Cumulative UV exposure accelerates lens clouding (cataracts). Wear sunglasses with 99% to 100% UVA and UVB protection whenever you are outside in daylight.
4. Schedule Comprehensive Eye Exams
Many progressive conditions, such as glaucoma, develop silently without early pain or obvious symptoms. A regular dilated eye exam allows an optometrist or ophthalmologist to detect changes long before permanent vision loss occurs.
When Blurred Vision Requires Immediate Medical Attention
While gradual vision changes warrant a routine visit to your eye doctor, certain acute symptoms require emergency medical care:
Sudden loss or dimming of vision in one or both eyes
Severe eye pain accompanied by redness or headache
Sudden onset of flashes of light or a flurry of new "floaters"
The sensation of a dark curtain or shadow pulling across your field of view
Copious discharge, crusting, or sudden double vision
These warning signs indicate acute issues—such as retinal detachment or acute angle-closure glaucoma—that must be evaluated immediately by a specialist.
