Photochromic Lenses

Lenses that darken in the sunlight are called photochromic lenses. According to Wikipedia: “A photochromic lens is an optical lens that darkens on exposure to light of sufficient high frequency, most common ultraviolet radiation. In the absence of activating light, the lenses return to their clear state. Photochromic lenses may be made of glass, polycarbonate, or another Plastic.”

Photochromic Lenses give the wearer an all-in-one prescription eyeglasses and sunglasses solution. These special lenses manufactured with a special mix of chemicals that react with each other when exposed to ultraviolet (UV) rays. The ultraviolet rays cause the lenses to darken into sunglasses when outside and exposed to sunshine (aka ultraviolet rays). When the UV light is removed the lenses return to regular indoor eyeglasses Photochromic lenses do not respond to visible light - only to UV light. So, if you are outdoors or in your car and not exposed to UV light, they will not darken.  Most photochromic lenses also contain anti-glare tints which help keep the eyes comfortable.

Photochromic  lenses have been around for at least 20 years. These lenses offer the convenience of sunglasses without having to wear them over your prescription glasses or having to constantly switch between the two. But is it really as effective as it sounds? Is it worth the price?

Some of the benefits of photochromic lenses are obvious, some are not.. Here are some of the biggest pros to photochromic lenses:

  • Reduced Cost – Even though Photochromic lenses cost more than non-photochromic lenses can actually be quite cost effective. With photochromic lenses, you end up not having to buy two pairs of glasses: prescription sunglasses and normal glasses. You get the best of both, rolled into one simple solution.
  • Convenient – Photochromic lenses are very convenient because they save you from having to carry around two pairs of glasses and having to switch between them to meet different needs.
  • Limits risk of losing glasses – Carrying around two pairs of glasses means that you’re much more likely to lose or misplace one of them. Having only one pair makes it easier on you because you generally lose a pair of glasses when you are not wearing them. You wear photochromic lenses all the time during your waking hours.
  • Eye Health – Transitional lenses do more than function as sunglasses. They actually filter out a good deal of the harmful UV rays emitted from the sun, leading to healthier and happier eyes.
  • Different styles – Transitional lenses come in a myriad of styles, shades, and tints that should be suitable for anyone’s taste and fashion. To complement the three existing iconic lens colors – gray, brown and graphite green – Photochromic style colors will be available in the following four options: Sapphire – a bright, exciting hue that brings a cool factor. Amethyst – a sophisticated shade with a contemporary twist. If you are looking for better contrast to increase visual acuity for things like golfing and fishing, then photochromic brown is the color for you. If you are looking for the absolute darkest transition lens possible, you should veer towards photochromic gray.

So do the negatives outweigh the positive?

  • Ineffective in cars – Traditional photochromic lenses darken in reaction to UV rays, which your windshield blocks. Because of this, most photochromic lenses won’t darken very well in the car. However there is a  brand that will work in a car. Special Drivewear lenses work in a car but are different colors that regular photochromic lenses. They are in low light conditions a green/yellow color and change to a darker red/brown color in bright light.
  • Affected by cold weather – Photochromic lenses are also affected by colder weather, meaning they take a bit longer to react to UV rays in winter or not get quite as dark based on how low the temperatures are.
  • More expensive then clear lenses.

Should Kids Wear Photochromic Lenses?

We know that UV light damages our skin. We see advertisements on tv about suntan lotion all the time. Did you know that UV light also damages your eyes and causes cataracts later in life and that most of the damage occurs before the age of 18? Sunglasses with UV blocker that you wear on a sunny day at the beach will certainly protect your eyes but if your child wears corrective lenses then you are back with two pair of glasses and another pair to lose. Photochromic lenses checks a lot of boxes as the lens of choice for your children:

  • Any prescription can be ground into a photochromic lens.
  • Photochromic lenses will block all UV light. Even the UV light your child sees on overcast days. Yes, overcast days show enough UV light to damage your child’s eyes over time.
  • Polycarbonate lenses can be photochromic.
  • Photochromic lenses also block Blu light. So when your child is on the computer or watching tv, your child’s eyes will be less tired which makes studying more effective.
  • Kids think lenses that change color or “cool” and are more likely to wear them more often and less likely to lose them.
  • One pair of glasses are less expensive than two pairs of glasses.

So the answer is yes! Kids should wear photochromic lenses. Kids like them better so less likely to lose them and they protect your child’s eyes from any level of harmful radiation.
