An optician’s guide to choosing the perfect pair of transition lenses
Transition glasses, which are a brand name of photochromic lenses have been around since the early 1990s, gaining in popularity thanks to their versatility. However, many people still have questions as to what transition lenses are and their tangible benefits.
In this article, we have an engaging Q&A session with one of our experienced opticians at Eyes On. We will explain what transition glasses are, their advantages, and essential considerations when shopping for a pair of transition lenses.
Could you please explain to our readers what transition lenses are?
Certainly. Transition lenses, also known as adaptive glasses, are an advanced eyewear solution that reacts to changing light conditions. They darken in response to UV light, and clear up when in low-light or indoor environments where UV light is minimal.
Can you tell us a bit about the history of transition lenses?
Absolutely. The journey of photochromic began in the 1960s with the invention of the first photochromic lenses by Corning Glass Works, which is now Corning Incorporated. Originally, these lenses were constructed using silver halides and were only available in glass. The technology was based on the principle that certain chemicals darken when exposed to ultraviolet (UV) light, and return to a clear state when not exposed. However, the first transition glasses were slow to switch from clear to dark.
As technology evolved over the years, transition lenses experienced a significant enhancement in performance. They began to darken more quickly, achieve a darker state under sunlight, and clear up more completely when indoors.
What are the benefits of prescription transition glasses?
Transition lenses offer a variety of benefits. For one, they adapt to different lighting conditions, reducing the strain on your eyes and preventing associated problems like headaches and eye fatigue. Transition glasses also offer protection against harmful UV rays and glare. Finally, transition lenses shield your eyes from blue light emitted by screens, helping avoid problems such as eye strain and sleep disturbances.
What makes transition lenses so versatile?
The versatility of transition lenses comes from their ability to cater to a wide range of prescriptions, from single vision to bifocals or progressives. They can also be incorporated into high-index lenses, accommodating those with significant vision correction needs.
Can users select the colour of their transition lenses?
Yes, users have a choice in the colour of their lenses. The most common shades are brown and gray, but some manufacturers offer other shades like green or amber. The colour can impact how well the lenses shield your eyes from certain types of light. For instance, brown lenses can better block blue light, which is a valuable feature for digital device users.
What should customers bear in mind when shopping for transition lenses?
It’s important to consider your lifestyle and the conditions in which you’ll be using the glasses. If you are frequently in bright sunlight, transition lenses can be a very practical choice. You should also take into account your visual needs and consult with an eye care professional to determine if transition lenses are the best option for you.
The popularity of transition lenses hinges not only on their convenience but also on their ability to enhance eye health and comfort.
