Wear sunglasses with UV protection Look for sunglasses that block 99% or 100% of UVA and UVB rays. A wider brim on your sunglasses will also provide more protection for the delicate skin around your eyes.
Stay hydrated Dehydration can lead to dry, irritated eyes. Make sure to drink plenty of fluids throughout the day, even if you don't feel thirsty.
Avoid spending too much time outdoors during peak sun hours The sun's rays are strongest between 10 am and 4 pm. If you must be outside during this time, try to stay in the shade as much as possible.
Use artificial tears Artificial tears can help to lubricate your eyes and relieve dryness. Look for preservative-free artificial tears if you wear contact lenses.
Take breaks from screens Staring at screens for long periods of time can strain your eyes. Make sure to take breaks every 20 minutes or so to look away from the screen and focus on something else.
