Today, when you go to buy glasses online or offline, you will be provided with a range of options for your lenses after you have selected the frame of your choice. Glasses perform multiple functions in present times and are no longer just eyesight correction instruments. It is the different types of lenses available that make them multifunctional accessories.
To help you with making the right choice for your lenses, we have listed down the different options that you have, along with the functions that they perform. Read on to find out about them!
If you already have an existing pair of glasses and need a change in the lenses, you can opt for the service of reglaze glasses to get your glasses upgraded.
Prescription Lenses
These types of lenses carry a prescription as per the requirements of the individual. The prescription rating may be the same for the pair of lenses or can even vary as the eyesight correction required for both eyes may not be similar. These lenses are used for the condition of either nearsightedness or farsightedness, and this is how they differ from varifocal lenses, which is next in the discussion.
Varifocal Lenses
Even varifocal lenses are used for the purpose of eyesight correction, but there is a significant difference here. As discussed above, prescription lenses provide eyesight correction for either nearsightedness or farsightedness, but with a single pair of varifocal lenses, eyesight correction for both nearsightedness and farsightedness is catered to.
Even bifocal lenses perform the function of simultaneous eyesight correction of nearsightedness and farsightedness, but varifocals are an advancement of bifocals as they come with three visibility zones (near, intermediate, and far), unlike bifocals that have two visibility zones (near and far).
Due to the presence of an extra visibility zone in the form of an intermediate zone, varifocal lenses ensure a seamless transition while shifting the focus of eyes between things at different distances.
Since varifocal lenses are advanced in nature, it is natural for their prices to be relatively higher. However, if you wish to buy varifocal glasses at reasonable prices, you can make amazing savings by shopping for them over the internet.
Anti-glare Lenses
Being a phenomenon of light, glare is caused by light rays that are reflected in a horizontal direction after striking various obstacles. When these reflected light rays reach our eyes, one of the common problems faced by people is lack of clarity in vision. Glare is common during activities such as driving, playing sports, or fishing, and it is something that can cause irritation. To deal with glare, an effective solution is putting on a pair of glasses fitted with anti-glare lenses.
An anti-reflective coating is applied on the surface of anti-glare lenses, with a function of filtering out the light rays that cause glare. To eliminate the occurrence of glare from your daily lives, anti-glare glasses should be your go-to option.
Sunglasses Tints
The lenses of sunglasses not only have a tinted appearance but also come with an UV protective coating. By utilising these lenses, sunglasses protect our eyes from the harmful UV rays of the sun.
While buying sunglasses, look out for lenses with UV400 protective coating, as this type of coating makes 100% UV protection a possibility and ensures that you make the most out of your sunnies.
The tinted appearance that these lenses have impart an amazing fashionable side to sunglasses. While out in the sun, sunglasses are a much-needed accessory, whether it is for UV protection or for style.
Transition Lenses
If you are someone whose daily life involves switching between indoor and outdoor spaces, you have an amazing eyewear option of transition lenses for both your glasses and sunglasses needs.
Transition lenses are one of the coolest innovations that the eyewear industry has witnessed as they not only have an exceptional style element but also an amazing utility. By using a single pair, you can extract the function of both glasses and sunglasses.
The coating of photochromic dye applied on the surface of transition lenses is sensitive to UV rays. When UV rays are incident on the surface of these lenses, the UV protective function of photochromic dye gets activated, and along with this, transition lenses immediately change their appearance from fully clear to dark.
Blue Light Blocking Lenses
With digital devices becoming an integral part of our lives, most of us have seen an increase in our screen time. Although there is always scope to cut down your screen time, avoiding digital screens completely is not possible for most of us as we are dependent on them for even some of our necessary needs. So what’s the solution?
We need to understand that increase in screen time is a concern because excessive exposure to blue light emitted from digital screens can lead to problematic conditions such as digital eye strain. This is where blue light blocking glasses can be very beneficial.
When you put on a pair of blue light blocking glasses while using digital screens, their lenses – that come with a blue light protective filter – shield your eyes from blue light that is incident over them and prevent it from reaching your eyes.
