Common Signs You May Need Glasses

Trouble Adjusting To Different Lights

You may need to wear glasses if you have significant trouble adjusting to different lights. Adjusting to light can only happen if your pupils can react properly to different light sources. The faster your pupils react, the faster your eyes will adjust to the new light. Some individuals struggle to adjust to dark environments, while others might struggle to adjust to brighter light. Dry eyes might also cause an increased sensitivity to light and eye fatigue. The surface of the eye needs to be lubricated by tears, and too much dryness can lead to the death of corneal cells and exposure of the corneal nerves. Some individuals who experience light sensitivity might benefit from using polarized sunglasses that filter out glare. Other conditions that induce light sensitivity include anatomical malformations in the eye and retinal dystrophy issues. If a reason for your light sensitivity isn't diagnosed through a basic eye exam, see an ophthalmologist.
