For a vision boost, curl your hand into a fist and look through (like a telescope).
Forget your glasses or contacts at home? Try this temporary vision boost: Curl your hand into a fist and look through it, like you would a telescope.
This trick allows only a narrow beam of light to reach the retina and increases the depth of field and focus. That might be just enough to bring things into focus.
Of course, it’s only temporary (and not practical for long periods). So, maybe stash a back-up pair of glasses in your car, purse, office, gym bag or other handy place.
And don’t forget to report any sudden vision changes to your doctor. Your eyesight can tell your doctor more about your body than just how well you see. Several conditions can cause changes in vision. And early diagnosis and treatment could help save your sight.
