Contact lenses: all the benefits

Contact lenses or glasses? Although one choice is not exclusive of the other and you can alternate usage, there are still situations in which using contact lenses can help improve vision. To illustrate the benefits is Zeiss Vision Care Italy.

Better peripheral vision

Compared to glasses, this is possible with contact lenses Enjoy better peripheral vision. The lacs move with the eyes, providing optimal vision; Glasses, on the other hand, tend to block the field of vision and reflect the sun’s rays.

Perfect in any weather

Unlike glasses the lenses do not fog up and they are not subject to change when temperatures change. They are the ideal choice if you want to practice outdoor activities regardless of the weather conditions.

Freedom of movement in sports

Contact lenses are perfect for training because they stay in place and allow you to focus on the goal to be achieved. Glasses, on the other hand, can fog up and slide down your nose, making training more difficult.

UV protection

Today, thanks to technology, you can buy contact lenses UV filter to protect the eyes from ultraviolet rays which could yellow the crystal and promote the development of early cataracts.

Contact lenses on vacation: instructions for use

Particular attention must be paid to handling contact lenses during the summer season. The light-heartedness typical of this time, the This can lead to less careful and less precise eye care, associated with increased risk factors (high concentration of ultraviolet rays, dehydration, presence of irritating substances such as salt, sand and chlorine) explain why those who use these devices are more prone to injury, inflammation or infection during this period to the cornea. The experts from Bayern Clinicactually confirm that eye and vision problems increase by 25% during the summer months, mainly due to the use of contact lenses in the water.

Opt for daily newspapers

In summer it is better to use disposable lenses that do not require maintenance. this makes possible Not having to take the solutions with you on vacation, which change when temperatures are too high. But beware: many mistakenly think that the term “daily” means 24 hours, when this shouldn’t be the case when using these lenses never exceed eight hours.

Protect yourself from the sun

It is advisable to choose contact lenses equipped with a UV filter to protect the cornea, lens and retina. However, the lacs do not cover the entire anterior segment of the eye, only the central part, which corresponds to the cornea area. In order to protect your eyes optimally, you should therefore make sure that you use special artificial tears with UV protection and that you wear sunglasses even when the sky is cloudy.

Make sure your eyes are well hydrated

In very hot and windy environments such as the beach, tears, which normally ensure the balance of the hydrolipidic film, tend to evaporate more. Even the salt in seawater dries out the lens because it is hygroscopic (meaning it can absorb water). The same goes for the air conditioner in a car or plane, especially if it’s pointed at your face.

In these cases, the dehydrated lens curls up and loses strength. Even worse is that there is a suction effect on the cornea, which can cause small edema. The solution is to keep the eye hydrated at all times repeated use of artificial tears or the liposome eye vaporizerwhich is sprayed directly onto the closed eye.

Always pay attention to hygiene

Lens hygiene is essential in summer. The problem does not exist with householders. All other lens types require thorough daily cleaning and disinfection. Before cleaning the lacs, the hands must be completely clean and dry.

Fluids should be changed daily (never top up!). This is true even if the lenses have not been used, since the bactericidal effect of the solution lasts 12 hours and no more. There is a risk that the liquids will become veritable breeding grounds for germs in summer. This is due to the heat and the particular composition of the mucoproteins in our tears. Lentils should never be put in the mouth: saliva may contain bacteria.

Contact lenses in the water: hygiene rules to be observed

As Bayern-Klinik experts know, when using contact lenses in the water, it is important to practice strict hygiene and follow a few simple precautions:

  • Do not open your eyes in the water without diving goggles
  • Do not splash to avoid direct eye contact with water
  • Don’t rub your eyes with wet hands
  • Shower before and after entering the pool to prevent external agents from getting in your eyes
  • After getting out of the water, clean your eyes with a saline solution
  • Dry your eyes thoroughly, preferably with gauze rather than a towel
  • If you feel unwell, contact a specialist

Be careful with salt, sand and sunscreen

Contact lenses can also be worn while swimming in the sea. We recommend applying it an hour before so the lens is perfectly in place. At the end of the day you have to throw them away when it comes to the daily newspapers. For other lenses, clean them carefully.

If the salt causes irritation, the eyes should be wetted well with artificial tears. Or you can rinse the lenses with moisturizing liquids in the palm of your perfectly clean hand. The same goes if sunscreen or a few grains of sand get in your eyes. The main thing is not to rub your eyes. If you go diving, you can use the lenses under the mask.

Take them off if you sleep under an umbrella

According to a recent study by American researchers Centers for Disease Control and Prevention (Centers for Disease Control and Prevention), forgetting to remove contact lenses before bed is the most common bad habit among contact lens wearers. This is one of the riskiest behaviors. Eye movements during sleep can cause it micro abrasions paving the way for bacteria. Therefore, in summer, before going to sleep under the parasol, put the Lacs in the special container.

Bring spare glasses or lenses

Always carry a pair with you to avoid wearing annoying lenses. They can cause irritation or cause infections to manifest themselves. Also, in the event that a lens is lost (at sea or in the pool), it’s a good rule of thumb to always have a spare pair of lenses with you.
