Bifocals and Varifocals are often used when the wearer needs two pairs of glasses (i.e. one for distance and the other for reading) but prefers to have the two prescriptions combined in the one pair of glasses. People who wear spectacles full time often wear bifocals, where there is a segment in their glasses, which they look through for near tasks, e.g. reading, using a computer etc.
Varifocals are another option where the power, and hence the distance to which the glasses focus, changes progressively as the person looks through different positions on the lens. Unlike bifocals, there is no visible dividing line between prescription powers.
Costing as little as £5, it is easy to see the appeal of over-the-counter reading glasses aka ‘ready readers’ which you can purchase on the high street or internet without the need for a sight test. However, there are a number of disadvantages to bear in mind when thinking of purchasing these.
For example, they use the same strength in each lens (e.g. +2), which is very unlikely since most people require a different lens power for each eye. Also ready readers are mass-produced and many have flaws and distortions in their lenses, causing eyestrain, headaches and fatigue. In addition, they won’t fit as well as glasses that have been measured and fitted specifically for your face by a professional.
At McBride and McCreesh Opticians, we feel it is essential to have your eyes examined before buying glasses. As well as ensuring the correct prescription, we will also check for conditions such as diabetes and glaucoma, which can cause blindness.
The black spots you are referring to are most likely to be floaters in the vitreous gel that make up the main part of your eye. They are very common, and generally nothing to worry about. However, sometimes floaters can arise from the retina, which can indicate an area for concern. To make sure, we always recommend that patients with sudden onset floaters come for an eye test at the practice where the retina will be checked thoroughly.
Most people find that their glasses prescription needs updating after their operation. If you feel your prescription needs updating, contact McBride and McCreesh Opticians for an eye examination a few weeks after your surgery.
You may also find that it takes a few weeks to adapt to your vision with new glasses after cataract surgery. This is completely normal, and is due to your brain adapting to a different prescription.
