The Beauty of Light

The Oban Times - - News - with John Wallace

One of the great plea­sures I get from my cho­sen pro­fes­sion is I travel to sev­eral west coast is­lands both pro­fes­sion­ally and also oc­ca­sion­ally on hol­i­day. For years I used to sail up and down the west coast in late May. That was when May and June were nor­mally sunny and were con­sid­ered the best time to ad­mire the scenery. My favourite time on board the yacht was the early morn­ing watch just as the sun rose es­pe­cially if we were at an­chor in some re­mote sea loch. The waves would gen­tly lap against our hull and the seabirds would start calling. As dawn broke and the sun rose the land would be bathed in a won­der­ful soft or­ange glow. A per­fect start to the day.

As we age our eye­sight changes. The lens inside each eye changes shape and colour. You prob­a­bly have no­ticed your glasses usu­ally need up­dated ev­ery two years. That’s be­cause the lens inside each eye grad­u­ally de­creases in op­ti­cal power. The most ob­vi­ous sign is when we need to push books and news­pa­pers fur­ther away to see them clearly. An­other sign is when we need more light to read. By the age of sixty we need four times the level of light we needed at age twenty one. In my house­hold the older gen­er­a­tion is putting all the lights on while the young­sters are turn­ing them off.

If you have started to de­velop cataracts your lenses ab­sorb large quan­ti­ties of red and yel­low light so sun­rises and sun­sets can be­come less spec­tac­u­lar and sun­light or car head­lights make dis­tant ob­ject hazy. If you no­tice any of th­ese changes you should ar­range an eye ex­am­i­na­tion. Cataracts are eas­ily treated and you could start to en­joy our spec­tac­u­lar scenery just as you did when you were younger.
