Glasses are one of those accessories that is worn at a very large scale. This was not the case earlier. But with development in the eyewear industry, glasses now perform a wide range of functions. The other very important reason for their popularity is the fact that glasses are also considered as a solid fashion accessory by a significant section of the public.
Last week, while looking for aviator glasses for men over the internet and after arriving at a pair with metal frames, I was amazed by the multiple choices of lenses that were being offered.
Here are the different types of glasses that you need to know. The classification is based on the different types of lenses that these pairs utilise.
Prescription Glasses
Prescription glasses are those pairs which provide the function of eyesight correction. By using the principles of light, the lenses of these glasses are designed in such a way that they provide clarity in vision.
You can get your prescription glasses customised as per individual prescription. The glasses that I bought last week over the internet were a pair of aviator prescription glasses. During the purchase process, I selected prescription lenses, and submitted my individual prescription. The glasses were delivered to me with the exact prescription submitted.
Fake Glasses
Basically, fake glasses are non-prescription glasses used solely as a fashion accessory. These pairs are a hot trend in present times as many people now wear glasses just for their fashion needs. And rightly so, as you should have not just one pair of glasses, but multiple pairs for all moods and occasions.
Blue Light Blocking Glasses
The use of digital screens has increased with fast-pace digitalisation. And ever since the COVID-19 pandemic set in, the dependence on digital screens has been even more.
With increase in screen time, the exposure to blue light emitted by these digital screens has also increased. This is where there is a health concern. When our eyes are exposed to excessive amounts of blue light, it might cause conditions like eye strain, dry eyes, headaches, among others. This is where blue light blocking glasses become important.
The protective coating applied to the lenses of blue light blocking glasses prevents blue light from passing through and reaching our eyes.
Since I have a high screen time, I also chose the option of blue light protective coating for the aviator glasses that I bought recently.
Anti-glare Glasses
Glare can cause lack of clarity in vision and is caused by light rays that are reflected horizontally off a surface. It is experienced very frequently during activities like cycling, boating, driving, sports, among others. However, glare can occur at any time of the day and at any place. So going for anti-glare glasses is advisable.
The thin anti-reflective coating used on the lenses of anti-glare glasses are super effective in blocking the reflected light rays that cause glare. By getting your glasses updated with anti-reflective coating, glare can certainly be eliminated.
Sunglasses
Your eyes need protection from the harmful UV rays of the sun, and nothing can do this better than a pair of sunglasses. By putting on sunglasses in sunny conditions, you can eliminate the risks associated with UV rays exposure to eyes.
Sunglasses keep our eyes protected from the harmful UV rays with the help of UV protective coating on their lenses. If your lenses have both UVA & UVB protective coating, then 100% UV protection is guaranteed.
Even among sunglasses, there are various types such as polarised sunglasses, mirrored sunglasses, among others.
Recently, while scrolling through instagram, I came across some amazing sunglasses collections from an eyewear startup in the UK. You can check them out here at Specscart Instagram.
Transitions
Transition lenses are one of the coolest inventions in the eyewear space. Transition lenses are designed to be light-sensitive. This light-sensitive nature of transition lenses makes them adjust the colour of their tints according to the intensity of light that falls over their surface.
When fitted into glasses frames, transition lenses act both as normal pairs of glasses with clear lenses and also sunglasses.
If you go for transition lenses, you will not require to switch between glasses and sunglasses while making a shift from indoors to outdoors, or vice-versa. Also, the need to carry two separate pairs is also done away with.
Varifocals
Varifocal lenses are recommended for those who need eyesight correction for both nearsightedness and farsightedness, and anything in between. Varifocals make this a possibility in a single pair of lenses by using multiple focal points.
In varifocal glasses, there are three visibility zones – near, far, and intermediate. These three different visibility zones cater to eyesight correction for different ranges of distances.
The amazing thing about varifocals is that the boundaries dividing the three different visibility zones are not visible to the naked eye, whereas in the case of bifocals, these boundaries are visible. Hence, there is no compromise in the visual appeal of varifocals.
