Varifocal lenses explained

Varifocal prescription glasses have different prescriptions in each part of the lens, allowing people with multiple prescriptions to see clearly at all distances. Those that have presbyopia are likely to need varifocal or progressive lenses.

What is the difference between bifocal, varifocal and progressive?

Bifocal lenses have a noticeable line in the centre of the lenses that divides the two different prescriptions. Bifocal lenses can only accommodate two prescriptions, with the distance prescription located at the top of the lens and the near prescription at the bottom of the lens. Varifocal lenses have three different prescriptions in the lens. Varifocal lenses feature a distance prescription at the top, an intermediate prescription in the centre and a near distance at the bottom.

Who benefits from wearing varifocals?

Those with presbyopia experience blurry near vision; they will often also have blurry distance vision. Varifocals are a more convenient option than carrying around two different pairs of glasses. For those that are unsure if they need varifocals or not, an optician can assess the health of the eyes, diagnose any refractive errors and then suggest the appropriate ways to correct those errors.

How long does it take to get used to varifocal lenses?

There can be an adjustment period with any new pair of prescription glasses. Varifocals may take a little longer for those that have not experienced this type of lens before. Some people experience a ‘swimming’ feeling when they are getting used to varifocals, this may result from looking in the wrong portion of the glasses for the distance they are trying to view. When walking, for example, it helps to look only straight ahead and not downwards. Learning where to look through the lens for each prescription usually takes about 2 weeks, it’s important to wear the glasses consistently throughout this period. If the adjustment is taking longer, speaking to an optician may be advised.

Are varifocals more expensive?

Although varifocal glasses tend to cost more than single-vision ones, it does mean that two pairs of prescription glasses aren’t needed, which can save money. Buying varifocals online is another way to save on the cost, as prescription glasses bought online are more affordable. When buying glasses from online retailers like Feel Good Contacts the ability to shop in a convenient place and time makes shopping fast and easy.
