Reading lenses come in different strengths, which refers to the power of their magnification. We offer readers starting at +1.00 as the lowest strength, increasing in increments of +0.25 up to +3.00 readers. We also offer +3.50, and +4.00 for those who need a little extra oomph in their reader strength. As any personal trainer might tell you, knowing your strength is all-important – otherwise, you might experience side effects like unfocused text, headaches, and eye strain. Check in with your eye care provider or head over to our Reader Strength Test to figure out the level of magnification you need. Your ideal readers should make you forget you’re wearing them – until the compliments start rolling in, at least.
