Contact Lenses 101 & Caring For Them

Contact lenses have become quite popular today and many people are choosing them over their regular spectacles for daily use. One of the main reasons why contact lenses have become popular is that they are easy to use, comfortable and moreover, great for the wearer’s appearance. Believe it or not, spectacles do add a new dimension to the wearer’s appearance and contacts can give back that unadulterated look back to the wearer.

Contact Lens

But with so many variants available in the market, a prospective buyer might feel baffled at the choice. Many people are scared to put contacts in with many misconceptions that are formed due to less or no information about how a contact lens works. Here are some useful short facts to help a prospective buyer feel more confident while purchasing a new contacts or even the first contacts.


There are many types of Contact Lenses and they differ not only in the composition they are made of, but also in the tenure of their use, the comfort level and even appearance. Contacts are basically thin disk like shapes made out of silicone or special plastic. These disks are worn over the lens of our eyes and they float over the surface. These floating lenses move with our eyes and provide vision correction or add to the aesthetic appeal. They are also handy since there’s no added weight over your nose or temples/ears like when you’re wearing spectacles. These are unbreakable, scratch less vision corrector that do not fog up or break on impact. They are really great choice for daily spectacle wearers and with a bit of patience can become your daily vision corrector. Here are the different types of Contact Lenses Available:


Rigid Gas Permeable (RGP) Lenses : Made of plastic, these lenses permit oxygen to reach the eyes and are great for extended use. These come in yearly versions and are relatively easy to take care of. These lenses are worn over the centre of the eyes and are less flexible than soft contact lenses. These offer excellent vision and are great for most types of vision correction. But disadvantages include greater adaptation period than soft contacts , the chances of debris getting stuck under the lens and in between the eye and the lens. Also these can slip off from the centre of the lens easier than the other types of lenses.


Daily Wear Soft Contact Lenses: These lenses are made of soft flexible materials like plastic or silicone hydrogel that allows oxygen to pass through to the eyes. These contacts are relatively expensive and have to be disposed daily so there is no need for daily care. These lenses offer great comfort but can get damaged easily. The vision correction is not as great as RGP lenses and are available in tints, bifocals and are great for active people.


Monthly Wear Contact Lenses: These are mostly made of plastic or soft silicone hydrogel that permits oxygen to reach the lens surface. With a minor adaptation period and the ability to wear them for 30 days, monthly lenses are one of the most popular lens variants. These are available in a wide range of prescription strengths and can be worn easily without a problem. Daily cleaning is necessary to keep the lens debris free and virus free.


Colored Contact Lenses: Colored contact lenses are soft contact lenses that alter the color of the iris and also may offer vision correction. These are mainly worn for aesthetic purposes and is usually available in Yearly, Monthly or daily versions.


For a first time contact lens wearer it’s essential to get their eyes checked properly and then decide upon the type of contact lenses they want to opt for. A medical practitioner can be the best person to ask all your questions regarding contact lens. There are also Single vision, bifocal, multi focal, toric and cosmetic lenses available for the wearers. If you’re a spectacle wearer and need vision correction all day, a yearly lens can be a great option. For those who want to keep their contacts debris and virus free and lessen your chances of eye problem you can choose monthly or best option would be to choose daily disposable lenses.

 Disadvantages Of Wearing Contact Lenses :

The main disadvantages of wearing contact lenses on a daily basis is the increased chances of damaging the natural eye surface. Lenses can sometimes get contaminated by viruses and debris and can cause eye problems. Also dry eyes, itching, redness and watery eyes can be associated with the over-wearing of contact lenses. To enjoy the best vision, it’s necessary to take care of your lenses on a daily basis if you’re using any lenses except daily disposable lenses. Also sleeping with contact lenses on is also discouraged (Not if it was advised by a medical practitioner).

If optimal vision correction is your requirement, then choose RGP lenses that can offer the best vision correction, since daily and monthly lenses are not as efficient in vision correction.

How To Avoid Premature Cataracts

Aging brings a few common eye problems along with it, and the most common one is Cataract. Our eyes are complex mechanisms that are also the most active muscles in our body. But with age and by heredity there occur many eye problems like cataracts, and this might be the most common one. It can be termed as a clouding over the eye’s natural lens that helps focus on images and lets us see properly.

There have been cases of patients younger than 60 years experiencing this eye problem. In fact, some patients have developed it in as young age as their 40s. Although developing it at a young age is not common, it is important to know the warning signs, potential causes, and how they are treated.

How To Avoid Premature Cataracts

Here are the main types of Cataracts:

  • A Sub capsular Cataract: This type occurs at the back of the lens and is mostly common in Diabetes patients. Also those with a history of high steroid medications have greater risk of developing this particular type of eye problem.
  • A Cortical Cataract: This type can be usually seen as a wedge like white colored opacity that develops around the lens area. These white opacities work their way to the center of the lens and this type actually occurs in the cortex area.
  • A Nuclear Cataract: This type forms in the central part of the lens and can be seen in aged people commonly.

Cataract Symptoms that You Can Realize:

It has been seen that at first these start out small and do not really affect your vision. The vision slowly gets cloudy as if you are looking through a cloudy glass. Common signs associated include feeling overexposed or seeing glares in normal light. Colors also become faded and in the case of Nuclear Cataract, you might even experience a short time improvement in your near vision.

Cause of Cataracts:

Our eyes work like the lens of a camera. It focuses the light onto the retinal surface and provides clear vision by adjusting the focus of the eye. But with age some proteins clump up and cloud a small area on the lens. This clouding can make your vision blurry. This change in the eye has doctors and researchers baffled as the exact cause cannot be traced back. But the main factors can be included as UV Radiation , Diabetes, Hypertension, Obesity, Smoking, Corticosteroid medication usage at a long stretch, Cholesterol reducing medications, eye injury, surgery, alcohol abuse, myopia or hereditary factors.

How To Avoid Developing Cataracts :

Most of these causes can be controlled with caution from an early age. One of the main reasons include UV radiation from sunlight and other sources. For that, one can use sunglasses that protect eyes from excessive lights as well as UV radiation. It’s always a good idea to wear sunglasses when outdoors whether you’re in strong sunlight or even when it’s cloudy. It’s best to wear a sunglass that blocks 100% of UV rays, is preferably Polarized for optimum vision comfort.

Also it’s necessary to follow a balanced lifestyle and avoid junk foods, alcohol or smoking to help keep your chances of developing Cataracts at young ages low. If you’re feeling a clouding over your vision get an optometrist to check your eyes and suggest solutions.

Understand What’s PD and How It’s Important

PD or Pupilary Distance is a term used in optical world and you can hear about it at your doctor or even at the optical store. But much details about this PD is not abundantly available to everyone. Many people, even those who have worn glasses for decades do not know what this term stands for. Pupilary distance is an important part of the Eye prescription, especially if you’re planning to order your new glasses online.

Understand What's PD and How It's Important

PD distance is the distance between the midpoint of the two pupils. While the lenses are prepared it’s cruicial to position optical lenses correctly in relation to the pupils of the wearer for high powered lenses because the optical center of the lenses can be aligned properly.  Knowing this value creates optical lenses with zero errors and gives best vision. So it’s important to know the PD value and your optometrist will know how to determine it.

PD distance is different for each individual but for most adults, this value ranges between 54 to 68mm. Children typically have a PD value between 41 to 55 mm. The PD distance can be measured in two ways. The first is called binocular PD Distance calculation, which is a pupil-to-pupil measurement. In this type of measurement, the values would be between 41-80 mm. The second type of measurement is called monocular PD Distance measurement, which is a per-eye measurement from the pupil to the middle of the face. In this type of measurement, the values would be between 20-40 mm.  Monocular measurements are most often used when the intended wearer’s face is not perfectly symmetrical. In this case one eye can be closer or farther from the middle of the face than the other.


PD is usually measured by your eye doctor while you’re getting your eyes examined. If your doctor does not measure your PD during your eye exam, or if it’s missing from your prescription, you can request a PD measurement. Some eyecare doctors may charge extra for a PD measurement, but most doctors will include it as part of the eye exam and write the value down in your prescription.


If you’re ordering online, you must know your prescription details and values beforehand. Even if you’re getting it done at a store, this value is important to make your lenses perfect. The details you enter are important, and it’s essential that you know the values well. In this regard it’s best to consult with your doctor and tell him to mention the values in the prescription properly.


A spectacle lens made with correct PD values will have the optical centres rightly aligned with your pupils for the best vision. So get your PD measured and mention it the next time you’re getting your spectacles done for the best fit online .
