Astigmatism

Astigmatism is an optical aberration that affects a majority of people. While it is easy to explain and understand nearsighted and farsighted, astigmatism is a little more involved but basically it distorts images no matter what distance they are at by making them appear smudged and even double.

UV light explained

What is UV? …And why does it matter?

Light is a form of radiation. The “visible light” is a small segment of the the electromagnetic spectrum. As summer approaches we hear a lot about UV light or Ultraviolet light.

Look at sunblock and you will see blocks so much UVA and UVA, sunglasses are the same way and now some clothing and outdoor furniture also talk about UV blocking which can fade their colors over time if their is no blocking.

 

  1. UVA – Aging:
    • 95% of all UV reaching the earth
    • remains constant all year long at most latitudes
    • responsible for aging of the skin and loss of elastin.
    • penetrates uncoated glasses
  2. UVB – Sun Burns
    • more intense then UVA
    • Strongest in the summer and can be filtered out by glass
    • sunblocks work to prevent UVB penetration to the skin

Overexposure and unprotected skin can lead to skin cancer, cataract development, macular degeneration, etc. There are some positives with limited exposures like vitamin D that is produced in the skin which helps with bone strength and density as well as helpful to the immune system.

Summer is more problematic due to more UVB being able to pass through the ozone layer. Watching the weather in mid and late summer there are days where an ozone alert is posted meaning exposure to UVB is particularly high on that day, which causes more damage quicker.

 

Summer Eye Care Tips

Summer Eye Care Tips

Yes summer is upon us so how about a few summer eye care tips from your Tulsa Eye Doctor at Optique Professional Eye Care.  My father in law has had numerous lesions removed from a life of working outdoors, so why not share a few thoughts about protection.

  1. Hats are always good especially those with larger brims to prevent intense direct exposure of the face particularly the ears, nose and eyelids.
  2. The easiest is a great pair of large or wrapped sunglasses with UV protection. It is amazing the number of corneal burns that occur each year that could be avoided by using simple shades. Do not let a cloudy day deceive you there are still a lot of UV radiation getting to you through those clouds. Most people don’t even realize the damage they have done until the wake up after and hour or two in extreme pain much like wielders, who experience flash burns. Too much exposure to UV light effects the eyes in a number of ways from cataract formation, macular degeneration, pinguecula to pterygium and solar keratitis.
  3. We are more active with sports and yard work in these warmer months and safety protection should always be priority. Mowing, weed eating, tennis, baseball and basketball are just a few of the activities that you should have eye protection for.
  4. Stay hydrated and you may want to have a good artificial tear with you. The wind, heat and sun all take a toll on your tears.  The tears are the first layer that light hits when it enters the eye even though it is thin it still can help filter out some UV light.
  5. Never swim in contact lenses. If you are not concerned about acanthamoeba which may necessitate a corneal transplant.  Contacts will absorb chemicals and pollutants in the water that will be held against the cornea which may be toxic.
  6. Try to avoid outdoors direct sun from 10 AM to 3 PM when the rays are at their most intensive strength.
  7. Summer makes a great time to schedule your family for eye exams because schedules are usually easier to manage. School age children should have an annual exam prior to classes beginning in August. An annual eye exam can help with prevention and maintain healthy eyes. These exams can allow your eye doctor to detect a problem early and may be sight saving, so you can enjoy vision for summers to follow.
