5 optician tips to make your glasses last longer!

You would never think that many of these simple habits are actually damaging your eye glasses over time. Cleaning the lenses with the wrong products can create tiny scratches on the glass and removing your glasses incorrectly can eventually bend the frame.

We have put down 5 easy tips that will help you taking care of your glasses:

 

  • Never clean your lenses with your shirt, paper or dirty pads, the tiny dust particles in these fabrics will scratch the lenses rather than clean them. Always wash the lenses with cold water and delicate soap, you can dry them after with a microfibre cloth, even better, you could get a specific lens cleaning spry from your optician. If you don’t have any of these products with you, try to blow on the lenses instead!

 

  •  Try not to take your glasses off with one hand, this will bend the frame over time, always use two, but If you are first compelled to take your glasses off with one hand, then you should do it from the center of the frame where the bridge is and not pull on one side.

 

  • Leaving them on your car dashboard is not a good idea, especially if it is really hot outside. The heat can in fact damage plastic and acetate frames.

 

  • Take your glasses off when opening the oven, draining pasta or vegetables: the hot steam can damage your frame and lenses.

 

  • Protect your glasses when using hair spry, perfumes or other chemicals that could damage them.

 

We hope you will find these tips useful! Remember you can always come and visit us at any of our HSH practices to get your glasses professionally cleaned and to adjust or replace your nose pad, all free of charge! 🙂

Contact Lenses were invented 500 years ago

The first known sketches of contact lenses were apparently produced by italian architect, mathematician and inventor Leonardo da Vinci in 1508.

Although Leonardo da Vinci never actually produced a physical model of contact lens, many believe that his ideas eventually led to contact lens development more than 130 years later .

The early contact lenses were entirely made of glass, and they covered the whole eye, including the sclera, the white part of the eye, hence they were very heavy and reduced the oxygen supply to the eye. For this reason they could only be tolerated for a few hours only so did not become very popular.

As the years went by, new materials such as plastic were developed, in 1936, New York optometrist William Feinbloom  introduced scleral lenses made of a combination of glass and plastic that were significantly lighter than older glass-blown contacts.

Later on in 1948, California optician Kevin Tuohy introduced the first contact lenses that resembled modern gas permeable (GP) contact lenses of today. These all-plastic lenses were called “corneal” contact lenses because they were smaller in diameter than previous contact lenses and covered only the clear front surface of the eye (the cornea).

Perhaps the biggest event in the history of contact lenses was the invention of the first hydrophilic (“water-loving”) hydrogel soft contact lens material by Czech chemists Otto Wichterle and Drahoslav Lim in 1959.

Wichterle and Lim’s discovery led to the 1971 launch of the first FDA-approved soft contact lenses in the United States — Bausch + Lomb’s “SofLens” brand contacts.

From that moment on contact lenses technology improved significantly until the latest introduction of silicone hydrogel contact lenses.

How to take care of your eyes on holiday!

Your summer holiday is getting closer!

Whether you’re going to spend it by the sea or exploring a new city, it’s important to consider protecting your eyes!

We have put together 5 hot tips that can help you take care of your sight while enjoying your holiday :

1) Sunglasses with UV protection: protecting our eyes from the sun is just as important as protecting our skin. The same harmful rays that can cause wrinkles, premature ageing and skin cancer also affect the eyes. UVA and UVB rays can cause damage to different parts of the eye including the retina and lens, which can lead to macular degeneration and Cataracts.

2) Sun cream: It’s not just the eye surface that needs protection, but you should also protect the skin around the eyes should it come into contact with sunlight. A sun cream of the required SPF should be used frequently to help protect from sun damage.

3) Swimming Goggles: Always wear goggles when swimming in the pool, remember that contaminants can have an effect on your eyes, and could potentially cause redness. Also, never wear contact lenses when swimming either in the pool or in the sea, as bacteria in the water can lead to a serious eye infection! You may want to consider investing in prescription goggles if you struggle with no lenses.

4) Preservative Free Dry Eyes drops:  heat, sunlight and dry air can lead to dry eyes – good idea to take eye drops with you!

5) Take a break: A summer holiday is a good excuse to take a break from the computer artificial lights! if you work long hours in front of a computer screen you are increasing your chances of becoming short sighted, according to Californian eye specialists.
