Eyeglasses and Eyesight

There are more and more people suffering from eyesight issues. It is therefore common to see people wearing glasses on the street, something that was not as common a while back. This can be attributed to feeding habits as most people are focusing less and less on getting the most nutrients and more on getting the tastiest foods. Additionally, the increase in using screens (phones, laptops, television and other devices) has continued to weaken the eyes. It is therefore important to learn more about eyeglasses, especially since most people will end up wearing some to correct their vision in the course of their lives.

Eyeglass Prescriptions

You should get a prescription from an ophthalmologist or an optometrist before getting your glasses. A new trend where people visit an optician to get glasses without a prescription from an actual eye doctor is cause for concern. Some opticians convince you that you need glasses only because they need to make a sale. Opticians are technicians who are trained to design and fit glasses and should not provide you with glasses without a prescription.

Eyeglass prescriptions, like medicine, are issued to treat diseases or conditions. For eyeglasses, you could be short-sighted, long-sighted or both. Astigmatism is also another reason to get eyeglasses. In addition to these eye conditions, some people get UV light-sensitive which makes it necessary to wear glasses. All these conditions can only be diagnosed by an eye doctor. Once this is complete, the doctor then prescribes the type of lenses that you should have.

Types of Material for Eyeglasses

Glass was the most common material for lenses for a very long time. The downside to glass is that it easily breaks and could cause serious injuries if it shatters while you have your glasses on. This made it necessary to start using plastic for lenses. The good thing about plastic is that it does not shatter easily. It is therefore more durable and saves on a lot of money in the long run if well taken care of.

For people who participate in contact sports or any other sport where they have to have their glasses on, doctors prefer to prescribe polycarbonate lenses.

The size of your facial profile, shape of the face and hair all influence your decision. Most people consider eyeglasses an accessory that ought to match or work well with your outfit to achieve a fashionable look.

Do Glasses Make Sight Worse or Better?

This is one of the most popular questions among people who have glasses and those who are considering getting some according to the doctor’s orders. The truth is that eyeglasses can neither make your sight better nor make it worse.

Most people assume that their eyesight is better because they can see clearly. This is not exactly the case. The lenses only help to bring things into focus so you can see. This gives the illusion that your eyes are better. Once you remove the glasses, however, you are back in the same position.
