All of us make decisions daily on what to wear, how our hair style should be, which colors to combine to show off that new pair of boots. Likewise, we have the ability to make the decision on what color our new pair of eyeglasses will be, based on our personal taste on the color palette and frame material. On the most important part of the eyeglasses though, is on what we have no control over, whatsoever: The lenses.The type of lenses each of us might need, depends solely with the problems that ones’ sight might be facing. For this you need the assistance of an optometrist or ophthalmologist, as only they can provide you with your prescription. The fact though that you are not able to choose your own type of lenses, it does not mean that you don’t have every right to know what you are purchasing.
Listed below are the most common types of lenses you can find on a prescription and the types of lenses that are mostly used in the eyeglasses industry.
Single Vision Lenses
Single vision lenses are one of the most common types of lenses you will encounter when dealing with prescription glasses. As its name suggests this lens has a single field of version ideal for correcting either nearsightedness also known as myopia or farsightedness known as hyperopia.
Bifocals are the best of both worlds, where single vision lenses correct either near or farsightedness, due to bifocals having two corrective sections they are able to do both. This allows them to help with a wider range of more severe vision disorders.
By now you may have guessed it, trifocals have a third region for those needing intermediate vision correction. Trifocals are predominantly used by people with advanced presbyopia.
Progressive lenses are the 2.0 of bifocals and trifocals, by that we mean they accomplish the same job as the bifocals and trifocals, while providing a better experience for the wearer.
By allowing seamless transitions between the viewing areas, there is no visible line in the lenses unlike the bifocals and trifocals.
Screen Or Computer Lenses / Photochromic
We have included computer lenses to this list as although they are technically not a “prescription lens” with our electronic devices becoming part of us these days, we believe they are as important as all the rest. Computer or photochromic lenses are able to filter out the blue light emitted by our computers or smart phones, greatly decreasing headaches and eye strains.
We trust that the above list has given you an insight on the type of lenses in the market and that now you will be purchasing your ideal pair knowing exactly what it is you are buying. Your perfect fit is out there and you are equipped with the knowledge of what your prescription lenses are all about.
