Clips to Spectacles, on two ball bearings

<h2>Summary</h2> <p>Choice of two sizes.</p> <p>7X20 (7X magnification, 20mm diameter lens) </p> <p>5X30<span data-mce-fragment="1"> (5X magnification, 30mm diameter lens) </span><br></p> <h2>Comments</h2> <p>Ingenious mechanism, two ball bearings, easily adjustable to any angle. In my opinion, far better than the model with the fixed clip.</p> <h2>Further information</h2> <p>Everything you need to know about <a href="/blogs/magnifiers-microscopes/magnifiers-and-magnification" target="_blank"><span style="color: #0000ff;"> magnifiers and magnification</span></a>.</p> <p>See information about (and reviews of)<a href="/blogs/magnifiers-microscopes/loupes-compared" target="_blank"><span style="color: #0000ff;"> loupes</span></a> (small high-power folding jewellers' magnifiers).</p> <p>See information about (and reviews of) <a href="/blogs/magnifiers-microscopes/binocular-magnifiers-compared" target="_blank"><span style="color: #0000ff;"> binocular (head-worn) magnifiers</span></a>- especially the <a href="/blogs/magnifiers-microscopes/binocular-magnifiers-compared" target="_blank"><span style="color: #0000ff;"> surgeons-type.</span></a><cr></cr></p> <p>See <a href="/blogs/magnifiers-microscopes/magnifiers-for-the-partially-sighted-low-vision-aids" target="_blank"><span style="color: #0000ff;"> a guide to magnifiers for the partially-sighted</span></a>.</p> <p>See <a href="/blogs/magnifiers-microscopes/uv-ultra-violet-loupes" target="_blank"><span style="color: #0000ff;"> loupes with UV lights</span></a>.</p> <p>Video (electronic) magnifiers, <a href="/blogs/magnifiers-microscopes/video-magnifiers-compared" target="_blank"><span style="color: #0000ff;"> video magnifiers compared</span></a>.</p> <p>Products: see pocket microscopes and phone microscopes, <a href="/collections/pocket-microscopes-including-phone-microscopes" target="_blank"><span style="color: #0000ff;"> click here</span></a>.</p> <p>With most magnifiers* magnification and working distance are related. <a href="/blogs/magnifiers-microscopes/magnification-calculator" target="_blank"><span style="color: #0000ff;"> Download our Excel sheet</span></a>, enter a magnification to see the resulting working distance, enter a working distance to see the resulting magnification.</p> <p>* excluding surgeons-type, digital &amp; phone magnifiers, and microscopes.</p>
