much more than just placing a piece of polypropylene plastic and a lens into the frame goes into each pair of men’s prescription sunglasses. 

 

So, Do Men’s Prescription Sunglasses Have Medicine in Them?

The answer is no. Regular prescription glasses or sunglasses don’t have any sort of medicine in them. These glasses are referred to as “prescriptions” because they correct an issue unique to your body, much like a drug dosage. They are simply ground bits of glass fashioned to concentrate the light entering your eye, allowing the light to be focused onto the retina after passing through the natural lens. It's good old-fashioned physics, and there's nothing "medical" about it.

How Are Prescription Sunglasses Made?

The gradual transition from plain glass to polycarbonate lenses in the 1900s made it possible for modern men’s prescription sunglasses to be significantly more lightweight, long-lasting, and easily available to the general public than they were several centuries ago. The process starts at an optometrist's clinic, where the patient gets an eye exam to obtain an up-to-date prescription.

Based on the prescription provided before checkout, the online eyewear company grinds, angles, and edges each lens into the shape and size necessary for enhanced vision. After the lenses have been treated with an ultraviolet (UV) coating and tinted, if desired, they are prepared to be inserted in the frame and worn by the patient. A prescription for glasses will often contain values like:

Axis: A measurement value between 0 and 180 degrees that indicates astigmatism's direction. 

Cylinder Base Power: A negative and positive value indicating the amount of astigmatism.

Spherical Base Power: A negative and positive value indicating nearsightedness or farsightedness.

Now that you know how prescription sunglasses are made (without any medicines), it’s time to upgrade your old pair of prescription sunglasses with a stylish frame from Reks eyewear.
