(Photo via Purdue)   Glaucoma is a common, yet serious, condition that occurs when the eye’s drainage channels are blocked. This causes humor fluid to collect within the eye faster than it can drain out, increasing intraocular pressure, which can damage the optic nerve and cause blindness. Luckily, it’ ...

A good flush cutter fits the hand well and has a spring action that opens as one's grip is relaxed. The cutter jaws must close evenly and not allow any sunlight to pass t ...
