PROGRESSIVE LENSES VERSUS BIFOCALS
As we age, the need for progressive lenses increases. Just like graying hair and wrinkles, presbyopia is an inevitable sign that you’re getting older. Perhaps it started with cheaters to read but has now progressed so that prescription eyewear is necessary.
Presbyopia is the normal, gradual loss of your eyes’ ability to focus on nearby objects. Most people will start to notice presbyopia in their mid-40s. But unlike your changing hair or skin, blurred vision is much harder to live with. Thankfully, there is an answer – progressive or bifocal eyewear. We will explore the differences.
There is a distinct line in the lens with bifocals. This means bifocals only cover two different distances. With the growth of digital devices, lenses have had to evolve to cover more of a person’s field of vision.
A progressive lens is an amazing piece of engineering, allowing multiple vision fields to be incorporated into a single lens without any clear distinction between the fields themselves. Progressive lenses go from distance to intermediate to near offering a full range of clear vision. Unlike bifocals, progressives don’t have a visible line across the lens, which can be more visually attractive. You can eliminate the need for multiple pairs of glasses (i.e. reading, computer, distance) which can impact your lifestyle and tasks of daily living.
Adjusting To Progressive Lenses
Like anything new, there is an adjustment period. But consistency in wearing your progressive eyewear is key. Put away your old glasses. No-line bifocals will slightly alter your peripheral vision due to power changes that occur at the edges of the lenses. This initial difference in your peripheral vision will probably require some slight changes in horizontal head and eye movements. Make sure to wear your glasses high on the bridge of your nose and as close to your face as possible. Sensitivity to this area of the lens will diminish with time as you become more accustomed to your new lenses.
