Your sight

 

 

 

Your eye is a wonderful organ through which we can see. The structure of eye inspired the discovery and functioning of the photo camera. The eye has natural lenses (such as cornea, aqueous humour, lens, vitreous humour);  through these structures the light coming from objects passes and end on the retina, which takes light information as a photographic film would do. Then, the retina through the optic nerve transmits visual information to the brain, which finally elaborates them in connection with other information coming from the whole organism.

Normally, light rays pass through the lenses in the visual system and are conveyed and put on focus on the retina of both eyes; then, visual information coming from both eyes are fused together giving one visual image. The visual defects derive from focusing defects, called ametropia of the visual system.

 

The most diffused visual defects are:

 

Myopia: is an optical defect for which far objects appear out of focus, whereas near objects appear clear. This happens because light rays do not have their focus exactly on the retina, but before it. Myopia can be corrected through negative lenses (indicated with the symbol -, for example -4.00 dpt) . The same symbol is used for contact lenses.

 

Hypermetropia: is an optical defect for which objects appear out of focus at any distances, mainly at near distances. Light rays do dot have their focus on the retina, but behind it. Hypermetropia is corrected through positive lenses (indicated with the symbol +, for example +4.00 dpt). The same symbol is used for contact lenses.

 

Astigmatism: is an optical defect in which vision is blurred. It is due to an irregular shape of the cornea, and therefore to the inability of the optics of the eye to focus a point object into a sharp focused image on the retina. It can be corrected through spherocylindrical lenses with indication of the axis of astigmatism. The same is for contact lenses.

 

Presbyopia: is a condition where, with age (usually around 40 years old), the eye exhibits a progressively diminished ability to focus on near objects. It is due to progressive loss of elastic properties of the lens and intrinsic muscles. It can be correctedwith positive lenses (with the symol +, for example +2.00 dpt). 

 

Glasses for spectacles

 

To correct visual defects, we use ophthalmic lenses, which are mounted on spectacles according to optometric/oculistic prescription. The material must be selected according to the need of the utilizer, and should fulfill two main requests, i.e., best physic and optic properties, and best aesthetic quality. Ophthalmic lenses are classified into two great classes: lenses made of mineral glass, and lenses made of organic material. These latter lenses have superior lightness and safety characteristics, therefore now are used with much more frequency versus the former lenses. Lenses made of organic material can be produced with various grades of index of refraction, from 1.50, of the classic organic material called “CR39”, up to 1.56, 1.60, 1.67 and up to 1.74, for newer organic materials, which can be used to build lenses as thin or even thinner than titanium lenses, but having the advantages of being infrangible and much lighter.

Spectacles with graduated lenses 

 

Please find below the procedures to order spectacles with graduated lenses:

1) insert into the cart the frame for the spectacles you wish

2) click on the key Add Graduated Lenses; 

3) select lenses suitable for correcting your sight (please see the section Prescription Lenses). Please remember that only one item (Quantity 1) should be inserted, since lenses are sold in pairs. 

4) you should insert also the exact graduation of lenses you need within the notes in the order (or through separate mail, adding a photostat copy, or exact transcription). Moreover. We need knowing your exact inter-pupillar distance, for correct mounting of lenses.

No supplementary expenses are required for mounting lenses.

Contact Lenses

 

Contact lenses are small, thin optic lenses which are directly placed on the eye, to correct visual defects.

You can wear contact lenses in order to correct diffused visual problems, as for example: myopia, hypermetropia, astigmatism, presbiopia.

 

Several types of contact lenses:

we can classify contact lenses on the basis of their manufacture material (rigid or soft material), and on the basis of how long a lens can be worn before removing it (wear schedule).

Lenses shall be prescribed also on the basis of your specific visual defects (myopia, hypermetropia, astigmatism, presbiopia).

 

Rigid lenses or soft lenses?

Most contact lenses on the market are soft, or hydrophilous; this means that they contain a great percentage of water (and therefore they maintain softness). Soft lenses are very thin and are made with materials which have oxigen permeabilità, so as to pass through and reach the eye.

Warning

Contact lenses can be applied and used only when the patient eyes can wear them with a favourable risk to benefit evaluation. The doctor can observe risk factors which may be responsible for possible complications or intolerance. The ophthalmologist and the experienced optician/optometrist are aware of such possibilities, and they have to examine with care the patient before giving their advice on the possible usage of contact lenses. Contact lens usage must follow specific insertion, removal, clearing and care schedules. Usage is allowed when no  contraindications or risk factors are given from the ophthalmologist. Control schedules must be followed with care. Sterile contact lenses can be used not beyond the recommended time. At the end of the recommended period (daily, two times a week, monthly, and so on) lenses must be replaced by a new pair. In cases of redness, burning, disconfort, irritation, lacrimation , or blurred vision lenses should be removed, and a doctor should be called. Some drugs, as for example antihistaminics, diuretics, tranquillizers, can facilitate eye dryness; in this case consult an ophthalmologist. In case of contact of a chemical substance rinse immediately with water, and consult a doctor. Avoid contact with toxic vopours and hair lacquers. Always use fresh solutions (non expired) for contact lenses whenever you put the into their case, and never rinse lenses with tap water. Do not put lenses in your mouth to wet them. Consult your doctor for correct use during sport. Avoid wearing lenses while bathing in the sea, in swimming pool and public showers. Avoid using soap with creams, lotions and cosmetic oils before wearing your lenses. Improper use of contact lenses may cause severe eye damages. In rare cases even corneal ulcers may arise, with possible damage to the vision. Hygienic rules, and wearing schedules should be always followed correctly, in order  to avoid complications such as ulcerous keratitis. Smoking is another risk factor for ulcerour keratitis. Note that contact lenses with UV protection cannot replace properly sunglasses, because cannot protect the entire anterior segment. Therefore, peoples wearing contact lenses should go on wearing sunglasses in case of exposure to UV ray

FAQ

 

1) After having received spectacles, can I give them back if I do not like them?


Following on line purchase you have 14 days to give them back to us, if you do not like them. You should write to info@suneyez.com , and we shall send you a mail with indications for the procedure. The cost of product shall be credited to your name; you shall pay only for dispatch expenses. 


2) Are spectacles original? What are the limits of the warranty?


We are authorized dealers and/or concessionaire agents for all trade-markslisted on our site, therefore all products we sell are original. The warranty is the one stated by the producers, according to the CE laws: i.e., 24 months for manufacture defects. In this case, you can write directly to us, or in alternative to the authorized dealer of your zone. 

 

3) May I buy direcly at your sales points? 


Generally, but not always all products we sell are available at our sales points. Therefore, we cannot say with mathematical certainty that spectacles you need are “phisically” available in the store, but we can warrant the immediate supplying of your needs, according to the times specified in our site, in the section “Sending and delivery times”. Moreover the prices indicated in the site Suneyez are strictly reserved to clients who purchase on line; sales points may have different sale conditions.


4) How can I purchase graded spectacles?


Procedures for purchasing spectacles with graded lenses are detailed in the section: “Guide to purchase – graded spectacles”. For any questions you may send a mail to info@suneyez.com 


5) I want to purchase a specific product (spectacles or contact lenses), but I cannot find it out in your site. What can I do?


In our site you cannot find out all products we can sell in our sales points. For example, the whole ranges of toric contact lenses (toric means that it corrects astgmatism) or multifocal lenses were not inserted, because of the complexity of these products. However, you can send us a mail at info@suneyez.com , with your specific needs, and we shall send you the best proforma invoice.  


6) I wanted to purchase spectacles with progressive (multifocal) lenses, but I  did not found this product in your price list. Why?


Progressive lenses should be adapted tightly to a specific person who has specific needs. For example we need measuring the optical center, pantoscopic tilt, (angolo di avvolgimento della montatura), and so on. All these parameters can be defined and measured only through the direct presence of the bearer, and is not possible to define them “theorically”. We strongly discourage from purchasing on line these items, in order to avoid visual damages.
