The Ageing Eye

Visual acuity begins to degrade as a result of presbyopia. Increased risk of dry eye.

Seeing detail gets more difficult as a result of presbyopia and we are at increased risk of dry eye.

Our ability to see in low light degrades and the likelihood of problems such as floaters increases.

The risks of cataracts, glaucoma and macular degeneration increase. Presbyopia advances.

Common eye conditions

Macular Degeneration
On the plus side, blue light can help boost alertness, heighten reaction times, elevate a negative mood, lower blood pressure and increase the feeling of well-being for short periods.

On the dark side, too much blue at the wrong times will make it harder to see contrast, may damage your eyes and will interfere with a good night’s sleep by messing with our circadian rhythm.

Blue light is everywhere, from your smartphone screen to the sun.

Scientists at Harvard have researched the effects of exposure to blue light. At night, it throws the body’s biological clock out of whack. Sleep suffers. Worse, subsequent research shows that this may contribute to the causes of some cancer, diabetes, heart disease, and obesity. While all light has the potential to suppress the secretion of the melatonin that helps us sleep, blue light does so very powerfully in the dark.
